I purchased a used Johnson Evinrude 115 Turbo Jet Powerhead off eBay

I purchased a used Johnson Evinrude 115 Turbo Jet Powerhead off eBay. The seller has an excellent rating and appears to deal in boats that are being parted-out after an insurance claim.

According to the seller, compression is between 130-140 on all cylinders. The boat was parted-out because of vandalism. They claim the engine has not been used in salt water.

I am very familiar with Caveat emptor, and even if the powerhead is misrepresented, the spare parts are worth 2X what I paid.

My question is simple.
Before dropping this powerhead on, what things should I consider changing?
Thermostats? Exhaust Manifold Gaskets? Head Gaskets?

thermostats is all i would do, if compression and spark checked out. you do not say what year or model and what you are going to use it for.

Sorry, I forgot those details.
It is a 1997 115 crossflow bubbleback and it will be replacing a 1996 in a Novurania that has been giving me lots of problems. I'll keep the 1996 and likely rebuild it, but now I'm not in any great rush.
