Could battery affect compression numbers?
Just tested compression on both boats during winterization.
Boat 1: 130, 130, 135
Boat 2: 126, 126, 123
Boat 1 has a newer battery, and had no trouble cranking. Boat 2 has an older battery, and sometimes would refuse to turn over after 5 or six cranks (which is about what it took to get the pressure gauge to peak in drown mode).

I believe it will.
Best way to check is to swap the good battery into the other ski.

I figured it might... and was gonna swap the batteries, but was too lazy and tired to do all the unscrewing at the time. Guess that's on the menu for tomorrow.

Your numbers aren't that different, I wouldn't worry anout it unless you have nothing but time on your hands...The biggest thing that effects compression is a bad/cheap gauge

Battery charge would certainly affect your compression numbers, but as Tiny said, I wouldn't worry. They are fine.

It's a decent gauge (OTC 5606). I might swap batteries just to satisfy my curiosity, but based on communal advice, I won't worry.

Yes they do. But as everyone stated you have nothing to worry about.
