When I run my 80 lbs transom mount Traxiss at 100% power I always blow the fuse. Very frustrating… What is the best way to fix this issue? This is on a 4 year old Alumacraft Dominator 175 with all the factory wiring.
I believe I am using the right term of “fuse”. Under the red connecter cap at the battery terminal there is a grey “fuse”. When it blows a little black button pops out. I reset the button and everything runs normal as long as i stay around 75% thrust.
Thanks!
It is a breaker that is popping. You most likely have a short in the circut.
What size is the breaker? For an 80lb. motor you should be running a 60 amp breaker, my guess is you only have a 50 amp. That would be the first thing to look at, let us know what you have and we can go from there.

Good call. I was assuming the correct size was in place.

That is the problem right there, I would bet money on it. Cheap to try a new one, I think they are about $8 at the hardware store here.
So I checked the breaker, for the transom it is listed as a 40a, interestingly the one for the bow is listed as a 50a. Can I assume that going to an 80 amp on both is safe? Im going to put a Terrova 80lbs on the bow and I thought I read somewhere you needed more amps to run that motor. Thanks!!!
60amp.
You should use the rated amp breaker for each motor from each owners manual. 2 breakers, not one. If you exceed the amp rating on the 60 amp motor, it will have fried before the breaker pops at 80 amps Don’t use one 80 amp breaker.
I was taught never to assume, cuz it makes an [censored] out of U and me.

You only need one breaker, it is supposed to go on the red lead coming off of the motor not back by the battery. Dont assume it goes by the battery 
sorry I couldn’t resist.
In all honesty it doesnt matter where you put it as long as it is on the hard line, not on each lead going to the battery.
You need only one breaker but it needs to go on the battery at the B+ post. The purpose of a breaker or fuse is to protect the circuit and the motor. If you short out the wire between the motor and battery you don’t want your battery discharging to ground through the wire that is routed through your boat. Look at your car the fuse box is close to the battery. You should be running a 60 AMP breaker.
Check to make sure your terminals are “Clean” if there is any corrosion on them it will cause the little gray breakers to trip ….. 
Fleet Farm sells some self resetting ckt breakers in the boating isle. They bold to the battery terminal. The rule of thumb used to be about 1 amp per pound of thrust. This may have changed with more efficient motors? Make sure your wire gauge is large enough to handle that current and no longer than necessary. Factory wiring may not be large enough to handle all that current.
