I'm looking to buy a new outboard for my 2001 Nitro NX750 DC. It currently is well underpowered w/ a 75hp Merc. I want to put at least a 115hp Merc on it. I've read a couple of reviews saying that the 115 Optimax falls short on performance. But I know the ProXS has a reputation for being better and faster. So my question is, with prices being the same between the 115 ProXS and a 125 Optimax, for the money, which would be the better buy and performer? Thanks in advance!!!
