Location: Grand Rapids MN | Well I moved my motor up two holes and tried it out today. Again it was windy with a chop but I was able to find some cleaner water to test in.
Hole shot- there was a little less bow rise or it didn't stay up as long. Stern seem to lift a little quicker. Acceleration didn't change or didn't seem to. Kind if like the prop wouldnt spool up faster. I'm assuming getting it ported could help with that.
Ride - the ride improved especially at lower speeds compared to the 3 blade and a little over the lower motor mount. I could cut back to 3600rpm and still keep on plan and not porpoise. I even ran slower in the big waves and it did not porpoise and ran a smoother. It was a light load and I have yet to try it out with a heavier load yet. That will be the true test as my other props "weakness" would really show up then.
Performance - I actually lost anywhere from 1-3mph but it still pulled itself up to 40.5mph@6100. At 4600 it ran 27.7. So the lower the rpm seem to have a little more loss.
So I'm thinking I have to go back down one hole. The prop would also blow out a little on turns with any trim. And these were not as tight as yesterday's testing. Over all I'm thinking this prop will meet my needs. Adding an extra blade, more cupping, and even durability with SS without loosing speed isn't to bad and should help when I finally load the boat down. Plus scoring the prop for $150 shipped didn't feel to bad either.
So tonight the motor will come down one hole and back out to the lake tomorrow for testing.... And a little trolling! |
