Diesel Air Intake

Remembering that air is a primary mixture for diesel operation, has anyone noticed that there is no ducting of air to the engine on the 37's? I have had no problems with engine performance just wondering where the fresh air was coming into the engine compartment.

Thanks George

31's have ducting to engine compartment, so it must be a model
dependent thing.

On the PSC '34, we can flip open the little engine compartment lid, just under the companionway ladder. From pictures I have of the '37, it looks like you should be able to do the same if you'd like to give your engine a little more air to breath. If you're pushing the engine hard and/or it's particularly hot, it might be worth doing.

We had vents on the upper surface of our stbd coaming box, if I recall correctly.

On another subject I was looking at a 1994 PSC 34 that appears to be in mint condition except the engine, 44JH2E, has 4195 hours on it. Any comments? The Dealer says the owner has records of engine maintenance done.

As part of the standard boat inspection I would have a mechanic check it out (check compression, etc). General rule is that a well maintained diesel engine can go 8000 hours without a major overhaul.
