johnson 150 parker 21 dv prop question.

[Dascyllus]

Does anyone have this setup? I have 1996 johnson ocean pro 150 on my 96 parker 21 deep v. recently bought it used and need to prop it. Any suggestions for aluminum prop size? engine was just completely remanufactured because it has been overproped.

Thanks,
-J

For that heavy a boat with only 150 ponies I'd go with a premium SS blade. I would not put an aluminum prop on that rig.

You also need to find out, from the OEM specs, whether that is a 5500 or 6000 RPM at WOT motor. Then, with a clean or freshly painted running bottom, in cooler Spring or Fall weather, you want to turn no more than 300 RPMs off max, 200 preferred, even if this means you need to send the prop out to be tweaked.

Normally I'd expect such a rig to wear a 17" pitch prop, but where that's low HP for that hull, you may need to go lower. If you pay the shipping (both ways if needed) I have a 3-blade 15" SS Stiletto you could try. Check Overtons.com, they sell for $330 or so. $125 if you want it.
