Location: Elk River, Minnesota | Hi again,
Now that you have the boat out, can you take it out for a spin with just you and a light load of gear? The goal being to take it to your full wide open throttle and trim it up to get the numbers, (speed, rpm). Then, trim it down some and make some moderate turns to see if the prop will hold the water. With an aluminum prop, it usually will not hold in a moderate turn unless it is trimmed down fully.
If a prop change is needed, it will always be a compromise of some sort. In most cases, to gain hole-shot, you loose speed and vice versa. The only way to gain in both areas is to have a prop that is steel and vented, but at your HP, you may not find a significant enough increase to warrant the $$ you would need to spend. BUT...a good vented steel prop usually allows a higher motor height off the transom, the blades are thinner and hold water better, which means less trimming.
I'm hoping you can get some solid numbers, and don't be afraid to take the motor all the way to 6000 or higher if it can do so. The motor is designed to go to 6000 for safe use, and can handle higher rpms for short periods of time for testing purposes. This will determine what can be done for a prop change.
