Got a 1994 Evinrude on a 16ft Tidecraft bass boat. Not real familiar with OMC's as this is the first one I have really tried to get the best outta it for the size. Right now according to the faria gauges I am using in the boat 44mph is the best at5300rpm's. Has a dang ole stinray stabilizer on it and want to get rid of it cause I know its only a bandaid for a improperly setup boat. The boat is rated for 120hp. I am getting the necessary components to up the ponies on the motor. will actuall have more closer to 140hp when done. Right now (till I do the mods) its got a 13x21 stock stainless on it with the foil. Holeshot is great with one person and fishing load. Am looking for decent holeshot and better topend. Have a friend that will let me borrow 20p raker. Am I going in the right direction. To me the boat is not getting enough total boat lift to run at its potential. If I drill the prop with vent holes will thhis help like it does on Merc props or am I waisting my time. I feel like I should be running in the low to mid fifties with this setup. Right now I am approx.2 1/2" below pad. Should I just raise the motor and try present prop or go ahead and try a different prop. Like I said this is the first OMC that I have tried to optimize. Oh by the way motor doesnt seem to spool up on holrdhot but does launch pretty hard.
