Hi
I just built a flat bottom boat and it porpisises really bad that i can't even keep it going at full speed before it starts taking in water. It has a inboard motor drive too. Are there any ways that i can stop or reduce this.

My Feedback: (1)

Have you added trim tabs to the hull? Also, if you can, try adjusting the strut.

RVman

I tried trim tabs and they worked good except they slowed the boat down a bit. The hull does have some rocker in it but it's kinda a lot of work to fix that so i'll probably leave it. Btw what is strut?

how big is the boat .what motor and what prop also is the motor at 19% from the transom

The boat is only 15 inches long and 8 wide. The motor is out of an old rc car so i have no clue what kind it is. I got the prop at the lhs and all i know is that it's black and has a 4mm thread. The motor is about 40% from the transom, I wouldn't know why that would matter. This boat was not built from a plan i just copied a full size boat that we have.
