If you're running an old style Ranger hull a plate isn't going to do all that much compared to proping your boat correctly. It's too heavy to really give you more then 1-2 mph. I sell to a jackplate mfg and we've played around with these things a ton over the past few years. You may benefit from raising your motor, but find a prop that gets you in the ballpark first and then play with engine height and jackplates.
You NEED a smaller prop. On the old style 620 and a 225 you should be running a 21-23" prop. If you're only getting 4600rpms I'd start at a 19". Remember, lugging an engine can be worse for it then over reving (to a point). I'd try a 19" Rev 4. That's the prop I've been hearing works the best all around on these hulls. If you want the fastest get a Tempest. Although the Rev 4 is going to be faster when hauling a load and when in rough water as the extra blade will stay hooked up and give you more lift.
Drop me a line if you want and I'll help you where I can. |
