I currently have an 85HP Force O/B on my boat, (what it came with new), it runs great but I was just thinking that if I ever need a new motor what would I get. The boat is rated for max of 90HP, would 5HP make that much of a difference? I like the 4 stroke motors, but they seem huge. Is there a 90HP motor that stands head & shoulders above the rest? I want to go as fast as possible & I know the prop has a lot to do with that, but if the HP isn't getting to the prop, the top of the line prop won't make much of a difference. Just looking for opinions.
