i am going to turn a boat from brushed to brushless i want a faster boat but not out of control 50 mph tops. it is powered by 2 550 motors and is 3 feet long i would also like to kknow a prop that would work well. the battery is also upgradable. it is currently a 2300 mah nicad

What boat is it?

To get anywhere near 50mph is going to take A LOT of money. What is your budget? Are you planning to run a single motor setup? Is your current setup, surface drive?

its just a cheep boat but i want to turn it into a nice one i am thinking of keeping it under 100$ dollars is it really that expensive? i dodnt think it would be that much what would be an estimate on the price

Anywhere from $175 for a 550 BL motor/esc combo, or if you want a 50mph boat about $400+.
