After 20 years there is bound to be some corrosion and wear - that's why boats with new engines cost more!

Corrosion will be less if it fresh-water cooled. If it has good compression, starts easily, runs and revs freely, doesn't vibrate a lot and doesn't smoke when warm then it's doing its job. Many boats have engines that old (including mine) - age is not the issue but hours (or even lack of them with lots of cold running) and good maintenance in the past.

how do you test compression on a diesel engine - I know its easy on a petrol ???

 

[MoodySabre]

Don't know but I'd ask a garage or marine engineer.

You need to take the injectors out ,not an easy job on these engines as they tend to stick and you need the correct puller,although i removed mine out of my 2001 with a tyre lever,and screw the tester in then turn the engine over on the starter,but why bother if its starting ok and doesnt smoke too much(it will on tickover) i would not worry too much.

My Penta produces a little whitish smoke all the time - warm or cold. Is that very bad?

A little white or grey smoke just shows that you are burning a bit of oil. Inevitable wear in the bores. If it's not major and all works well then I wouldn't lose sleep.
