Prop's performance & trim tabs - need help

[Bushwacker]

Bushwacker borrowed my mirage plus and charted real time real world #s vs the his Rev 4. He killed me in hole shot, min plane , time to plane , mpg, midrange , AND TOP END.

My 4B prop is a 14 1/8 x 20" pitch Michigan Apollo, not a Merc Rev. 4. I was not that impressed with the Mirage +; definitely not as good as the Apollo, especially regarding min planning speed, MPG, and top end, and that was with the vent plugs in. It was even worse with the plugs out. Only problem with the Apollo is it's a little too much prop for my rig - can only turn about 5250 with a moderate load, so I need about 2" less pitch. Will probably try a Powertech once I get some $ saved up. Will post Mirage + vs. Apollo numbers here when I get a chance.

Sandy - another reason my performance numbers look better is the DFI E-Tec vs. older carbed engine! The new DI engines don't dump raw fuel out the exhaust ports, which makes a big difference in MPG, especially at low speed! You're welcome to try my 4B Apollo over at Ft. Desoto. I'll be running my 4B 14x18 aluminum Michigan Vortex, as it'll turn ~ 5600 even with a very heavy load!
