- We take on a different project in this weeks episode- Troubleshooting a 2000 Ski Nautique with a Ford 351 Engine- Branded as a PCM GT40. This boat belongs to a good friend of my dad and we take on the challenge of trying to find the problem of a random miss/no start/ no hot start situation. Thanks for watching!

You’re a very smart young man, now I know why Matt has you do repairs for him. Great job Sir👍👍😎😎🍮🍮
Excellent job Sam you diagnosed that Fjord’s problem with hardly and effort on your part. Sir you made it look easy and Matt at diesel creek is extremely lucky to have you as a friend and I see why he’s always calling you when he gets stumped on his projects. With your great attitude and your always smiling your channel should grow extremely fast. I really enjoy your content and anticipate your next video. Thanks you.
Enjoyed watching your diagnostic and repair. Glad to see you didn’t jump to parts throwing!
I love this channel! You should have a half million subscribers! I wonder how many of your viewers get the "Strange Brew" reference "Beauty Clark!"
I think you're the first one!! My parents loved that movie I grew up watching it many times lol It is a great one. And thank you for the kind words!
Definitely, a “woo hoo”. Great troubleshooting.
Is there no end to this blokes talents - good job Mr Scrappy
"Maybe we can see where the smoke came out" absolutely dry line delivery there.. laughed til i cried 🤣
Good video. Interesting problem.
I have found the 2 main issues when working on boats.
Fuel being number 1. People let it sit over the winter and it phase separates.
Corrosion being number 2. As you found in the distributor.
But, also the main wire harness connector will give you the same symptoms.
Or even a corroded ground.
Pretty clean boat for it's age.
Thank you Sam.
Cheers.
Spot on!
It sounds much better let us know when is in the water love to see it 👍 👍
I will report back in May!
Great work Sam! I learned a lot watching this video. I have had a hot restart issue with this boat for 5 years. I was starting to lose friends from the carbon monoxide! Most folks just buy a rebuilt PCA for $1100 without figuring out the source of the problem. The biggest issue with my boat was when you shut the engine off for 5 minutes between skiers, it would not restart until the engine was completely cool. It seems that was because the Hall effect sensor loosened up when it got hot? I guess I could have told you I left the coil disconnected from when I did my compression checks!
I really did not want to give up on her because the 2000 ski nautique 196 with TSC1 hull has a great wake and the PCM Ford 351 GT-40 has plenty of power. Thanks so much for the rescue! Matt
bud... where's there the tracks???
Oh they’re coming
In the end the engine sounded much, much better on the video than it did when you started.
Great job Sam that’s a nice boat for its age think you’ve nailed the problem as it sounds much better and even when running now take care and all the best 👍❤️🔧🔧🔧
Not many know how to use a scope anymore. Great troubleshooting.
The Hall effect sensor would also hate any rust or filings from the contact and would give a bad signal back to the ECM. With ignition, clean is king..
Very nice job, Sam
And always a smile on your face 👍
Made for great viewing bro and looks like a good result. Safe travels. Ken.
Awesome and outstanding as always.Thanks for sharing and taking us along
Glad you enjoyed it
I wish a Happy New Year to you and your family . Greetings from Germany.
I see why Matt counts on you for help your very very smart man and a good friend to have around and you know what you're doing on a job if you don't you will find a way to make it work you figure it out that is a sign of a man that don't give up very very very smart special person
Great job Sam they owe you a water skiing adventure 😅😅😅😅
Great vid Sam. Finding faults like that can be very difficult but I’m pretty sure you’ve nailed it. Been in similar situations with cars. Trigger sensors can be a PITA.
Nothing more fun than troubleshooting old Ford TFI and EFI systems. Slop in the distrib can cause a lot of headaches along with the pip sensor. Best thing I did was go to a Megasquirt stand alone PCM on my Mustang with a crank trigger
I’ve got a 1993 ford lightning with the 351. Chased an intermittent heat related ignition issue for a couple weeks. It was the pip sensor. It’s common enough I keep a spare one around now. Not a bad repair with a small shop press to assist and once you know what to look for. I only use the motorcraft stuff for anything electronic now. The parts store stuff is garbage. Great video!
Warning on the boat stuff… if you run it dry even for a few seconds it can burn up the rubber water impeller extremely quick. The owner may want to freshen that up now in the spring. It really should be done every couple years anyway. When they fail, it will overheat in a hurry.
Good reminder; I’ll replace the impeller.
The “oil slinger” is a collar that sets the end play of the gear for proper mesh with the cam shaft. Another great video.
Good Morning Sam...Have a great Saturday..
Good morning!
Sam I want to see more of you and your dad, makes me want to connect more with my dad and do stuff!
Interesting trouble shooting, I like that you didn’t fire the parts cannon at it, always fun watching you go thru the paces to bring the solution to bear on the problem. Thanks for the video young man.
Good call, intermitterend spark, not starting, a day later starting, etc -> Hall sensor. On BMW motorbikes ;)
Sam you have a very
Realalistic approach to problem solving I really admire you and Matt have a lot incommon
You lead in electronics I am a big fan of you both keep it up and best wishes with future endeavors
Cornelius Vanderbilt once said "A boat is a hole in the water that you try to fill in with money". This was after buying a shipping business and finding out what ship repairs cost. Cool video, thanks much!
I have much respect for your trouble shooting skills Sam, and I really enjoyed the video you and Matt did on the old ford service truck over on diesel creeks channel. Thanks and I’ll see ya on the next one. (Which might be boat , or maybe a dozer, or a golf cart ,or a cable operated shovel) I love it all.
Sam, a great way to help check things out on what is a car engine in a boat. 😊
I thought distributor when I Saw it being a Hall effect one. Had an 86 bronco that I had to do what you did to. Pain in the shnoz but worked for me. Thanks for the memories.
Love your videos brother - keep doing what you do it’s appreciated. Also enjoy when you and Matt have projects. Happy New Year
Brilliant and your patience is amazing..great job ,thanks for sharing and stay safe
Brilliant video Sam watching from Edinburgh Scotland UK 🇬🇧 👏
I had that star wheel bend to the point of tearing the whole guts apart in a '95 351.
Nice work Sam. You have to remove the distributor and the drive gear to change the hall effect sensor? That must be another of Ford's better ideas because I don't have to do that on my Dodge.
As far as i know that is the only way. I was surprised myself
Bust Out Another Thousand.🍻
Hi Sam.
I am a new addition to your channel.
I been with Mat for some time now and starting to see that you guys are good friends.
Both of you put up good content and your problem solving is brilliant.
Electrical issues wouldn't be my strong point but I enjoyed you problem solving on this project it great.
Thanks for the videos and looking forward to you next ones.
You have a great sense of humour which works well during you videos.
Thats awesome. Nice work my friend chasing down the problem. Hope it works well and maybe a video on the test run when it warms up.
Thanks for the hang out time
I used to have one of those motors, the long fuel canister in the front corner has a high pressure fuel pump in it that blows a hose and causes low fuel pressure. You have to unscrew the housing to get the high pressure pump, filter and hose. The stock fuel pump is a transfer pump. It wil run at low speed but not under load due to the low pressure. It goes into a limp mode.
I have a somewhat similar problem on the S&S V Twin on my Morgan Three Wheeler. Particularly noticeably as being a hard starter. I have come to the conclusion that it is a weak crankshaft position sensor which controls the spark. These were currently out of stock at most Morgan dealers and S&S as well. Fortunately a UK based engineer has come up with a fitting kit to use a Kia sensor and it is half the price for the whole kit compared with the original S&S sensor.
Once you rule out the obvious leads/cap/plugs/rotor the top 2 causes for misfires on any electronic ignition Ford engine from the 70's onward are the ignition module and the Hall effect sensor, coils usually last forever (especially the newer transformer style ones) but the more fragile electronic parts don't fair well with heat cycles and vibration.
Good Job it’s sounding better now!
PCM or INDMAR use the ford small blocks for ski boat applications. They use the ford small block because they have a narrower block and hence a slight bit more room in the boat than a 5.7 Chev.
Can't believe you missed that coil wire . LOL
😂😂 I know I know we found it!
LOL
Pappy Scrappy……….good stuff!
That propulsion package was based on the Ford truck engine
MM77 Approved 👍🏼👍🏼
Sounds like water in the fuel - speaking as someone else who owns a hole in the water you throw money into.
Sam have you talked to Clinton at C&C Equipment, he has done a lot with the different computers that run the dozers and such, just don't tell him he is really quite good at it, hope this helps in the future.
Another good one 👍👍👍👍👍
Yes its a fuel rail pressure issue!
Hi guys from Victoria Australia 🇦🇺
Great presentation.
What ya know about Kubota 4 cyl diesels. I've got a B3200 4 cyl diesel that smokes up a storm at cold starts. After that zero smoke. I've been told it needs valve guide seals another line said it is just unburned fuel on starting.
ahh that engine brings back memories it looks just like the 5.0L 305 that my 91 LTD vic had man sometimes i miss that car but it was a nightmare in the snow like we have now
302 not 305
@@Dave-in-MD ahh yea thats right been a long time since i had that car like 14 or 15 years now
I was sure glad when you found the MIA coil wire. I was starting to get concerned about your ignition knowledge.
You and me both! lol it was hard to watch the playback of that
Nice work!
the problem seems to be on the timing sensors which are most probably on the fly-wheel that has collected iron filings because they are magnetic and it distorts the pulse to your electronic engine control module
Look at an ecm print to see if that ecm has 8 injector drivers and only using 2, if so you can repin and use another injector driver. My money is on the coil, TFI module or pick up in distributor though since them faulting was one of the biggest issues with them in mustangs, F series and CVs back in the day
Outstanding, Until out the door. Then, the warranty is void. Lol
There could be an OBDII connector some place.
That would be the fault that came to my mind when you had looked at the other electrical parts. I had the same problem in my car which is an older mercedes. Starts and runs like a dream until the engine warms up, shuts off and after waiting long enough for the engine to cool it starts again and gets a few miles. The spare part cost 7$ and it took 2 days to replace it.
Super 😊😊😊
It’s about i found a genuine guy to call it a philips and not a 4way i love to do all my friends this way i call it Philips too they get puffy and say 4 way you mean i say no Philips 😂😂😂😂😂
Awesome
If the pickup in the distributor is black replace it. It turns to gum and will miss fire Ford had a lot of trouble with these
Hall effect switch
Those Fords are bad about burning up Ignition modules. They will have miss fires. And then when they get hot, they won't run
I wonder what size hammer Matt would have used on that thing
Maybe your friend will spend as much time as you two did on the boat helping on the farm?
First thing I would do is drain the gas and put fresh fuel
By the way, the lake water cooling pump impeller is burned up by now:........
There is a high price to pay between a mechanic and parts changer lol.
Need to put that motor in Matt's 71 ford truck he just got if it wasn't electronic
👍👍
Let me just whip out my ole trusty oscilloscope
Should have checked the gas first boats always have water in the fuel
Them can very temperamental.
So when step one is checking for spark and not having any, then step two is hit the coil and/or distributor with a bfh.....correct????
The over temp cut off was the problem on my boat.
It seems odd to use 8 injectors connected to work like there are only 2. It's much the same as a throttle body system.
Ford's conversion from points to electronic ignition was not as elegant as GM's HEI solution; this problem is more common than it should be with pointless distributor Ford ignition systems.
Absolutely agree,once the distributor was open it all came back to me, this was quite common on these also the side mount modules would overheat and fail 😅
👍👍👍😎☕
Sam isn't the boat to new for you to work on? Just saying you work on mostly old junk, sorry old stuff. LOL I'm just kidding. I had one a year old than that one and I never really had a problem with mine but it had a 350 GM engine in it. I have no suggestion on the Ford engine.
Never own a boat never will i had an uncle who bought my aunt a boat for there wedding anniversary she was a land lover he was a cokehead fisherman who needed a reason to buy a boat . By the way what are the two happiest days of a boat owners life ? The word BOAT is an acronism what does it stand for?
