"Morning everyone.
I have a 95 70 hp (one of two on a seacat)that runs great and starts easy everytime, but whenever I bring up the rpms, it won't go over 1500 on its own, and if I use both motors, it lags behind by about 1000 rpm. I assume that the lag is the other motor actually pushing them both along. The thing is, it stays running smoothly, just won't ramp up. I think it's the fuel pump, but it seems to work proper when I turn it over and crack the line. Is it possible that the pump is just tired and can't keep up at higher rpm? I don't know how similar boats and trucks are (outside of the whole floating on water thing
, but my chevy was doing the same thing untill I changed the fuel pump (200,00 miles, not bad). Any help, even if it's not fuel pump, lol, would be appreciated. Thanks."
