Prop for Evinrude 235

[keith8496]

I have an 84 Evinrude 235. The recomended RPM range for the motor is 4750-5750, with peak horspower at 5250. The prop is a stainless steel 3-blade 14.5x23". The boat is a 1982 Phantom 17' tri-hull Runabout Spirit.<br /><br />The reaches a maximum speed of 55mph at 5000rpm irregarless of weight in the boat. It has some touble pulling up skiers, which is the sole purpose of it's life.<br /><br />My parents, aunt, and uncle claim that when the boat was new, it would pull up teams of skiers. Now the boat is old, and has been given to me. I have been working to restore power lost with age, but i think that the 23" prop might just be too much. Do you think the cost of a new prop is worth the performance i would get back?

Re: Prop for Evinrude 235

For long life youll want to set that motor up at 5800. For pulling skiiers you can set it up (unloaded) higher than that.<br /><br />Yes I'd bet the 23 is a bit much. Regardless of what prop is on there now, at a top rpm of only 5000 the holeshot will be horrible and pulling anything / anybody would be pretty hard.
