VX110 Compression Test
I have an opportunity to pick-up a 05 VX110 tomorrow for a very good price. Boat I'm told runs, but will just quit sometimes -- owner frustrated and just wants to get rid of it -- thinks it's an electrical issue, but who knows.
I've rebuilt Yamaha 2-strokes, and Kawasaki 4-strokes, but not the Yamaha's 4-strokes... yet, so I'm lacking a service manual. I searched around, but could not seem to come up with an answer to a couple of basic questions:
a) Compression test expected psi?
b) What size is the spark plug hole? (I can't find my 10mm adapter.)
Can anybody help?

Thanks. Bought a new gauge from Northern Tool with a 10mm adapter. Ended up being 180 psi +/- 2 psi in all four holes. Good.
