What happened to my thread asking about props and set ups????????????
Quty, nice, are these SST 60 engines? 14 foot tunnel ?? What are the rules you race by? How is your setting for hull??
30-50hp 3cyl yammie, fishing gearfoot, mod to engine is no limit, pump gas, boat length is 10 1/2-12 foot, setting for the hull the highest you can till not lost control.
classed as by number of hp stated by manufacture.
Quty, what props are the 50hp tunnels running? Any insight about the mods you have done on your rig?
myself, push the boat with Ron prop, most r cleaver & few chopper.
mod is outlaw, but none of them using race fuel.
In Formula 50, that was the 3 cylinder STOCK tohatsu, we ran at 725 pounds total. I ran a 12" diameter 22 pitch quicksilver cleaver on long courses and a 12" diameter 20 pitch quicksilver cleaver on short courses. Running correctly, the motor would turn the 22 pitch 7200 rpm and the 20 pitch 7400 rpm. Never broke a single motor part, except for spinning crankshafts the first year. We had water intake covers built that would cover the top half of the water intake on the gearcase. I ran the motor in a marathon, 150+ miles running at 1/2 pound water pressure in the straights and bumping 7 pounds in the turns. The course was 4 miles long.
The first video is the old boat running the 22 pitch.
The second video is the second generation boat, 13mph faster than the old boat.
The third video is the old boat on a short course with the 20 pitch:
