I have twins Starbard motor after running one minute I lose fire and the motor cuts off

BOAT HAS MSD BOXS AND DISTRIBUTORS AND # 2 MSD LARGE BLUE COILS

Changed coils no difference

you wait about 3 to 5 minutes and the motor starts up and does the same thing

any advice

sounds like the msd box.... easy test....switch the boxes and see if the other motor cuts off....you could do the same with the coils.....its SO NICE to have twins.....good luck!!

ive had SO MANY problems with msd stuff.... i drag raced for many years, all i will use is mallory intermetent problems blow

already switched coils no difference going to try boes in morning what about the pic up and module inside the msd distributor

Not so sure about the pickup...it is a possibility, as it does tell the coil to fire, but I've never personally heard of an intermitent problem with those... The fact that it starts back up and repeats says computer control mod inside msd box...

Try to wiggle the pink wire that comes off the Dist. to the coil . We just had to replace ours on the 42.

i agree,sounds like a bad box,but the pickup is cheap and easy to replace.i would change it anyway,then you eliminate the question of it being bad.

Thanks Guys It Was The Msd Box Up And Running 100+ For The Holiday

I hate to talk bad about a product, but over the years I've ran into WAY TOO MANY funny little problems with msd products. I'm talking problems that stump GOOD mechanics.. Mallory or for most cars atleast, the stock stuff supports around 500 hp.

Sounds like a winter project I might just have to look into
