I'm back !!! Motor question.

[Will S.]

I had a medical issue that I didnt think I would ever be boating again. Well, I am lucky & I am back !!!!

Back to looking at used boats again. I have a question.

Will running the ECM diagnostics verify motor hours AND current compression on a 4 stroke ?

Thanks, Will

Don't think there's any way to get a compression number through the computer. Misfires and cylinder contribution, probably.
