xr7, I've had two Suzuki 15hp 4-strokes a 99' and currently a 09' both great motors and strong runners. If you look at some of my past post there are some performance testing I did for another member who couldn't make up his mind. My boat is a Lowe 1436 and with myself gas and a small battery I was getting around 27mph GPS. I was going for a good, strong, and light 4-stroke and I have been very happy with my Suzuki. I think the Tohatsu/ Mercs are 10lbs. to 15lbs. heavier. I got mine from a place out west called Porta botes, they sell a folding boat and had the best deal when I was looking. The only problem I encontered was the stock prop was no where near enough pitch, easy fix and now I have a spare or a prop to pull skiers :wink: . Good luck
