Does any one use a clutch to engage or disengage the prop shaft . If so could you post a photo?

Personally I cant really see the need, but if you must, a simple dog clutch should suffice.

Wes, 87gn, has one on his boat. Let's him warm up the engine without pulling on the dock lines. Maybe he'll see this and post some information. I've never needed one.

If sailing in waters with a lot of weed along the brinks, it will also help keeping the propeller clear. I am also interested!

Wes's boat has a clutch because the controls for the monotube boiler requre the engine to power the fuel, feed and condensate pumps. Thus the need for a sailing clutch. Hopefully he'll chime in with details.

My boat is hybrid (An electric motor is hidden in the seat) I therefore need a clutch. Modes of operation are Steam, Electric and Steam charging batteries.

Is the rope there to keep that beast of an engine from jumping out of the boat?

I was dropping the engine in and lining up. Here's another view of the clutch.

Is the electric propulsion motor also the generator for battery charging? If so:
Does your clutch setup allow ?
1. Steam Propulsion, Motor not turning
2. Motor Propulsion, Steam Engine not turning
3. Steam turning motor, Propeller not turning
4. Steam turning motor, Propeller turning also
I have an inboard electric boat, and am converting to steam/electric, and was thinking of just leaving the motor/generator pulley always connected to the engine shaft. I only plan on using the electric drive while docking, only steam while underway. When the motor/generator is turning without electrical connection it requires very little turning torque, like a flywheel essentially.

Fred,
I'm using an XL X .375 timing belt to turn a small Motor/generator and when it isn't charging there doesn't seem to be any power lost at all. Now if the battery is low and I flip the charge switch, can definitely hear the engine drop down a note. The motor I'm using which is a 60 volt DC servo motor, had bronze bushings in it and I pulled it apart and re-machined the endplates and put sealed ball bearings in it. Turns very smooth with little resistance.
Preaton, the clutch looks like it will do that job. Beautiful York Compound too!
