Re: is a 115hp yamaha enough?
A close friend and long time fishing companion of myself and my father had a 21' starcraft center console from the mid 80s. He had a 70hp yamaha and a 9.9hp 4stroke yamaha high thrust kicker. He had no problem hitting 30+ mph with her. It was a great hole shot boat and could take a pounding to boot. That 70hp yammy lasted almost 15 hard fishing seasons. He sold the boat to a friend of ours and the powerhead finally went on the 70.<br /><br />This is a similar boat to yours, 1 foot shouldnt be all that much of a difference. I could see your boat doing well with a 100hp even...It's nice to have that power there and not have to WOT the engine to get the speed you want, but a smaller block comsumes less too... Aluminum doesn't take a whole lot of ponies to get up and go.
