I have an 1994 ranger cherokee 107 aluminum 17.5 foot bass boat with a 94 60hp johnson outboard. I bought back in Feb. of 2011. I love the boat but I want to up grade the outboards. I want to max it out to its recommened 75 but I dont know if I can put a 75 merc. optimax on it and it still be safe. Anyone have any opinions on this? I am also recarpeting the boat even though it doesnt need it and I am looking to have it repainted.
