Thank you. This saved my vacation this summer. Bendix wouldn't engage day 2 of vacation. New starter not available for two weeks. Watched this video, tapped bendix lightly with wrench. Unfroze and engaging. Back to fun.
My starter quit engaging with the flywheel on my 1998 Nissan Frontier P/U. Thought it was my battery so tried a jump with same results. Looked at several vids on TH-cam and found your explanation on how it all works. I plan to follow your procedure and hope to get it working again without buying a new starter. Excellent explanation, now I can troubleshoot more effectively. Thanks.
Just watched this and my eyes were opened! My boat is in the harbor, I invite people out fishing and the Bendix spins every other time. Frustrating in the dark early am. I've been pulling the cowling off, tapping the starter motor (couldn't think of what else to do) and it would engage. Once warm it would engage all day. Now it seems clear that cleaning is needed. Excellent teaching style- I subscribed.
100% correct. I have had this problem for years. Lubed the bendix. Changed the cables. No help. Changed the Bendix. Solved the problem. The backside of the teeth were worn, and as the engine "coughed" the bendix lost the bite on the flywheel teeth, and the bendix dropped out. Thanks for the good video!
i, an amateur, spent countless hours fitting n refitting the starter motor. Even the electrician couldnt figure it out. now I finally understand the problem. Thank you so much Dangar
Have a 1973 Allis-Chalmers tractor with a marginal starter. Was going to buy a replacement starter, but contacted a friend of mine who knows this stuff better than I do. He suggested WD-40 be sprayed on the shaft/gear to address what you mentioned: gummed up works. I haven't tried it yet, but your video was very thorough and helpful, showing me the details of this. Very helpful. Thanks for posting. :)
totally BRILLIANT !!! once you understand the working mechnism, logic and answers just start arriving !! people are too quick to say " bendix is shot" buy a new starter motor when in essence all it needs is a CLEAN !!! wow ! thank you so very very much , i feel chuiffed just because of the knowledge ive gained never mind anything else !!!
You are the man, i am a mechanic at a golf course and alot of our equipment have this issue. Since watching your video i have repaired the first 2 i tried...old grease and sand appear to be the issues. Thanks again
This happened to me this morning at 4am at the boat ramp. I thought i was going to have to purchase a new starter or get mine fixed. Excellent explanation. Saved me some $$$$. Thank you O
This saved me money and time. Thank you so much for the detailed explanation, I almost wasted money on a new solenoid. Followed your instructions (without removing the actual gear as it was a different circlip arrangement), thoroughly cleaned and lubed, and it worked amazingly!!! Thank you, thank you, thank you!!!
Great great video. Explanation was as clear as can be.......this is the best video of this type that I have ever seen. Keep up the great work. Wish all videos to explain and understand concepts were this clear. Great job.
Cheers from NZ mate! Easily fixed my Force/Mercury 50hp Starter Motor with the help of this video, Bendix was toast, it was engaging on the ring gear but spinning on itself! found one on the shelf for 75bux 😁🤟 2min fix!!
Can’t say how thankful I am for this video. My Ford Focus has been having a stuttering starting issue and from day one I figured it was probably something within the starter based on the symptoms. I posted all my symptoms on some Ford forums and everyone just pointed me towards my battery over and over. This excess friction on the starter motor shaft is definitely my problem.
Thank you so much for the tutorial. Pleased to report that I was able to diagnose and fix the starter motor on my law mower as a result - thanks again!
This video is worth watching. Solved my problem with this same issue. I searched for a few days and finally came across this video. Best move I did. Thank for sharing your video
Just did this for my lawn tractor that I use to push snow. Every cold snap it wouldn't work if it was warm out it would start up no problems. Took it all apart and cleaned it with some electrical contact cleaner, then used some dry graphite lube for the bendix spline and shaft. That things starts like it never had a problem. Thank you for this awesome simple video.
I installed a new starter motor 2 years ago as the old one was shot, new one worked like a charm but recently has had this issue of not staying engaged/not even trying to engage, behaviour is constant but random if that makes sense. I’ve been looking online for anyone to help me understand how and why this could be and you my man are brilliant. I have no doubt this is the cause on my boat and will give this fix a go and let you know. Thanks for sharing. It really is appreciated.
Great video, it helped me very, very much!! Thank you for the excellent detailed information and how to explanations....I would love to see more of these.
This video has been a great tool for me. It has helped me diagnose a problem as very new and inexperienced boat owner. This is also so helpful understanding the physics of it as someone who is just starting to study engineering. Thank you for being awesome!
Thank you very much for taking the time to explain how the Bendix / Pinion gear actually works and in a way that most anyone can understand. As soon as you explained how the gear actually rises on the shaft, I knew what the problem was. This starter in a Nissan D21 has been sitting for 13 years. Thanks again.
Thanks mate, glad you like the video. Too often these days I see people replacing parts without really understanding what is going on. All the best with your new career. Being a mechanic can be very rewarding and enjoyable. :)
Great instructional video. The Bendix can also not engage if your battery power system is faulty, in that its not spinning up the starter quick enough to over-come that inertia you speak about.
Great video. My snowmobile starter is spinning but not starting the engine. Someone online told me it was the bendix but I had no idea what that meant. Now I have a much better idea of what is going wrong. Thank you !
Finally this video helped me. After asking many mechanics… replacing my solenoid, replacing my starter (which was not functioning), now the new bending gear is sticking on the new starter. Frustrating. I replaced the bending gear with the old one and it doesn’t stick according to my hand test but after I shot white lithium grease in those strap threads on the shaft, I seem to have cursed it.
Many Thanks! I realize that this is an older thread, but much appreciate the detailed tutorial, (especially the insights/comments regarding inertia of the pinion). I'm currently up in the Wrangell St. Elias mountains of Alaska, fighting mosquitoes while fixing the starter on my Arctic Cat snow machine for next winter; (the pull-starter is back-breaking work), and really appreciate this thoughtful tutorial with an engineering context. Much appreciation for the thorough tutorial.
ThankYou! Went through the joy of a ring gear install in my 77 401ci Jeep that resulted in starting to chew it up again , As the Jeep was my fathers whom has passed , my urge to convert it to an anchor was not a option . New ring gear , starter , trans and case bushings , fasteners , all installed correctly with good engine mounts . And the trouble surfaced again . To date I must say I have taken a bit of a beating from this starter issue . I recall my Dad saying "Don't care if it looks like the same part or what color the wires hoses or plugs are , "Ya just gotta know how it works is all , That's the first step to fixing something . Got no business out here in the shop if ya haven't learned it yet" . You have reminded me how right he was . You obviously have done your homework and mine . I browsed TH-cam at random today and I not only found your post , it made total sense . For what its worth if I win the lotto your on my good list ! Cant thank you enough for your posting . Armed with your explanation I now have the problem where it needs to be , Somewhere else ! And I am a believer you cant afford not to spend the extra monies for top shelf parts . You and Bosch are my new friends . Good Luck and I ThankYou! again
+RM RM Thanks mate, I'm so glad the video helped you. I was really pulling my hair out with a starter motor problem until I finally took the time to figure out how that pinion gear actually worked. Once I understood that the problem was obvious. I love hearing about people working on projects that are dear to them rather than just a job. I wish you all the best with getting it up and running. :)
Can’t thank your enough. Got my boat back on the water. Luckily it locked up at end of the day at the dock so easily fixed at home with your video. Bigly thanks 👍🏼
Sweet ... you answered my question and I am now able to plow my drive - which has 14" of snow. Thank you for your well presented, clear explanation. Friction was weighing me down and a bit of dry lube was the solution.
Awesome big thanks for sharing!!! My car did this type of spinning without starting. It's starting now like it should thanks to you! Saved a couple of € because of you, so thank you so much! Awesome content!
Thanks for the indepth video mate. I was searching for ages on a youtube video on this. This is what got my mower running again. Kudos to you mate. Keep up the good work.👌👌
Great video. I just took my starter off and cleaned it up like you suggested. Purchased some dry lubricant and put it back together. Its seems to work fine now. I started it 4 times and it started just fine each time. Will try it a few more times over the next few days but it seems like this fixed it. Thanks
After watching the video carefully, I understood that what I had initially asked was explained in detail in the video. Thanks a lot for the clarifications. So I deleted the original question, it was useless.
Thanks for the demonstration. Great detail in understanding the mechanics of the parts. Your solution saved money and time out of the water. Engine started right up!
Mercury 500 50hp circa 1972 outboard had this same problem. After cleaning and lubricating did not fix it, I pulled it apart to find that it does not have a ratchet mechanism inside. It uses a solid rubber tyre that when compressed and I assume some centrifugal force is applied, it grips the inside of the casing. Lubrication is what caused the problem. I cleaned all traces of lubricant and used Electrical Contact Cleaner to ensure everything was dry with no residue. Put it back together and it cranked the motor like brand new. I don't know if my Bendix is genuine Merc or after market. Hopefully this helps some folks out there. Thanks Dangar Stu fort all your amazing videos.
This is super helpful. My Triumph Thruxton has been sitting for a few months while I wait for parts. Today when I tried to fire it up I only heard a spinning sound. So I know the starter motor is working. Now I have a goal as to what to look for as a possible fix. Thanks again.
What an awesome video. You’ve just saved me over £100 on what I thought was a ruined SM. Managed to clean the gear in situ so it was a double win. 👍🏻 Thanks...
Thanks for the video....I was told I needed to replace the starter...but when I saw this video, I did the cleaning and reinstalling...The starter works like NEW...Thanks ...
you are a gem,,saved me £220 garage quote for new one fitted,, I'm a complete novice, had to borrow tools from my good old dad to attempt the job,,,just took my time removing the thing then followed your instructions and hay presto my van now starts first turn of the key,,,thank you so much,,
Thank you so much! You are incredibly knowledgeable and helpful. Was worried I would have to replace the starter. Took it apart and cleaned the spindle and now it engages perfect and the engine starts so much easier! Thank you for taking the time to help us out!
Been doing mechanic work on hundreds of cars and this gives me a lot of insight on how it works and how I can stop throwing money away on new starters/bendix/solenoids, etc. My bendix is grinding occasionally on my Fatboy and been driving me nuts so I'm trying this before buying the whole shebang this time. Besides its winter in Minnesota and its inside for the winter so why not. Thanks for the great video.
Thanks Tim, glad you got something out of the video. Some people find this type of theory a bit boring but I figure once you understand how something works then you can diagnose problems so much better.
No problem and thank you for the info. To each their own when it comes to theories because some understand it one way and some in other ways... I didn't think it was all that boring, Thanks again.
Thank you so much about this s information, you saved me a lot of money, exactly the problem I was experiencing, Bendix not engaging with a flywheel, I applied lubrication slightly on the pinion gear, eventually it engaged and turned the engine🫡👏👏👏👏.
Brilliant explanation and thanks for going a good speed with tech talk. Most frustrating thing on you tube is people going so slow that it takes 10 mins to explain something simple or vise versa. You get it just right for me.
Thank you very much for the video. I just bathed the bendix/pinion in penatrol and worked it for 15 minutes or so and now it is engaging every time. Must of just been kind of gunky inside.
excellent explanation thank you, I will be doing this tomorrow on my Johnson outboard that won't stay engaged in the flywheel, it drops out prematurely making it hard to get it started.
Ended up being a 7 year old dying cranking battery. So never got to the starter. But I feel confident about tackling the starter after watching the video. Thanks.
Thanks for the info. I had exactly the same issue but found out the problem wasn't with my starter. I had accidentally switched the baterry terminals around (in a moment of mind blackout), and this caused the starter to rotate in the other direction, which didn't make the gear to rise up.
Thank you so much I had no idea what was wrong with my mower I took the engine and electronics half apart. After watching your video I sprayed the gear with wd40 and played around with the top nut and my mower started right up
Cheers man. Nicer to see something that fits the issue exactly, and a full explanation as well vs the BMW forums "Just get a new battery. Replace the Solenoid" kind of stuff. Old-ish starter so either old grease or the wee clutch is worn. Nice and easy
Thanks very much for this video. I just got my first boat, and it had been running fine. I caught my son playing in the boat switching the gears without it running. I'm not sure if that is what caused my starter to not work the next time I went out, but it would spin but not engage the flywheel. I put a ratchet on it and it has fixed the problem.
Great video - a mouse moved into my lawnmower over the winter and gunked up the starter. The gear wasn’t rising as you suggested. I took it apart, soaked it in gas, cleaned it up, reassembled and lubricated. Boom tractor started right up. Great technical explanation - loved it. Take a like and sub.
iI didnt think id find a video telling me exactly what i needed to know with why my starter motor problem 10:50 it was more and more regularly not coming up long enough, or now at all to connect with the engine. i thought the thread or? (teeth) at the bottom were extreemly worn out and i needed to replace the part or starter motor all together. But luckily now you've show me its just most likely just the 3rd long overdue job of 'clean n lube' with my old Mercury engne. Thanks!!!!
I revived a stuck mercury starter it spins quickly but the bendix doesn't engage, sounds just like this has lots of old grease on it. I really appreciate your videos, especially the electrical ones very well explained.
Greatly appreciated this video as we sort out our repeated starter problems. Looks like the top nut of our mechanism is flying off, and the pinion piece gets stuck in the flywheel. We'll see if we can tighten it down more than last time. Thanks again.
Thank you for the lesson on how these starter motors and bendix's work. I am having an issue with my Ski-Doo and you've explained it perfectly I believe. Now I'm off to figure out how to remove the starter assembly so that I can put this to good use.
Wow! Thought I had a bad starter while trying to do a compression test and I had all the spark plugs out. Realized the motor spun up fast enough to release the gear. Put spark plugs back in to give some resistance to the starter and boom! Fixed. Thanks for all the videos. Its helped me tremendously along my path of putting together a 96 200 HP Evinrude.
Thanks for this. I had a slow oil leak for a while now from rocker cover gasket drooling over starter motor. Oily gunked up mess had built up around the spline, so I hit with degreaser breaking down build up and the gear ⚙️ no longer a spins with spline. Pajero 2001 3.5l petrol ⛽️
Big thanks mate. I was going to buy new starter motor today for my pathfinder for $420 today. But definitly will give a try tomorrow and see if i have any luck.🙂
Helpful vid. I have noticed on a bench test (out of the engine 9.9 Tohatsu) that the pinion drifts back down with two different brand new starters. Not a problem if there is any load at all i.e.. the flywheel. Touch with a glove or rag, the smooth outer surface of the shiny silver part to demonstrate a little load. The pinion stays up as it should.
just got back from boat launch. worked 2 days ago. got to boat launch and starter gear wouldn't go up. hooked up boat and drove home. gonna try this. thanks
Thank you. This saved my vacation this summer. Bendix wouldn't engage day 2 of vacation. New starter not available for two weeks. Watched this video, tapped bendix lightly with wrench. Unfroze and engaging. Back to fun.
My starter quit engaging with the flywheel on my 1998 Nissan Frontier P/U. Thought it was my battery so tried a jump with same results. Looked at several vids on TH-cam and found your explanation on how it all works. I plan to follow your procedure and hope to get it working again without buying a new starter.
Excellent explanation, now I can troubleshoot more effectively. Thanks.
Just watched this and my eyes were opened! My boat is in the harbor, I invite people out fishing and the Bendix spins every other time. Frustrating in the dark early am. I've been pulling the cowling off, tapping the starter motor (couldn't think of what else to do) and it would engage. Once warm it would engage all day. Now it seems clear that cleaning is needed. Excellent teaching style- I subscribed.
All instructional videos should be so clear! Absolutely spot-on.
Thanks mate! :)
mate everytime i have an issue with a boat over the last god knows how many years i can always find a video with a solution from you, legend!
100% correct. I have had this problem for years. Lubed the bendix. Changed the cables. No help.
Changed the Bendix.
Solved the problem.
The backside of the teeth were worn,
and as the engine "coughed" the bendix lost the bite on the flywheel teeth, and the bendix dropped out.
Thanks for the good video!
i, an amateur, spent countless hours fitting n refitting the starter motor. Even the electrician couldnt figure it out. now I finally understand the problem. Thank you so much Dangar
You're welcome, I hope it works for you.
Have a 1973 Allis-Chalmers tractor with a marginal starter. Was going to buy a replacement starter, but contacted a friend of mine who knows this stuff better than I do. He suggested WD-40 be sprayed on the shaft/gear to address what you mentioned: gummed up works.
I haven't tried it yet, but your video was very thorough and helpful, showing me the details of this.
Very helpful. Thanks for posting. :)
You're welcome mate, hope you get your starter working. :)
totally BRILLIANT !!! once you understand the working mechnism, logic and answers just start arriving !! people are too quick to say " bendix is shot" buy a new starter motor when in essence all it needs is a CLEAN !!! wow ! thank you so very very much , i feel chuiffed just because of the knowledge ive gained never mind anything else !!!
Thanks for this. Now I understand. I had what I thought was a bad starter. I cleaned and lubed the bendix and all is now well.
Excellent!
Can I use w40 to clean and lunricate it ? What did you use to clean it
You are the man, i am a mechanic at a golf course and alot of our equipment have this issue. Since watching your video i have repaired the first 2 i tried...old grease and sand appear to be the issues. Thanks again
This happened to me this morning at 4am at the boat ramp.
I thought i was going to have to purchase a new starter or get mine fixed.
Excellent explanation.
Saved me some $$$$.
Thank you
O
This saved me money and time. Thank you so much for the detailed explanation, I almost wasted money on a new solenoid. Followed your instructions (without removing the actual gear as it was a different circlip arrangement), thoroughly cleaned and lubed, and it worked amazingly!!! Thank you, thank you, thank you!!!
You're welcome mate, glad it's working now. :)
Great great video. Explanation was as clear as can be.......this is the best video of this type that I have ever seen. Keep up the great work. Wish all videos to explain and understand concepts were this clear. Great job.
Cheers from NZ mate! Easily fixed my Force/Mercury 50hp Starter Motor with the help of this video, Bendix was toast, it was engaging on the ring gear but spinning on itself! found one on the shelf for 75bux 😁🤟 2min fix!!
Can’t say how thankful I am for this video. My Ford Focus has been having a stuttering starting issue and from day one I figured it was probably something within the starter based on the symptoms.

Kinda fun to watch this old vid and thus see how much better you have become at presenting.
Skill level high as always!
In the first 3 minutes of your video explains exactly what my starter issue is. Thank you. Unfortunately somebody stole my ring spreader.
Thank you so much for the tutorial. Pleased to report that I was able to diagnose and fix the starter motor on my law mower as a result - thanks again!
This video is worth watching. Solved my problem with this same issue. I searched for a few days and finally came across this video. Best move I did. Thank for sharing your video
Tanks for a super good video from a young Norwegian. Helpt me a lot
Thanks for the information that l was looking for. Problems with a starter motor turning not engaging engaging
Just did this for my lawn tractor that I use to push snow. Every cold snap it wouldn't work if it was warm out it would start up no problems. Took it all apart and cleaned it with some electrical contact cleaner, then used some dry graphite lube for the bendix spline and shaft. That things starts like it never had a problem. Thank you for this awesome simple video.
Thank you for that thorough explanation. I think it'll help me to fix my starter

Aww mate I think you've just solved my problem with a 60 HP Yamaha 2 Stroke.
Its exactly what its doing.. Thank you heaps man... From New Zealand
Glad to hear the video helped, good luck!
Great video, it helped me very, very much!! Thank you for the excellent detailed information and how to explanations....I would love to see more of these.
Brilliant.
Cleaned Hitachi / Tohatsu outboard Bendix starter as you demonstrated.
Thanks.
This video has been a great tool for me. It has helped me diagnose a problem as very new and inexperienced boat owner. This is also so helpful understanding the physics of it as someone who is just starting to study engineering. Thank you for being awesome!

Oh, boy! I am so grateful for this video! Hopefully, you have shown me how to fix my Bendix problem on my Electric Start lawn mower. Thank you.
Thank you! So hard to find info on a starter disengaging while cranking.
Great video, I've changed 10+ starters over the year and have never understood quite how the bendix worked. Thx
Man great video. It's nice to see some actually knowledge being spread to our youth. I'm a young mechanic and knowledge like this is hard to come by.
Thanks mate, glad you like the video. Too often these days I see people replacing parts without really understanding what is going on. All the best with your new career. Being a mechanic can be very rewarding and enjoyable. :)
This was a big help. After watching I was able to quickly get my starter motor on my lawn tractor to work properly again! Thanks!
You're welcome, glad it helped you. :)

Thank you for taking your time and explaining this. I’m having an issue with my Jeep. So this really opened my eyes to how to fix it. Cheers.
Thanks for the video. We were able to "fix" the starter motor pinion just by trying to take it apart (it got unstuck and started working well).
9:48 EXACTLY what my Mercury sounds like. I'll have at it tomorrow. Thanks!
What an awesome video. You’ve just saved me over £100 on what I thought was a ruined SM. Managed to clean the gear in situ so it was a double win. 👍🏻 Thanks...
Great to hear!

No problem and thank you for the info. To each their own when it comes to theories because some understand it one way and some in other ways... I didn't think it was all that boring, Thanks again.
You are a bloody genius mate. Fixing my starter motor and your vid sorted it! Thank you!!!
Glad it helped
Thank you so much about this s information, you saved me a lot of money, exactly the problem I was experiencing, Bendix not engaging with a flywheel, I applied lubrication slightly on the pinion gear, eventually it engaged and turned the engine🫡👏👏👏👏.
Brilliant explanation and thanks for going a good speed with tech talk. Most frustrating thing on you tube is people going so slow that it takes 10 mins to explain something simple or vise versa. You get it just right for me.
Thank you very much for the video. I just bathed the bendix/pinion in penatrol and worked it for 15 minutes or so and now it is engaging every time. Must of just been kind of gunky inside.
Great to hear you got it working again.
Thank you for sharing this, I fixed my not rising starter gear using your advice, greetings from Chile
excellent explanation thank you, I will be doing this tomorrow on my Johnson outboard that won't stay engaged in the flywheel, it drops out prematurely making it hard to get it started.
Did this work for you? I have same problem on my 90 Johnson.
Ended up being a 7 year old dying cranking battery. So never got to the starter. But I feel confident about tackling the starter after watching the video. Thanks.
Glad you got to the bottom of it, old batteries are often the culprit.
Thanks for the info. I had exactly the same issue but found out the problem wasn't with my starter. I had accidentally switched the baterry terminals around (in a moment of mind blackout), and this caused the starter to rotate in the other direction, which didn't make the gear to rise up.
Thank you so much I had no idea what was wrong with my mower I took the engine and electronics half apart. After watching your video I sprayed the gear with wd40 and played around with the top nut and my mower started right up
Cheers man. Nicer to see something that fits the issue exactly, and a full explanation as well vs the BMW forums "Just get a new battery. Replace the Solenoid" kind of stuff. Old-ish starter so either old grease or the wee clutch is worn. Nice and easy
Please never stop making these videos. They are the best!!
Thanks very much for this video. I just got my first boat, and it had been running fine. I caught my son playing in the boat switching the gears without it running. I'm not sure if that is what caused my starter to not work the next time I went out, but it would spin but not engage the flywheel. I put a ratchet on it and it has fixed the problem.
Hey mate, you're welcome, glad you got it fixed. :)
Great video - a mouse moved into my lawnmower over the winter and gunked up the starter. The gear wasn’t rising as you suggested. I took it apart, soaked it in gas, cleaned it up, reassembled and lubricated. Boom tractor started right up. Great technical explanation - loved it.
Take a like and sub.
iI didnt think id find a video telling me exactly what i needed to know with why my starter motor problem 10:50 it was more and more regularly not coming up long enough, or now at all to connect with the engine. i thought the thread or? (teeth) at the bottom were extreemly worn out and i needed to replace the part or starter motor all together.
But luckily now you've show me its just most likely just the 3rd long overdue job of 'clean n lube' with my old Mercury engne. Thanks!!!!
Glad the video helped. :)
I revived a stuck mercury starter it spins quickly but the bendix doesn't engage, sounds just like this has lots of old grease on it. I really appreciate your videos, especially the electrical ones very well explained.
+alnbaba Yep, if it just spins and doesn't rise it is bound to be old grease. Clean it up and it should work just fine. :)
Bravo colleagues.

Hello!
Greatly appreciated this video as we sort out our repeated starter problems. Looks like the top nut of our mechanism is flying off, and the pinion piece gets stuck in the flywheel. We'll see if we can tighten it down more than last time. Thanks again.
Maybe try a bit of loctite on it too.
Perfect! Saved me $$ and having to mow my lawn with a weed trimmer...again! Hello from Buffalo, NY USA
Great video -- through explanation of how the solenoid works and how to fix possible problems!!
Great explanation and visual demonstration of a starter. Thank you so much, this really helps. 👍🏻
Thank you for the lesson on how these starter motors and bendix's work. I am having an issue with my Ski-Doo and you've explained it perfectly I believe. Now I'm off to figure out how to remove the starter assembly so that I can put this to good use.
You're welcome mate, good luck with the repair.
I replaced my starter selenoid, thinking that it was the problem. But not, i think this is the main problem. Excellent video explained 👍
This is an extremely good demonstration. Very good video.
Thanks mate. :)
Wow! Thought I had a bad starter while trying to do a compression test and I had all the spark plugs out. Realized the motor spun up fast enough to release the gear. Put spark plugs back in to give some resistance to the starter and boom! Fixed.
Thanks for all the videos. Its helped me tremendously along my path of putting together a 96 200 HP Evinrude.
Spot on video, easy fix and worked perfectly. Thanks for the clear explanation too
Great video explaining from a professional, very impressive, thank you for the best information.
Glad it was helpful!
Thanks for this.
I had a slow oil leak for a while now from rocker cover gasket drooling over starter motor.
Oily gunked up mess had built up around the spline, so I hit with degreaser breaking down build up and the gear ⚙️ no longer a spins with spline.

Helped really good I was trying to figure out my new 79 dodge motorhome and I'm trying to learn the older style of non electronic motors
Big thanks mate. I was going to buy new starter motor today for my pathfinder for $420 today. But definitly will give a try tomorrow and see if i have any luck.🙂
Thanks for all you share! You have the best information and knowledge of boats and boat motors!! thanks again for this particular issue.
Good video thank you. Very clear and helped me to understand what I am looking for when my starter engages briefly and then disengages.
You're welcome, glad it helped.
Great educational and instrumental video! Now I understand how these work in order to repair it.
Helpful vid. I have noticed on a bench test (out of the engine 9.9 Tohatsu) that the pinion drifts back down with two different brand new starters. Not a problem if there is any load at all i.e.. the flywheel. Touch with a glove or rag, the smooth outer surface of the shiny silver part to demonstrate a little load. The pinion stays up as it should.
just got back from boat launch. worked 2 days ago. got to boat launch and starter gear wouldn't go up. hooked up boat and drove home. gonna try this. thanks
