So I got a 15 hp evinrude and it has problems getting on plane (really barely wants to) with only one person in it, with some weight at the front it's no problem it planes out fine. So i added some hydrofoils and again with two people in it, one in the back. The issues come when I plane with one person in the boat, it does it more easily now and the speed drastically increased, it's proper on plane and going like nuts but it's gotten crazy unstable, after a few seconds and with increasing speed it feels like the boat just wants to dig into one side, like the foils suddenly create drag on one side.
I'm wondering if that sounds like a set up issue? Like is the engine trimmed wrong? is the engine too high? or are hydrofoils just bad? or the boat?
The trim im using is 3 holes up so the engine is about as horizontal as i can get it and the engine is sitting slightly above the bottom of the hull.
I've been thinking aboout grinding the transom down some to get the engine lower in the water but im worried it'll make the problem worse... anyone got any experience or ideas to share?
