test it under load on the water and at different rpm then you get all the demons and real symptoms and errors from the engine. What they show is only the first test😂

well thanks for the explanation, I replace the water pump in that 3.7 and just hook up the engine with water to heat exchanger and overheating problems, got be that thermostat or air in the system, The engine purrs. but I got find why that closed system is over heating.

Been slowly fixing up a old 88 bluewater cuddy

Good old ford 460 1/2 most 1974 ford 460 parts will fit like head gaskets heads engine parts like valves lifters and aluminum heads Some guys even put them in cars the Chevy th 350 th400 trans will fit it with a Chevy bell housing be nice in a mini cooper the biggest 4cy u can get with 250lb of tourqe

Good job again Keith. Going to do my pump now that you have done this for us. Were you able to locate gauze fo the other tube?

Keep me posted 👍

Brain picking time please! Engine started easily and ran smoothly after new points and condenser. However it has now started running rough on start-up, but then would run OK after a couple of 3/4 throttle revs, nice and smooth. Thought it could be dirt in the carb so stripped and carb repair kit installed - gaskets, needle valve, mixture screw, accelerator pump plunger. It wouldn't start so put the old parts back. Still wont start. Have you any ideas why it started running rough but cleared after a couple of revs and what to check for no start please. Thanks in advance. Regards.

I use to play a DK Computer Game called Castle Explorer. 1996.

Oh yeah. Another thing! The Medievals were Police-less. No Constabulary either. No Emergency Services to help you with situations back then, Centuries Ago. Can you imagine that?! No 999 Number Call.

I'd never even noticed it! Thanks for pointing this out, could save a breakdown at sea. Regards.

Beautifully explained, now I understand how it actually works and it is obviously worth checking. What seals the end plates to prevent leakage - I didn't see any gasket? Many thanks for posting, your videos are really helping me to understand my engine.

Oh yeah! Ive just remembered. There was so little beauty in the Medievals Periods. So much Suffering! How ever could you Survive yourself in a Century Period Time like those?!

Great video as always Keith. I've got mine running and it is smooth and revs no probs, but I am getting black exhaust smoke. Oil is uncontaminated, water pumps OK. Any ideas please?

Big job mate to restore it.. I had the same Signature hull years ago it was called a 2250L, it had a 200ph Merc Black Max when I bought it, I blew that up, and then put a 200 four stroke Zuki on it. They are a good bay boat, not really suited for offshore, big swell.. Funnily enough it was nearly a 23ft boat but I thought it only had the capability of a 19ft boat, as it use porpoise badly. They are extremely light in the front bow section, throw in a heap of anchor chain, that will accommodate that lol.. Or trim tabs will fix also. I'll keep an eye on your restoration. Cheers 🍻

Another very informative vid. Thanks.

I have a 78 searay sedan bridge with 2 mercruiser 470s. Upgrade to alternator, 4 barrel carb and 4” manifolds

Thanks Daniel

Once again great informational and how to do it. Inspiration to people who do this work them selves.

keith, I just rebuilt the same motor! Got it on a Mirage Cuddy Cabin Boat. Let me know if you have any questions.

You sure love Nipping, you little nipping nipper

I now have a Facebook page for this project called Keith’s Broken Boats. So if you want to contact me you can.

Hey Keith I would like to echo the others in as your videos were informative. I have recently bought a boat with a 3.7 in it and all I am keeping is the engine. May not even keep the exhaust on the engine either. I am going to try to swap it into an old jeep I have. You would be welcome to the rest of it, outdrive prop gimbal all the "boat stuff" Shipping might be prohibitive??? as I live in the US, Oklahoma to be exact. I dont know much on how you would contact me. let me know on here if I need to do something else. Keep up the good work. I enjoy your content. Thanks.

Dude thank you. so glad i found your videos im currently trying to fix a fuel leak where the hard line goes into the carb

I just got a 19ft bluewater with this 3.7l 470

This is a bummer Keith. I have met with similar from time to time, frustrating to say the very least.. These 3.7 vids of yours have given inspiration to work on mine. Have a Beer about it and try to relax. Please PM with an address as I wish to send you something in the mail.

Keith, don't give up. You inspired me with my project. I've got a 1979 boat with the same engine. I've done a total engine brake down because it was all locked up due to water damage. You have really helped me. Remember where there is will there is a way. I'm pretty sure that most all of your followers are with me on this. Things have a way of working out when you believe in something. We're counting on you my friend.

Your videos have helped so much with my rebuild of my engine. Happy to pay it forward. I've got some of the parts you need. Like for sure the power steering. All you got to take care of is the shipping. Let me see what I have when I get home find a way to contact me.

Congrats Keith! I never doubted for a moment it wouldn't start!!

Well done Keith👍, good to see you’ve got the engine going. We can’t wait to see the boat on the water. I’m also pleased to see you had adult supervision while you were doing it - even if he didn’t get his hands out of his pockets 😊

Keith, where did you get your gaskets from please. Thanks.

I have the same motor also. Overheated by the previous owner so these vids are invaluable. Many thanks for posting.

Never in doubt you would get it started Keith! Well done 🎉

Just bought an old(ish) Fletcher 17gts with this engine, which had overheated. Your vids will help me to analyses and hopefully get it going again. Great explanations, many thanks.

Keith, which fuel do you use, E5 or E10 or doesn't it matter? Could you also tell me please what grade of oil you use - We have just bought a fletcher 17 GTS with this engine. Needs a lot of TLC - it overheated but not seized so you vids are really welcome. Many thanks.

Brilliant, well done.

Hi Kieth, I've followed you every step of the way and shared your tears and joy. What a fantastic achievement, I thought that this day would never come. The big Merc lives again to cruise the ocean waves once again. Well done my friend, now onwards and upwards with the rest of the restoration. I'd love to volunteer for the maiden voyage lol

This is brilliant. We've done sailing, we've done UK canals and now in our twilight years we've bought a Fletcher 17 GTS with this engine. So these videos will provide the knowledge and guidance I need to fault find and refurbish the motor. Thank you very much Keith. Regards

Great camp set up 👍

I know that wall tents and umbrella tents were common in the middle ages but I was not aware bell back wedge tents were used as well. We use then for 18th century/ American Revolutionary War reenactments.

Well done Keith, what a journey I've enjoyed your videos and listening about it in the yard. Can't wait to see the video of it in the boat.👍

congrats sir. thanks for all the help. bought a boat with this engine and told it had a fuel issue. found hole in piston and your vids are helping me reassemble after my teardown

Congrats!! I have the exact same engine and i'm working on it. Just got the rod bearings changed

Congratulations keithhave really enjoyed your build along. Will ook forward to see it on the water.

Hello bud..Well congrats to you on getting this bad beast up and running. You have spent so much man hours on it to this video of the engine running...Its near the time for the restore..That does sound sweet..Fair play chap...

Nice to hear the roar of that engine! Nicely done.

How many times can you do that to the valve seat before it's too worn?

Once again Keith. Great and informative information. An inspiration to do it yourselfers.

Awesome video. Well done! Thanks for this!

I am also trying to find the proper torque for the flywheel bolts. 50lb feels good but 75 seems way to tight
