We have a 96 yachttwin 9.9 two strokewith electric start. Tried to start it today and it spun up then justlocked up. I thought I had a hydro lock so I took the plugs out. Notthat. Solenoid would not engage. I wacked it and it fired right up. Iwanted to make sure I could start the motor out on the water so Itried the pull starter. It's locked up tight. Won't budge. Motor willnow start with the starter. but not the pull cord. What's up? Any thoughts?
