Would you try to rebuild a marine engine that has only 75 hrs on it but sat for 2 yrs, but it cranked easily?
Engine is 350 crate motor, ran for 2 minutes to check it, need to drain oil and gas before running again. In 28ft wood cruiser

Not if it appeared to be working properly.

If you are in doubt, have it compression tested. If the compression on each cylinder is fine, I wouldn’t rebuild it.
If it checks out, after you change the oil, run it a while and change the oil and filter again. You need to get all the rust out, if any has formed. Better safe than sorry.

As the previous poster said, if the engine has nothing wrong with it there’s no reason to rebuild it.
On the other hand, testing the compression, looking at the cylinders with a borescope, looking at the PCV filter for signs of excessive blowby, checking for rust in the oil… these are all good things and might tell you just how closely you’ll need to watch it later.

No need the engine is fresh just change the fluids and put in some carb cleaner in the gas to keep the fuel jets clean and maybe change the fuel filter as well should be fine.

brianL is right. the worst it can be is a stuck ring or two….which i doubt. choking it out with powertune by Mercury a time or two will take care of stuck rings most of the time. good luck.
