Seized 45hp Chrysler

[Steve Mahler]

I just bought a project boat with a Chrysler 45hp where one plug had been left out for 3 yrs, in a salt water environment. eek!

So obviously I cant turn the flywheel by hand; the question is whether I should even bother to try some penetrating oil etc? anyone have any suggestions on chemicals or tactics to try to free it?

Thanks

Re: Seized 45hp Chrysler

You really need to pull the head. If the cylinder has rusted to the point where it is pitted, then the engine needs a re-bore. If it is light rust or corrosion, it is possible that penetrating oil will free it BUT it still needs to be dis-assembled and cleaned.

If it needs a bore job, then with the price of a boring and the price of a piston or two, you are already at the worth of the engine. But if you enjoy working on them, It is easy and quite wrench friendly.

If you don't want to do it, part it out and sell them on ebay.
