I have a 1994 jet boat with a 90 hp mercury sport jet engine. I am about 98% certain the the enrichment system is not working. Boat runs great as long as you start it by spraying so gas into the carbs. It starts back up fine If you shut if off and restart it right away. Choke is working fine.
Just trying to learn about how the enrichment circuit works. From looking at the parts diagram I see it has a solenoid. Where is this mounted on the engine? Is the gas that feeds the solenoid come from after the fuel pump or is it gravity fed? I would image the solenoid feeds gas directly into the intake manifold. Does anyone know of a good website where it can buy a electronic copy of the service manual for a reasonable price?
If the rain holds off tomorrow I will try and figure this out but figured there might be someone on here that can give me a head start.
Thanks for taking the time to read this and thank you for any details on how the enrichment system works on the sport jet
