Just a few interesting notes on a Pulsare 2100BR with 300 HPDI. . .
With 12" of setback, 3/4" below the pad, 29P Yamaha T1 prop, ran 85.8.
With 12" of setback, 3/4" below the pad, 29P Tempest Plus prop, ran 85.5.
With 14" of setback, 1/2" below the pad, 29P Yamaha T1 prop, ran 85.4.
I do think it's strange that the boat actually lost speed with 2" extra setback, especially with reports of people gaining speed all the way up to 18". Perhaps it's due to the extra weight of the Yamaha 3.3l way back there. I may have been a little easier to drive, though.
Also, I should note that the Tempest Plus was the fastest out-the-box prop on this boat. The T1 was faster, but it's been worked some.
