I am looking to see if changing spark plugs will help with a slight miss I am having.. Purchased the boat a year ago.. changed spark plugs, and ran great for 2-3 uses... now its back.. I would like to know if anyone can suggest the best spark plug, and what is the OEM plug.? Not sure if the ones that were in the motor were OEM or not..
I am going to check the fuel/water separator as well, although it was changed just a couple weeks prior to the issue..
Any TIPS? have run plenty injector/carb cleaner through it hoping it would help... not much if any change..

THANKS!!
