I'm looking at a boat that has the original Volvo Penta. The last compression test came out 260 on both cylinders. I'm thinking this is low, but don't really know. I would like some help on interpreting these results.
I had a compression test done on my penta md7. The results were similar but I had a split of 15psi between cylinders(250-265ish). It ran for years without issues till I pulled it for a new beta13.
Thinking about it now I should of installed a bracket with an outboard motor. It would of been a better option for the type of sailing I do.
I had a fellow sailor recommended restore. It's an oil that helps with compression issues. check it out or maybe somebody can comment on it. Engine Restorer
I did a compression test on my md6 a long time ago (7 yrs?).
I think I had a conversation about it on here.
