I dont want to adjust it, I want to be able to have a manual switch activate the limiter.  I have an older OMC and I'd like to put electronic ignition on it but it has a shift assist module which doesn't allow that, I think there are ways around it none of which work well from what I read.  It works kind of like the MSD limiter, kills ignition to varying cylinders when it's active.  It activates via a switch and is only used at idle rpm when shifting in and out of gear.  The module works with points ignitions, and I was thinking an MSD would help the boat start and run a little better.  I thought there might be a way to hook the switch that activates the module to the RPM limiter on an MSD, or am I dreaming?  Thanks

Thanks, I'll have to look at the module, I'm headed there later to wax it up, make sure it starts and runs for one last river trip.  It's a Cobra, 1990 4.3, it has the original module.  It's a good little boat, holds more folks than my jet does, and my friends wife and kid aren't afraid of it since it's quiet.  The shift assist works, most of the time anyway.  I did some reading and most people seem to have issues when they switched to electronic ignition, I know Delco makes some kit but I'm not spending that kind of money.  I think it could use some help in the ignition department, I was thinking I'd put an MSD box on it and be done but I don't know how it would react if the shift assist kicked in.  Then I got to thinking maybe I could use the MSD rpm function as the shift assist.  I'll get the info on what's there and let you make a recommendation, thanks

Msd makes a dial switch for a rev limiter that hooks up to the system. Works good from what I head. I strongly recomend a rev limiter of some sort. If you pump sucks air it will over rev and damaged the motor as it did mine. in less than a second. Its not a digital 6 is it?
