750 Sport Cruiser Prop size

[Turtle]

What the title says. I plan to put a 750 kawi motor in my sc this year and wanted to change the prop. Anyone have any suggestions? Also, do I need to add a pipe for a considerable different between the 650/750 motor?

For an out of the box prop, I think most people would recommend a 9/17 or 10/18.

I am running a Bored 650, with lightened flywheel, mikuni 44, and a coffmans 750 SS pipe/waterbox and am using a 9/17 as my prop......and the thing rips. Most people think I have a 750 in it.

Depends on how you set the 750 up. I have a sp 750, high comp head, single 46, lightweight flywheel, MSD enhancer with retard module, timing advance plate, pump stuffer, coffmans pipe, and coffmans waterbox. After talking with Dave at Impros I ordered a 10/16 hooker. No ride report though, gotta finish her up first and wait for the lakes to thaw.

I don't know how crazy I want to go with the motor. I have a dual manifold and a single but don't want to pull the current motor if it isn't that big of an advantage
