Hi, hopefully you can help me, I recently had to take boat into shop and had new wire harness put in along with a new rev limiter on a merc 125, the problem I have now is the boat gets up to about 5200rpm and the motor shuts down before I get to full throttle, I know the boat use to run at about 5500rpm at full throttle, I thought they put the wrong limiter in but checked my motor and it states that it has a 5250rpm max so they may have the right one in there, just wondering if this is normal for motor to shut down at 5200 with still some throttle left, I also noticed that my voltage gauge on dash reads nothing and was wondering if theres a way to test it or if they may have overlooked another part that should have been replaced and what it may be, I may want to pick it up myself and install it so if anyone thinks they know what it may be please offer advice. Thanks Much I forgot to mention that my battery posts came in contact with my alluminum cover and that is how I fried the harness and limiter to begin with and why I think they may have missed a part that would have an effect on the voltage gauge not working. Thanks again
