I am not wanting to sell mast as I hope to fit a hinge( it's 10 pc higher than partners of total height) I'm thinking tabernacle is at the partner a hinging table? And I made an electric outboard using seagull dogleg. With an impact driver(140nm) is good for inland water way I've been told this will destroy gear cogs does 

any one have an opinion on this is a flywheel required or an attenuating rubber coupling? Torqueedo is more than I can afford and seems less than robust

Don't have dimensions available it is the rig off a production kingfisher22 JR ; a blondie hassler junk rig, it is all complete with battens, blocks and running rigging. Not keen to split them up as its a complete system designed by the pioneer who popularised the system in the west. rob
