All -
Took my 1997 malibu echelon for the first time this year yesterday. Engine is a 320 efi monsoon.
Engine initially starts fine, runs fine and pulls a skier.
We sit for about 1/2 an hour and boat starts and dies. Will idle for a bit, but chugs and dies under load. Backfires at least once. Also smell fuel. I had it towed down the lake as it wouldn't run for any period of time.
After getting on the trailer, I pull the distributor cap (replaced about 3 years ago) and it's corroded. The whole area under the distributor cap appears to have received moisture at some point. Clean it and rotor button (quick clean) and same issue. It appears there are some electronics (ignition control module?) under the distributor cap which are corroded as well.
I'm going to change out plugs, wires, rotor and cap. Given how bad the piece of electronics looked, I'm considering changing it as well
Couple questions - Is that the electronic piece (suspect it to be ignition control) marine specific part or can I pick up at an auto parts store? Any other ideas on what it could be? As stated above, boat was fine until it sat after running.
