I have had really bad luck with MSD for too long and decided to switch over to a magneto.
I picked up a Mallory SprintMag 1. It was gone through and recharged about 6 years ago, but only used once to break in a motor before I bought it. I have heard mixed things about the magnets in these things. I heard they will get weak over time, but also heard they only get weak with use. So what is it? I understand the 'rare earth magnets' dont need recharges, but the sprintmag 1's didnt come with those.
Also, what do you guys suggest using for a rev limiter? I run this boat in compjet and its WOT 90% of the time and the pump is unloading often and I bang my 7k chip like a cheap whore. I have found this one (linked below). I like it because they say there is no back firing when youre against the limiter by absorbing the energy of the mag. Anyone have any luck with these?
Second, while trying to fire the boat in the water with the water resistance on the pump....the starter struggles to turn the motor over quick enough to generate enough RPM's to create a spark. Mallory makes a start assist box. Does anyone suggest using this? Will it help with this problem?
Lastly, What is the proper way to time these things? Should I be using a 'buzz box'? or will a timing light be sufficient?
