yes that was typo, sorry fat fingers and working 3rd shift don't help, ok yes tach would help still figuring how to hook that up?, next that was taken on lake Cumberland at the state dock marina, 1st trip out ran ok considering been sitting for 2 years. Boat had alum. floor with spray foam under it that was completely water logged also 3/4 marine ply wood decks fiberglassed over so extra heavy there. after stripping all that and putting new 3/16 alum decks and and no water logged foam figured I shaved at least 200lbs or more out of it. so that is why I am disappointed in my mph turn out, ok now with the prop only markings I could find on prop is 4674 assuming those are yam. numbers for something. also boat has dumb roll on bed liner on bottom the black in the pic. also have most of it off but still need to paint I know that is creating drag but was figuring I could brake the 30 mark with out freash paint. motor idles rough and needs tune up but does good wot. I do have an exasut leak at the upper gasket not power head but next one down sorry for not knowing correct term. maybe paint ,exaust and prop will cure my blues
