I could go out and by a non rev-limiter for 150-200$ but just wanted to know if there was a cheaper way. There has to be something or someone that can shed some more light on this.

I know on yamaha's it's called the "gray wire mod". If you want to take a gamble, cut it and see if it works. You might could solder it back together if it didn't work...
Actually you should be able to pull the wires straight out of the connector without cutting at all. They slide in the rubber multi-pin connectors.

You should be able to find some used electronics somewhere around.
I replaced my powerpack for a $90 cdi unit, I don't think it is that expensive and it seems to work just fine.

Thanks I might try that this weekend, a new cdi is about 150-200$ to get it shipped to canada so if there is a cheaper way like cutting a wire, I'm all for it.

can I ask why people want to go past the rev limiter ?
is the power still going to be in the region past the limiter ?
or is this mainly done when the port timing has been changed, obviously the engine can rev higher, but will it produce the horses once it goes past a certain point.

would it no be simpler to just put on the next pitch prop and keep in original power-band if piston /bore work has not been carried out.......

there is a service bulletin showing where to drill a hole in the pack to disconnect the rev limiter if it has one
or just use an earlier pack as they didnt have limiters

Hey thanks for the tip, I ended up buying a no-rev limiter from CDI. installed it this weekend and it worked great hopefully some more runs this weekend. Thanks everyone for your help.

you can drill it, but if you miss, always used the non rev limiter box my self. stock 75hp omc 49cubes, hp and torque peak together at about 5800rpms, after that torque starts to fade or fall off, hp however holds at 75hp all the way to 7800rpms then hp starts to fade, stock, out the box, gots to go fix boats........

55hp omc head is not a good choice, someone asked
