Good to know.. It has excellent compression and not a scratch in the sleeve or piston. The bearing seems tight and there is no rust or corrosion in the engine.. I'm thinking I'll refurb this one and pit on a 20 series 3pt airboat and the k&b .65 I got I'll put on either a flat bottom or a 60 series 3pt. I guess it wasnt a bad deal considering the two engines were free..

Thanks for all of your help, guys... Looks like I should be able to swing a 10x6 prop at 12,800rpm give or take... Are these Fox's similar to K&B in they are slower spinning engines?
