27.7mph @ 3800
42mph @ 5600
30mph @ 4100
25.5mph @ 3600
20 mph beam wind, same rpm/speed running both ways up and down the river.
Load was 55 gallons fuel, 2 guys, full live well (about 360 pounds), with empty baitwell the speeds/rpm were the same but the hole shot was even worse. A little trim tab solved this.
5600 was as much as I could get without trimming the motor up too much. Prop really grabbed well, no problem keeping on plane at low speed, felt great. 3800 to 4000 seemed to be a really nice cruise. Hole shot was terrible but I expected as much.
AND
F225 manual says under a full load, the RPMs need to be in the upper half of the full throttle range. Full throttle range is 5000 to 6000. I was not at a full load and barely getting into the upper half of full range (5600).
I just wish they made an 18 pitch !
