Prop suggestion

[glust]

I realize this is a little like asking which oil I should use but here goes. I have a 1984 Suntracker Party Hut '30. Re-powering soon with a 2020 Suzuki 150 hp 4 stroke. Specs for the motor list top RPM at 5500-6000. This boat is big, heavy, and not very hydrodynamic. For these reasons I am not stupid enough to think I'm going to be setting the lake on fire. I would like to get 20-25 mph, maybe tow a tube around gently, not crazy grandkid flipping tubing. Any thought as to pitch or prop? I don't care about holeshot starts. Obviously something that isn't going to blow up my new motor either. Is this possible or am I dreaming? Thanks. Geo

What engine and prop are currently on the toon?

The dealer selling you this motor has no suggestions?

Or prop loan program so you can get the right one?

Thanks for the response, I'm currently running a poorly running at the time johnson 140 crossflow. To be honest I'm not sure of the prop. I'll see if I can find out. Didn't know about a prop loaner program. Place where I'm buying the motor offered a prop for $200 aluminum. I'm assuming they will recommend a proper pitch. at $200 a piece I can't afford to try it till you find it. Not looking for crazy performance I know what boat I have. It would need a JATO unit to truly get up on plane. But I would like 20. maybe 25 mph..

The mercury prop selector should get you in the ball park as long as you know your specs.

Look like 16 pitch is the recommendation. Thanks for all of the help. Be safe

More like a 13 will be closer

That engine has a 2.50gr, so a 16P sounds reasonable as long as total weight is under 4800#. A 13P is recommended with a weight Over 7000#
