Weak spark on starboard engine

[shipwrecked]

I have a 2002 2900 with twin 4.3 engines. Boat was running fine but last time I tried to use it , the starboard engine would try to start but wouldn’t quite get there. I checked the ignition module by swapping it out with a. Known good one, but still has weak spark, would this be the coil?

It could be either a bad coil or ignition sensor that is in the distributor. Try swapping the coil since that’s easy.

Ok but why not swap them before spending the money?
