I have a triton bass boat 21ft with a mercury 225 carb 3.0L, 5in jack plate, 25p fury prop , right now motor is completely stock, lower unit gear ratio is 1:75. Im running an average of 74-76mph best ever achieved is 78.6 and speed was taken off of two separate gps units, iv slightly sanded the pad in x motions to trap air under the pad, added 1-2 mph, I am putting a 4 inch extension on the jack plate soon to increase the setback but Im not sure what I can do as far as gaining more hp there are so many tuners and velocity stacks ect... out there and im not sure what works and what will cook my pistons, any advise is appreciated, I would like to be able to break that 80mph barrier.
