Re: This looks like a steal
hate to tell you but you could put 500 hp on the back it won't go a lot faster. A boats hull when designed is made to have so much surface at speed and it's also built to go so fast and they usually won't go alot faster no matter what. My neighbor is a design engineer at Parker and said they make a 18 ft boat that is rated usually for 1 200 hp and it will run 52 MPH and that the coast guard buys the same boats but has them build the boat to hold twin 200's and the 18 ft with twin 200's only ran when tested 54 MPH lol both the 200's were 4 stroke Yamaha's. They tried the same 18 ft too with twin 300 hp Yamaha's and it still only ran 59 MPH all on radar guns too. HP doesn't mean lots of speed.

Re: This looks like a steal
In terms of gas usage balanced against speed what ends up being the best optimal motor for the V20? Probably a 2 stroke 175HP?

Re: This looks like a steal
4 Stroke is 1000% better over 2 stroke but 175 or 200 either are good motors even a 150 is good. More HP won't work as hard so it can use less fuel under a load.

Re: This looks like a steal
Agree on the performance benefits of the 4 stroke, when weight is not an issue. I question if it is worth the upcharge.

Re: This looks like a steal
My Honda is a GREAT motor, so don't get me wrong, but I'm not convinced that across the board 4-stroke is better than 2-stroke...my old 150 Rude had MORE low-end TORQUE and came outta the hole better than same HP Honda...the 4-stroke will come outta the hole, but you gotta FIREWALL it!! Lotta big advantages to 4-stroke, but hole-shots AIN'T one of 'em... ;) :)...

Re: This looks like a steal
Hey any of you guys running a Johnson 115 hp on a V20, the boat I'm getting from Fillet is on a bracket and it looks like my top speed is going to be about 30mph, which I'm comfortable with but am wondering if that is what the rest of you have seen

Re: This looks like a steal
Yeah, Willy, the chop AND the wind that caused it against the top up (like a sail) would impede top-end, but if ya think there's some tunin' and cable probs...geeterdun...you'll be GLAD you did!!... :D...get it ALL!!
