I just rebuilt my motor and my 28 Bravo 1 looks like it's going to be a little small. I still need to finish tuning the carb and final timing, but I'm already running 5600 with a full tank and 4 adults. My question is, do I select a prop that will get my motor to run at peak HP or at peak torque or somewhere else? I'm confident that when I have every thing rung out I will be hitting the 6k rev limiter pretty hard. I have a Velocity 280 that runs pretty light in the stern so I don't want a Hydro-Motive. My current speed is 86 with a 1.5 B1 outdrive.

Prop it for 800-1200rpms above peak torque most likely. It somewhat depends on where the torque starts falling off and how fast.

So far things look to be working well and hooking up well with 11% slip.

To answer your question, in my opinion, prop through the torq and just to/before the max HP.

Let me know if we can help.
