I have a 16ft lowe line v bottom with a 40hp merc. I just finished rebuilding the motor and have decked the boat, carpeted it all, and built a side console. I have taken it to the lake twice and run it, and it has scared me a little bit with its handling at higher speeds. Higher speeds meaning at WOT, which is about 20mph. The motor has a Doel-Fin hydrofoil already on it, and I do think it helps with stabilization at lower speeds, so I will probably leave it on. When I am cruising around on the lake the boat leans quite a bit especially on turns, and it sharply shifts when weight barely moves on the bow. Its a bit unnerving when it does this, especially to passengers. I have been looking into these SX Smart Tabs and they seem like they be the solution, but I am not sure. Any advice is appreciated. Also, if anyone has experience with those trim tabs on a boat similar to mine, that would be awesome. Thanks. Mac.
