I've currently got a 15' ProCraft with a 90hp Rude on her. It's rated for 100hp. I was thinking of doing this - just a thought at this stage.......but tell me what you think?? I was thinking of finding a 115 or even a 140 hp motor and slapping that on her! I could get some 100hp stickers made up and nobody would be the wiser. I realize this isn't perfectly "legal" but I don't think anyone would notice.....especially since newer motors are smaller than they used to be. Correct me if I'm wrong, but the rating is not based on Coast Guard standards or anything, it's the manufacturer' recommendation, right?? So are these recommendations based on weight of the motor on the transom - or maybe the force on the transom under power? I can run high 40's/low 50's now depending on load........I can't imagine what she'd do with a 140 on her! I was thinking 70's????? Has anyone else ever done this?? The hardest part would be getting the wife's permission - which is prolly the deal killer. What's the resale factor on my old 90 rude? It's a 1983 model, runs like a champ........and I was thinking what would my payback be on it?? Trying to justify this to her is going to be darn near impossible. HAHA! What do you think the cost of a nice, used 140(ish) HP would be and what could I get out of my 90hp???? Thanks!
