Hydrofoil?

I was just out with my Terhi Micro Fun 10 foot with my Honda 15hp four stroke.
The boat is 10 feet long and weights about 220. It was very heavy in the back
and it took ages for the boat to plane, since I weight about 220 as well I was
thinking of installing a hydrofoil on the engine.

Whats your thoughts about that?

There was a similar post in the last two months. I can not find it at this time.

Basically, move as much forward as you can...fuel tank, gear etc.

Lower the tilt pin to a lower hole if you have not tried it already. The final position of the tilt pin is something that you will just have to play with to meet take off and cruising.

A whale tail will help get your back end up quicker. A small pitch prop might help. A four bladed prop will help get the back end up but you sometimes loose a little on top end.

Just make one change at a time. If you go with all the above at the same time, you will get up on plane but you may then overrev.

Those Smart Tabs look like a pretty cool tool. Their video said 14 foot and up though.

Like Mike said, getting the weight forward is going to be the key, especially on a 10 foot hull. You should try to sit as far forward as possible since your body weight rivals that of the outboard itself and you just don't have enough boat sticking out in front of you to act as a lever.

I use a tiller/throttle control extension to allow me to operate the 12' boats I work on from the center seat bench instead of the rear. These boat's are powered by 8 hp Hondas and I weigh more than you do. With this set up, they "pop" right up on plane and will do close to 20 mph on smooth water.

If you drove your 10 footer this way, with that 15, I bet it would plane instantly and be scary fast. Always wear the kill lanyard.
 
I have a 12 ft. Duro Boat, 268lbs. with a 55lb thrust electric motor BF100 engine lowered to the last pin, two 68lb batteries right in the bow.
Even with the 3 gallon gas tank up front of the boat it squatted down into the water with the bow in the air.
I had the angle of the stock three bladed prop. changed, still no different, the answer came when I installed cutting boards onto the cavitation plates of the outboard, adding 12 inches to the width, this solved the problem, so well I moved the outboard angle up one pin hole, planes across the water perfectly.
Maybe you prefer prettier alternatives to the cutting board idea but this works for me.
