I bought a boat, that has a 115 merc on it (1978 model), but is only rated for a 95hp. Here is my delima, I have always been against overpowering boats, but the 115 and the 90 are the exact same motor and weigh exactly the same at 300lbs, but a Johnson of the same year in a 85 hp weighs 312lbs. So if I power down, I gain weight, if I stay the same, I am overpowered. Is this even worth worrying about? What should I do?
