Are these good compression numbers?

[gabrielh]

Hi I bought a Maxum boat with 1994 Force 120HP engine.
Here are the compression numbers: 115,119,120,120.
Look like it's a little low but are these normal numbers for a 15years old engine? Will I still Be ok for few years of before needing to rebuild top end?

Re: Are these good compression numbers?

They are fine. That said, you still should do a complete decarb to keep the rings free.

For instructions, see the FAQ at the beginning of the maintenance section of the iboats forums.
