compression on 2016 yamaha LF200XCA- Is this high?

[gp32765]

I have a 2016 with twin yamahas with 230 hours im thinking about buying.
All cylinders came back with psi around 260.
Seems high? Why so high? What is the cause?
This is on all the engines and all the cylinders.

Try a different compression gauge.

That is the second one

Not being a wise ass but, where did you get the comp gauge?

The marina did the check for me

OK, My guess is the engine was put up for the winter and oiled well. Oil in the cylinders will spike compression. I would run the engine, get it up to temp and the numbers will probably change.

Run seafoam or ringsfree and check again

Like Chris said, warm up the engine first. Also, my service manual says to fully open the throttle as well when you crank it.
