I searched the forum and tried everything I could find but I’m hoping I missed something before I cave and take it to a mechanic. So I’m hoping someone has an idea I haven’t tried yet.
Boat ran great all week while scalloping in Steinhatchee. Got home and flushed both motors with no issues.
Pulled the boat today for a quick afternoon on the water. Both engines fired up when I checked them upon prepping.
Both engines fired up at the dock in the marina.
I backed away from the dock fine, but when I moved both throttles into forward, the starboard engine stalled.
I attempted to restart it and it sputtered and then died again.
I let it sit for a few minutes and tried again and could hear it trying to start but no luck.
I brought it home and have done the following.
Pulled the air filter and gave it a boost of starting fluid.
Boat has fresh gas with seafoam in it and port engine runs fine.
Pulled the plugs. 3 of the 4 plugs here black, so I replaced the plugs.
Swapped coils from port engine.
Pulled and reseated safety lanyard.
Checked rear hatch switch.
Pulled and tested all 4 injectors. They were all clean and full of fuel. Clicked when hit with 9v battery.
Ran the engine for a bit with plugs out in case of hydro lock.
Left plugs and injectors out for a good 30 mins in case flooded.
Reseated all parts and checked plugs on coils and injectors.
Engine turns over and will “run” as long as I have the key in start position but shortly after I let off the key, it dies.
Anything else I can try?
