I have finished fitting an electric motor to operate the lift keel on Aztec a Seal 28.

All I have to do now is make a wooden cover to go over the gearbox to match the existing table top.

I believe the same mechanism could be used on a Seal 22.

The operation of the motor and lift is exactly as planned and all my worries about the power of the motor, or the belt and clutch mechanism not taking the load were groundless.

To revert to manual winding all I have to do is slacken the nut on the end of the extended shaft by a 1/4 turn and fit the handle back in its original position at the after end of the shaft.

I feel very pleased to have accomplished this.

Full details of the construction plans and equipment/parts used and where to source them, can be made available to any PSSA member who is interested.

Please see picture below.

Below is a link to a Movie file showing the motor lifting the keel, it should play with Windows Media Player.

The movie shows lifting the keel the last 10 inches or so. You will see the belt drive and clutch discs rotating, then the cable being pulled, and then the top of the keel moving upwards,the clip finishes with the top limit switch cam being operated and the motor stopping.
