You should try a lipo battery lithium ion that gives you a big boost

It is hard to be specific without knowing what boat, motor, battery pack and
propeller you have. Give us more info.

Generally, weight is your enemy and turning a prop with more pitch and/or
turning it faster will increase the speed. To do so, you may need to
increase the voltage, and/or change to a motor with higher Kv and wattage
ratings (usually a brushless inrunner). When you make such changes, water
cooling of the motor and ESC are generally needed.

FWIW, I have a SuperVee 27 which runs a brushless inrunner motor on 14.4
volts. Stock, I ran in the mid 30 mph range. Changing to a slightly larger
2 blade prop with greater pitch has put it over 40 mph. However, I have had
to make improvements to the stock water cooling as both the motor and ESC
ran hotter.

Bigger is not always better, e.g. while an aggressive pitch and/or bigger and/or more blades does let the boat go faster, chances are your ESC and/or motor will have to cope with heat and you'ld have to combat that. When turning high rpm's small has it's distinct advantages.
Lighter is always better, e.g. weight saving measures do pay up, Lipo's, and everything brushless is lighter and more efficient. Lightness only works against you in speed setup's when you have a lot of wind.
Water is barely compressible, meaning you cannot scale your prop, you can only find the appropiate prop by testing, testing and testing. Hope this helps! Boo

What prop did you put on ?:D
