Compression Test

[JamesC]

I posted to a topic in the wrong part of the forums so I'll post this here because its more appropriate.

I am looking at buying a 96 Searayder and I would like to do a compression test on it. My question is what size are the spark plugs on these engine? is it the standard 5/8" spark plug with a 14mm thread like on most car engines or is it a different size plug I am a mechanic but I have very little boat experience. I tried to look at the manuals but I am not a premium member yet. Im planning to drive a couple hours to look at the boat this weekend so I want to make sure I have the right adapter for the spark plug threads its 120 hp engine

Due to the fact that you aren't buying a Seadoo product this question might not be able to be answered on this form. You might have to try a Searayder forum. Someone here might have your answer though.

I believe that is the correct size...the manuals here are all seadoo not Searayder...that's Searay, and they discontinued that model years ago. That's why I didn't buy one when I was looking around. You can't get parts anywhere.

Thanks for the reply I don't know why I thought it was made by seadoo.
