Hi Green,

Can you post a few pics of the boat; side-, top-, and rear view?

How many cells does the motor run on now?

What size prop?

This is a large hull, what is it made of?

For this size hull a 700 motor on 12-14 cells would be a better solution, maybe a 800 on 18-20 cells would be even better.

Give us some more info, please.

Regards, Jan.
