Re: Crusader 502xl ECU.

It was the ECU, so don't let "an expert" bullshit you that the ecu doesn't control fuel pump.

Re: Crusader 502xl ECU.

I did, put two new ones in. Hot wired fuel pump when it wouldn't restart while out on the water, but it's not sending power to the coil either

Thanks

Crusader 502xl ECU.

Re: 502 prop help

Darrin @ Sensenich thought I was a little low on power for the JR or JX, but suggested if I have any disire to increase power close to 500hp + that the JR 3 blade would not hold it and to go with the JX. So JX 3 blade 82" is what I bought, still have rev limiter on engine @ 4,900rpm (2070 prop rpm),...

Rotator flexplate problem

Anybody bought a new Rotator with soft drive for a BBC and had 3 bolts between soft drive and flexplate not line up? My soft drive has two different bolt pattern diameters for some damn reason, 3 one location - 3 another. What'd you do to fix it?

Re: Cadillac 500, torque-prop

Cad Company (Home of the world's fastest Cadillac engines) suggested prop loading the engine at peak torque 3,000 rpm not horsepower 4,500 rpm, which would put me near the 1700-2200 optimal rpm listed for the superwide blades. Currently have a 3 blade 78" Whirlwind model?? similar to a Power shift, ...

Briggs 35hp or 4a084 + belt drives

Thinking about building a mini, which engine would be better the Briggs 35hp or the 4a084. Specs show a 140lb weight saving on the briggs, but is there enough horsepower with the O84 to overcome it? Also who's making belt drives for these engines?


Thanks :florida: :rebel:

Changed the pitch to 16 degrees prop turning 1,500rpm engine 3,750rpm. The weight might be 350-400 maybe less two guys can pick it up plus me 195. It has a rotax 91...

Re: 4a032 prop ???

Engine is level with bottom of boat. It's slow -walking speed. I am going to make it work or blow it up trying. I have a larger carb off a 13hp honda on it, but I think the prop is wrong, too many blades wrong pitch just don't know.
