Wondering if anyony one knows if 120 lbs compression in a 1991 440 jet ski is about right or should i considder rebuilding? thanks

 

Hi and welcome to KF.i don't know the anser to ur question but there is a jet ski section in here try posting in there.

 

Welcome to the forums...

The 440 was a popular dude back in the day... 120 is good, if that's what you have in each cylinder. Now if one cylinder is say 105, and the other is 120, then it is time for a rebuild.

Are you having a problem with the ski?

 

Hmmm. I think that was the first Jet-ski I ever rode!

 

i don't but welcome anyway..... lol lol lol
