Hello-
I recently purchased a used boat - 2002 Monterey with only 35 hrs on
it. Mercruiser 4.3
The compression numbers:
#1 130
#2 185
#3 180
#4 185
#5 180
#6 180

The mechanic who looked at it said that with so few hours on the boat,
its obvious that its sat for a while and that after use - the
compression in #1 would go up.
Should I be concerned? If so, what are the likely reasons for the low
compression in #1?

Thanks!


Yep, but I would have questioned it before I bought it.

A 3+ year old boat with only 35 hours on it? Hmmm.

Why would sitting idle cause it to lose compression in only one cylinder?
