I have an Etec 150HO on my 22' Hurricane Fundeck. I only get about 4800-5000rpm when trimmed down but get 5100-5300 when I trim it about half way up. Should I look at changing the prop to get higher rpm? Will it result in higher top speed? Will I lose or gain torque when pulling a skiier up?
If you are pulling skiers, you want a higher rpm, near the redline for best acceleration. The redline depends on your model number. Please post it here.
To find out if your prop is correct, trim the motor up slowly until it loses its grip, then trim down until you reach the best speed. Record that rpm and speed and trim position.
For pulling up skiers, trim the motor all the way in when you start.
Do you mean 5250 rpm?
What propeller make , model, and pitch ?
Remove the propnut and spacer to see the size stamped on the inner hub.
try the 15" Viper prop. You may be able to raise the motor one our two mounting holes for even better performance.
Make sure that your tachometer is accurate as many are not. You dealer can easily check it with his laptop.
