As I posted on a previous post I have a really nice homemade 18hp surface drive (I know a lot people say stay away from the homemade stuff but this one is of factory built quality from a reputable machinist in my area). I just bought the motor and haven't had a chance to run it yet but I was wandering on a 15' v-hull boat (really light) what kind of mph and im looking to get out of this motor?

Ok......... well not arguing your reply and I honestly appreciate your input. The guy I bought it from which is a pretty straight up guy was saying 15-25 depending on the boat. A friend of mine has a 15hp go-devil and he can run 12-15mph. Just wandering why do you say 6mph??

youll get more than 6mph out of it, provided the pulley ratio is set right for that hp motor and everything else is good. i have a 7hp sd on a 1436 jon boat and get 15mph with dog and myself. i would think that you should be able to get close to 20mph. let us know how it does?

thanks for the advice and definatly will Im offshore now but hope to get it on the boat and lined out when I get home if I can figure out the prop angle I need to set the motor at...

Well I lucked up and got me 1548 alweld. I think its going to be little heavier than that v-hull I had but im hoping with a flat wide bottom ill be up out of the water more.

Thats cool.Are the Alweld smooth or ribbed on the bottom?I'm running a 15-48 G-3 with a mod v front and a 23hp Dixie SD on the back of it.Haven't ran smooth water in it yet but get 24-25 mph in the chop.
Good luck let us know how the 18 pushes it.
