We run a 1.22 gear 30 pitch prop imco sc but we run alot more hp. You may be better running a 1.36 with your new motor combo. Big props put alot of load on your drive.

Only 3, 27 ICC's on the board?Jeremy i look at that speedo of yours and feel the bowrider is scrubbing off about 25mph.I use a 26 bravo now at 5200.Going to a 30 should drag the rpm's way back,shouldn't it.The 30's bolted up,awaiting testing.Marty so definetly 1:5 gears and not 1:36?I should have between 800-900HP with the big motor.Carl.

Just got my 27 on the water, 850 + hp X is even with the sponsons spinning a stock 32 bravo-1 best GPS has been 112 at 5300.

Oh ya IMCO drive with 1.36.

Wow 5% slip pretty good wonder what it would run with a labbed or trued prop with a little more pitch?

Amazing,gained 10mph with the standard 30 Bravo over the 26.RPM 4900.Starting to get a little more like it.Once i switch to the 2"shorty might get a little more??So i moved up 4" of pitch,gained 10mph and lost 300RPM.So different to a vee.Hey CAT i should end up with something like your package.Marty what do you think about 1:36 compared to the 1:50?If i go 1:50 i might run out of prop.Hey Jeremy old buddy,don't know if that 87 is going to cut it with the other 27 guys on the board,might need to Procharge or something :-)

27 Daytona in Australia.

I agree, it was planned to have a whipple one day thus the boost gauge on the dash, just never made it.

Only having a go at you mate.Your still faster than me.

only for now. It seams more and more people with a 27 daytona has big power like b boaters. My pocket book stops well before the price of big power.
