Will update as I go so others don’t have to go through this.
Suzuki 4 blade 28p (made by Powertech?) 65 mph loaded if I remember correctly. IDK for sure since I took it off before really checking. 70mph unloaded. RPM unknown since gauge was not working at that time. Moderate lift. Fast out of hole.
Solas Scorpion 27p 6100 RPM 71mph good lift. Just ok out of hole.
Powertech BRV-3 28p 6100rpm 65 mph would not lift bow at all. Slow out of hole.
Going to put Solas back on and send back Powertech so they can make adjustments or a different prop or whatever to get me closer to the Solas performance.
Hoping to find the right combo that gets me a little more speed/performance. Will update as soon as I try something else.
Update:
Solas Scorpion 28. Much faster at lower RPM. Takes longer to get higher RPM. Got 6000 RPM 71mph. Played around with the jackplate between 0 and 3. 0 is very mushy and 3 is rather stiff. Trim hard to know exactly with Suzuki digital gauge. Just have to go by feel. I feel if the Scorpion came in a 29 or 30 I could get even more but it doesn't Hole shot would suck but the motor could handle it just fine I think.
Update: Solas Scorpion 28. After running it hard 6 days on the Delta here are the results. I was getting 73mph at 5900 RPM. 71 Tournament load. If I had a longer stretch and less wind and waves and cooler weather (90's) I am sure I could get more out of it loaded and even more alone with a light load. At 73 there was maybe a tiny bit of chine walk. Honestly idk as my brain/muscle memory just auto corrects this and I don't notice it much anymore.
This prop also handled very rough water well.
