The ignition switch has likely had moisture in it and corroded the contacts for the engine kill circuit. I picked the epoxy off the back side of the switch to expose the screw heads, then disassembled and cleaned and greased the contacts. Works like a charm now. (Note I had to do similar service for the switches on the rear hatch as they were intermittent)

Mercury outboard no spark
Check your engine kill switch disconnect the wire from one side and see if it sparks if not then it is probably a bad coil or exciter coil. They do go . Make sure the engine is in neutral .. Test this by twirling the prop in both directions. It will free spin in your in neutral the boat motor will not spark if it is in gear.

Looking to repower 1997 Four Winns bowrider with newer outboard engine. What max HP is boat rated for? Found Yamaha 150 XB 2016 for a good price . Will boat work with a 25 inch shaft? Thanks,Kathy
there should be a manufacturers plate attached to the hull of the boat with a number of passengers it can carry and the max hp motor allowed to be fitted
talk with boat shops as they will know the approximate hp for each make of boat and length
while it may be attractive to fit big hp motors to small boats , it in fact makes the boat less sea worthy and makes capsizing easier so get the advice right from the boat shops

Yamaha Exciter jetboat: eng stops when warm, not overheating
I have a 1998 Yamaha Exciter jet boat as well and am having a similiar problem. I just took it in today and the mechanic believes that it may be the oil pump failing which causes the pistons to stick and not lube the engine properly, thus causing overheating and eventuallly stall. The one motor sounds beautiful and the other sounds unhealthy. He checked compression and it seemed fine and it has new plugs. Maybe this is the same problem you are having...Hope this helps...

Have some turn the engine over and ground each spark plugwire to see if they spark. Good plugs won't matter without juice.
