Hi,

I have a 2008 Optimax ProXS on a 20' bass boat, which starts and runs fine but performs worse that normal. In trying to diagnose what is wrong I determined that it isn't firing on cylinder 4. I switched wires with another cylinder to make sure it isn't that. Does it seem like it is the coil? It looks like it is very easy to change. I realize to be complete I could have switched coils with another cylinder but ran out of time.

Thank you.
