[QUOTE="Johny25, post: 328113, member: 7791"] You know I went back and looked at your boat in the pic and it looks like you have a long shaft motor? And your boat looks like it is made for a short shaft? If this is the case a jack plate would give you some more speed also. Now to the 20/25hp.........You are going to obviously be over coast guard regs by putting anything over a 15hp on it and liability wise I would not advise doing so. But now that I have said that.........I would go with the 25 or even 30hp if I were to do it. Most 20hp weigh as much as 30hp and are usually made from the same block. You are at minimum looking at adding 40-50lbs onto your transom by stepping up to a 20-25-30hp motor. Would have to go with a 2 stroke to keep weight down also. Not saying to do it but that little boat would FLY! :mrgreen: should be able to attain speeds of 32-36mph possibly more depending on HP and setup. That is scary fast in a 12' tin with tiller control trust me :shock: [/QUOTE]
