Boating101 for beginners!!!!! No ONE EXPLAINED THIS after buying that dream boat. BOAT they say 

All good stuff. However, as an M.S., I'd say the MOST important fundamental element in providing reliability in any marine engine must be a gravity fed (self-replenishing or otherwise "day tank") fuel system. It's a legal or insurance requirement on anything bigger than, I think 25m, but really just as important, if not more so, on auxiliary engine installations. In short, if even after weeks of standing, the engine does not start on the very first revolution, then there is a design error in the fuel system. Any churning whatsoever indicates a problem.

THANKYOU,THANKYOU, THANKYOU. Awesome information for me as a hopefully one day boat owner. I subscribed in hopes of seeing more good TECH Tips. truly answer some questions for me as I am a Retired Military Diesel Mech and want to learn these conversions. I believe the Drive train is the most important part of any equipment! Thanks for sharing.

That's all work for my wife. I drive the boat and drink the beer.

1st thing you point out is called the headertank the other thing after the raw oil cooler is called a heat exchanger

Great information thanks so much Paul!

Nice work Captain Paul - And document what has been done and when and what needs to be changed etc Regards

Very well explained.

Informative video, Paul.

Always good info capt, much appreciated. You always stress the need to change out the coolers and heat exchanger when buying a boat with lemans if there isn’t any logs, receipts, documentation which would support recent replacement/ maintenance. I have finally finalized a contract to purchase a 1972 Grand Banks 36 classic woodie🎉🥳🎉🥳 twin Lemans, boat has almost every component replaced, complete rewire, in anticipation of doing the inland passage from Seattle area to Alaska. As soon as I arrive I will order all coolers and a spare, new heat exchangers(send the old ones to radiator shop for spares) hose kits from American diesel and of course lots of zincs, impellers, spare alternator/starter as we plan to live on the hook up in the PNW year round. Again thanks for your maintenance vids.

I appreciate the walkthrough. good stuff!

Great information even for those of us that have gas engines. Preventative maintenance sure saves a lot of headaches.

Love these engine room videos!

Thank you good advice 😊

Have a commercial fishing troller, keel coolers, dry exhaust much simpler and generally trouble free

good stuff as usual thanks

Interesting that in the image of the raw water pump the street ell has "LEE" cast in it's side. There was a brass foundry adjacent to me that for many years made these fitting, the company was Lee Brass named after the two brothers that organized it.

D-series or Dover (Lehman marinized) series Ford engine owners should seriously look into the marine cooling gear made here in NZ. Lose those raw-water pumps for the ones we have been running since the 70's. Replace the horrific combined inlet and exhaust alloy manifold for a galvanised steel version. And our heatexchangers have the separate engine and gearbox coolers bolted to it. So much tidier plumbingwise and cooling is improved. All coolers take the same o-rings, same anodes and all 3 coolers are serviceable on the boat. Plus fit a glass bowl to the first engine mounted fuel filter.

I see you are by looking at a Ford 2700 series diesel engine, a fine unit, re-build many of them

heat exchangers are crazy price nowadays. last raw water pump was nearly 300 and that was a couple years ago.

Header tank n heat exchanger.

New to this, but I'm guessing that the good ground connections to the various coolers are so that the zincs can do their job preventing corrosion? Am I close?

You didn't seem too concerned about the thermostat- I know they're very basic devices that just expand and contract with temperature, but how often, if ever, do you bother with those items (thermostats)?

Are you sponsored by American diesel?

Are you a certified diesel mechanic?

Some excellent information.
