Alright, I have a 1989 Mariner 50hp 3 cyl that has no spark. It has always ran great but stranded me 14 miles deep in the Louisiana Marsh last weekend, which BTW, is not where you want to spend the night. Luckily we were able to get a tow after killing both batteries trolling out to the main channel in hopes to find another boat. But anyhoo, I have whittled this down to the power pack/switch box. I started doing some research an found that my switch box (332-7778A10) is a high performance "racing" part. Most of the switch boxes I have looked at online are the same box but are not to replace the "racing" part. CDI has one but I am pretty sure it will be twice the price of the "standard" box for the same model motor. Anyone have any clue what this "racing" box is all about, will it hurt my performance to replace with the "standard" part. Or for that matter will the "standard" work at all.
