Hi, first time post here.
I recently purchased a 2000 Bayliner Cuddy with fresh water cooler 5.0 Merc. Engine runs good, did sea trial etc before purchase. Took boat into local marine shop to get winterized/check over. Had them do a compression check, got a call from the mechanic asking if I planned on keeping the hot or selling it, as two cylinders were low.
The readings are :
180/150/180/150 175/170/175/160
Is this something to be concerned about?? 150 sounds like a decent compression to me. I know it’s more than 10% variance, think it’s like 16% between high and low cylinders, but I don’t know, doesn’t sound terrible to me. What do you guys think? Would you be concerned with these numbers at all? Does it warrant further investigation?
Cheers
