Have you tried putting someone hanging over the bow - then moving aft? To be honest getting something to plane with 5hp won't be easy.

Hello all, i get the same problem with 2 up and loads of gear can only use half throttle anymore than that and the prop slips and over rev cuts in its a pain in the ass,does anyone think the hydrofoil kit will stop this?

If it doesn't plane, then it'll do exactly what it's doing: top out at certain speed, then you can add a bunch of power for not much gain.

In truth, the same is true even when you do get it to plane; it just happens at a higher speed (takes a ton of additional hp for a few more knots.)
