I ran the new labbed M+ prop again last night. This time I had a full load of 4 people, 3/4 tank, and full cooler.
At 3000rpm I saw 41mph.
At 4000rpm I saw 62mph
At WOT 4700rpm and 73+mph.
The M+ 3 blade seems to be a little more weight sensitive vs. my B1 4 blade. The boat will porpoise at slower speed so I did use my K-planes to keep her running flat.
With the 3 blade the boat does have a different feel and you do need to "drive" the boat a little more. Once I found the right trim we had a great time cruising for miles at 50 to 60...
Anyone ever try a 3 blade on a 30' Super?
