Hello, after some frustrating low power situations, and my boat stalling from time to time I believe I have found the solution. I changed the distributer cap and rotor. I felt I should share this as I didn’t really see a post that stated just how easy this is and how quickly it fixed my issue. It’s so easy to check / change that if you are having issues I would check it straight away. I had some corrosion on the cap. And the rotor seemed to be worn out. Happy boating.

Hey guys, I've got a higher hour sportster I bought last year. Planning to have the carb rebuilt and do a few other things including the distributor cap and wires. Does anyone know if there is an msd distributor for this application or can you recommend another option? Also what aftermarket plug wires are there available?

What's up crew!!! Need some advice from some of you gear heads. Found a cracked block after winter storms. Every mechanic I talked too was 6 weeks out, so I decided to just buy a new long block and install it my self. It was time consuming but not a terrible job. New motor is back together and in the boat. First start was a little stiff but eventually fired and seemed to idle normal. I then scheduled to take to local Malibu dealership here in Houston for them to set the timing for me. Here is where I need your help. They claim that the timing will not adjust. So I am not sure where the problem could be. I have removed timing cover and checked that timing chain is correct. Distributor points at #1 at top dead center. Could the ecm be in some sort of limp mode that is not allowing timing to adjust? Is the distributor off a gear? Started again on hose yesterday, and I see what they are talking about, when you turn distributor there is no change in engine. If you turn either way very far it just dies. Any help would be great
