Compression Question

Hi all,
I am looking at buying a 2008 Whittley with a Suzuki 115 outboard
On the report it shows the compression's as 200 200 195 and 205.
My question is should I be concerned about the last two readings




Thanks

Re: Compression Question

Those reading sound fine.

A slight deviation is Ok - many things affect reading.


To test fully two readings should normally be taken - a Wet and a Dry reading.

Re: Compression Question

I would not be very concerned until there is around 10% differential between cylinders, but even 1 cylinder with 10% would have me looking to tear it down for rings.
