You may want to post this in the prop section of this forum.

The correct prop will let that engine rev to the upper end of the normal operating range. That 150GT's normal operating range is 4500 to 5500, so you'll want it to run flat out (full trim, max throttle) right at 5500. That GT version actually makes close to 165 hp and will still make good hp up to around 5700.
