Re: prop question
You can try the mercury marine prop selector. You will need a stainless prop to get best speed, and likely a bow lifting type if for that bass boat. Maybe a laser 2 or that style of prop and you may have to adjust your motor height. The prop will need to be in perfect condition and your boat should be light as possible, run synthetic gear lube too. Some like to run 4 blades now, they run nice and grab better but can take a couple mph off top speed. You will want to run it close/at the top rpm, Mercs like rpm. I got 43mph gps out of a 85hp force on an open bow bayliner, so unless that is a 22' boat or something you should be going faster I'd think.
