my sw36 screams, sound's like there's a major prob somewhere with yer friend's boat. THe SW comes with a prather 230 and the boat runs great with that. some people say it goes faster with the 235, but the 230 is just fine. Did he break in in properly? THe HSN should be between 2 & 2.5 turns out. Have him start from scratch with the tuning.

here are some pics of me and my buddy's boat. I think they are pretty dang fast...and as far as sitting low in the water at speed, take a look for yourself
(pardon the blurriness, the pictures were taken close to dusk)
