I wanted to make it Stan and was in town actually. Unfortunately I was at the hospital with my mom most of the day. They will be moving her to a recovery home (nursing home) tomorrow on hopes that she will get better. Hopefully soon.
Just not sure it will work well in that short hull. I know @ 12 inches behind the rear tube to the first bulkhead "should" fit but it may not me stable.
Thank you guys for the input. Unfortunately I don't know enough about the engine and I didn't measure the gasket thickness when I installed the button to know what the squish is. Nor do I know the button volume :/
