Full attention

Well the Sunkist scared the hell out of me this weekend. The motor sputtered twice and went dead under full power all in about a millisecond. Those of you that know Rufus' old boat know what happened next. Yes ole liveries went left and right up on to a grassy bank about 30 to forty feet. Luckily my passenger and I were not injured. The boat hit the only grassy bank on lake Greeson I think. Thanks to all of you guys that warned me before hand about my boat hooking, I had time to tell my passenger to hold on "were about to go for a ride". All is well with litle to no boat damage. I just need some insight as to why it might have died like that. We pulled it off the bank I cleaned the intake out and it fired right up and I drove it to Kirby from rock creek, with no problems or shut down.

I will talk to chop. I was just lucky to go on the bank where I did. I'm also going to look into some things this week. I still haven't put an alternator on the boat only because I've been working long hours and haven't had time. I'm wondering if low voltage could cause it to quit firing at full throttle but keep in mind it cranked right up anr ran fine at slow speeds after.what im wondering does it take a full 12 volts to run the msd at full throttle but will crank and run at cruising speeds with quite a bit less?

yes. could be low voltage. the higher you rev the more power they take.What was battery voltage?

. Don't know didn't check it. It was at the end of the day after running the bildge alot and several cranks. I'm sure it was way less than fully charged, but would still crank a 14.5 to 1 engine .

The ol tow boat did the same thing to me. Going across the lake yesterday about 3500 rpm it sputtered a couple times and completely shut off. I have a toggle switch on mine and a push button. The bottom wire on the toggle switch is loose and killed the ignition. Reach my hand under there and hold it down while driving. A country boy can survive!

My MSD shut down like your saying luckily the boat stayed straight changed the box to a digital 6 and then found out I lost my ground

I'd be having the distributor and coil spun on a ignition Dyno and see of anything is breaking down .....
