Congratulations to the winners! Of course we all win with a new video.
Thanks for the kind words, much appreciated. Thanks for watching.
We learned over the years to leave the old water tube grommets in the inner exhaust. Why? Because the new grommets would soon swell up and clog the water passages again. Instead, take a very sharp knife with a small blade and run it around the inside of the old grommet while it is in place. If you do it properly you will trim a round ring of rubber out of the old grommet and your water passages will never clog again. Good to go forever after that. Thanks for a great video, Michael.
I shared your comment in the up coming video. Thanks for the tip and watching
Glad to see ya Mike, I don't sweat the winning things I've always enjoyed your videos period.
Much appreciated. Thanks for continuing to watch.
Unfortunately Leeroy passed from my simple search but that site is stationary/down, i just won a 83 nine point nine at auction less than 50 had no hood but found one local a 15hp hood, a mouse had chewed the coil wires so i fix them and it started up with water, now i am looking for a small aluminum boat to put it on and a SS prop down the road it it runs well, a compression check i got 105 top 96 bottom so it's maybe so so have fun
good job. i had reed valve screws come loose so now i locktite all my reed valve screws. the more you talk the more i learn. keep up the great work.
Thank you, I may just put some loctite on them. Thanks for watching
I am very happy to win the hat. Thank you so much. Another good video and you must have spent a lot of money on parts for that Evinrude. Maybe that is the big secret. Lol.
I have put a couple of dollars in it but it should be worth it in the long run. Thanks for watching.
Yes, those are good little motors and I would rather have a vintage one for sure.
Quote of the video “tight as a frogs butthole” 😂 love the videos! just finished putting new pistons in my 85 15 horse Johnson and watching these videos inspired me to give it a shot! First ever motor rebuild for me. Next step is to start it and see if she runs. Thanks for doing what you do!
Hey thanks for the kind words and thanks for watching
Good job Mike. Always like your videos.
Glad you like them!
Liked the info on 9.9 to 15 carb difference!!!!
Glad it was helpful!
just did a water pump impellor on my 77 Johnson 35 was easy after watching you explain while doing it. And rebuilt the carb also easy peasy now need water in the lakes to test it out...Lakes here in California are extremely low...It is on a 14 foot runabouut does about 30 with me in it alone...
Nice. Glad the video helped. Sounds like that 14' boat scoots right along. Thanks for watching
Mike fyi I always change the rings as they are inexpensive and brings the engine back to full compression and adds to longevity.
Not a bad idea. thanks for watching
Congratulations you two. Love and blessings from Ontario Canada!
Thanks for watching, is it warming up in Ontario yet?
I am from Ontario too in Brockville.
@@Michaelsbackyardmarina It is certainly improving. We are currently hovering around 5C to 10C daily. That would be approximately 40F to about 50F.
It definitely is spring time. The spring Rainbow Trout creek runs are opening in 3 weeks this month. Walleye opens two weeks after that in mid May. I can actually hear the old 35HP Johnson calling me from the cottage. She wants to get out on the lake badly. A month later, Bass opens as well in June. Can't wait!
@@ralphbarker7791 Hello neighbour. I am in Oshawa, just east of Toronto. The city that used to motivate Canada till everyone raped GM till closure! Love and blessings! Tom
Mines a 1991 with electric start so its the 91 fully loaded model, its a long shift too I believe.. paid $300 for it with original 6gal tank & it came with a 3gal tank.. the original 6gal tank is like $179 itself, mine had a small air leak i fixed
Tear into that merc it’s a mystery engine for me too. I wanna see!
Me too, going to rip into it.
For impossible to obtain or need it now gaskets a cerial box a spoon an an exato knife . A small ballpeen hammer can also be useful in place of the spoon ... Tap tap tap.
Absolutely, thanks for watching
Arrrg I’ll have to find the video where you fix the skeg tip. I’m missing the piece on this 15hp evinrude I got. Just find a big chunk of aluminum? As a novice just starting to work on a couple engines, I greatly appreciate your videos. Put Giveaway in the thumbnail picture next time you do one and make people subscribe and comment. Seen other channels get lots of subscribers that way. I’m from south MS and little old 2 strokes are greatly prized around here. You’ve had a few videos that really helped me and made me a fan. please keep making these. Thanks
Just some ideas food for thought.
IMHO I would change the 2 lower crank/drive shaft seals and an o-ring while you have power head off to make sure you don't have a leak on crankshaft or drive shaft later they are in the cap with the 3 screws bolted to lower crank area it might also help to keep the worn driveshaft protected by keeping the grease you apply to top of driveshaft on it when you put it back together. Those parts are fairly cheap I just did mine.
I also just put a 15hp stinger pipe onto a 9.9hp and the water grommet was indeed melted restricting water entering the power head so it is a good idea to change them as you plan to. I also added a 15hp all metal carb to that engine which is a 1985 and it is running very well. I plan to try and take the 9.9hp metal carb I pulled off that engine and put it onto a 1989 8hp engine that came with the plastic carb and no choke but primer set-up . I will swap the high speed jet from the 8hp carb to 9.9hp it has the same/close venturi/throat size it will be a good experiment. I'm not wild about the primer set-up.
Also when you are tightening the screws or carb plastic parts they are numbered with torque sequence 1 2 3 4 5 6 etc that helps to prevent cracking. I just barely tighten them you can use a little thread lock to keep from overtightning them.
I would have been tempted to use or at least try to use the Original JB (black grey) weld on the cracked carb bowl on the outside by sanding it, cleaning it with acetone then applying the JB Weld and letting it set-up at least 24 hours. It is terrific stuff I think it would have fixed your issue with that hairline crack on fuel bowl. I have used it in the 1980's on 6 gallon Johnson metal fuel tanks before with leaks around the lower lip where they put them together. and it stopped leaking for years. If nothing else it would be a good experiment maybe giving you a back-up bowl for carb.
The top plate of your carb where yours is warped doesn't seem to be a critical area of carb IMHO when I was working on one yesterday I looked hard in that area but if it still wouldn't run right after fixing the carb bowl I would have been tempted to try using a heat gun with (top carb cover gasket removed) a small clamp to try and get it to go as flush as I can with the top plastic piece on top of carb if it wouldn't run correctly but it was running correctly I suspect the reason it stopped running correctly was the fuel was running out of the bowl or being forced out by the fuel pump at a quick rate. You might have been able to put another hole back there and drill and tap that part of carb to get that corner to go down as they added a screw hole in later years.
That second hole you showed us on the carb bowl is most likely for a fuel primer set-up and will need to have a screw and red washer put into it to prevent fuel from just running out bottom of bowl. The 1989 8hp I was working on yesterday has a fuel line to a connector there and then it goes to the primer assembly and from there to the top of reed valves through a small brass tube and when you pull primer it shoots fuel into the reed valve area this motor has no choke I bet that is what that second hole is for in bottom of fuel bowl.
The screws on the reed valves I would really use some thread lock on. I have heard people say do not use it but I have used it on my personal motors and never had a screw loosen up and destroy my engine. That's a judgement call.
I always put the bolts screws etc back into the holes they came from when I take something apart especially if it is going to be apart for a while it makes putting it back together so much easier and old mechanic taught me that its been a game changer for me. Sometimes the hardware is longer/shorter etc but looks a lot the same. It has really helped me especially not to loose hardware and quicken re-assembly by not looking for that darn screw or washer etc.
One more tip that I do is when working on those type motors or the ones with the tube spool style recoil when putting a carb on and off to see if it is right I don't put the recoil back on I use just a rope to start engine. It is also helpful when checking plugs for spark because you can stand directly behind the motor and pull the rope. It also gives you more leverage starting a motor rapping it around the flywheel which is good for older folks like me especially when a motor hasn't ran correctly or isn't running correctly.
Hope that helps
Thank you. Your tips will come in handy for sure. Thanks for watching
dang that old Wisconsin is one big chunk of old iron. the derating seems to be a common theme. i have 4 stroke 9.9 tohatsu and merc and researching them the only difference between them and their respective 15 hp is the carb
I certainly is. engines are all about making a better air compressor and then lighting it on fire.
Dang! I wanted a hat.
I will most likely have future give aways. Thanks for watching
Some epoxy on those plastic parts could have save a whole lot of dollars !!!
I've made the mistake of mixing an matching parts from poor house keeping many times !!!
Everything in a marked box could help !!!
Your clear to the reeds may as well do new ones . Use some rubber gloves to handle them !!!
I did replace them, thanks for watching
Good to see the big secret get some TLC. Get video
I would agree. Thanks for watching
Mike, I’ve just found your channel! Great job! Do you ever sell motors? I have a 14’ sea nymph (just bought) but the 30 HP Evinrude has been given me troubles and I can’t crank it now. I’ll be passing through Riverside, IA twice this summer (my sister lives there).
Think "Cow Magnets" avalible at any slaughter house or if ya have deep pockets a farm/vet supply.
For all those wayword screws washers etc ...
that works if they aren't stainless, thanks for sharing and watching.
Some lockite on those reed screws ? Because their hard on rings an pistons...
they for sure are, thanks again
I should win.
I guessed A LOT. I was right. 😂😂😂😂😂
Parts prices, getting (or are already) astronomical. The outboard motor "hobby" will soon be a Rich mans Only hobby. Same thing that happened to the old car hobby years ago. Now just Rich boy's toys.
The free market is now the Greed market.
Like someone in the outboard hobby said recently, "it's suppose to be a hobby, Not a retirement fund".
Ask for likes the give a hat away to someone that likes and comments and is a subscriber
You jabber too much, I get tired of listening to all the talk.
Then maybe my channel just isn't for your. Thanks for watching.
