Engine hatch cover would not open - sliding collar too tight (problem solved)
I'm just documenting a problem with my engine hatch cover, and how I solved it. Maybe it will help others.
Boat: 2007 Rinker 370
Problem: Engine hatch stopped working. When I pressed the button on the helm to open the hatch, I could hear a faint click near the battery switches, but the hatch would not move. The breaker was not popped, and the batteries were fully charged.
Solution: Readjusted the sliding collar at the top end of the engine hatch actuator.
Explanation: At the top of the actuator, there is a sleeve 4" long with a slot on one side and a nut/bolt at the top. The sleeve is meant to slide up and down to allow some play when you close the hatch. On mine, the bolt was overtightened so the slide could not move. When I closed the hatch cover, I was too slow releasing the button, and the actuator started pulling down on the hatch cover. The tension caused the actuator to bind.
To open the hatch: in the center of the hatch cover, I removed the table base (6 screws) and used a razor knife to cut a slit in the insulation. I was able to stick my arm into the hole (all the way to my shoulder), reach astern to the top of the actuator, and remove the pin that holds it to the hatch cover. It was not easy with the actuator under tension, but I got it out. Then I had a few friends with strong backs help me pull the hatch cover open so I could get into the engine room and prop it open using the leg on the underside of the hatch cover.
With the tension removed from the actuator, it went back to working normally. I adjusted the bolt on the sliding collar and reinstalled the pin - problem solved.
