Engine is a much modified version of a pre war design. Scratch built by the builder, who if I remember correctly, made all the castings, patterns etc. Even made the miniature spark plug. Test run only by the builder. I never got to run it myself before selling the boat. Now safely stored away.
The updated Sea Queen still available from various suppliers including https://www.cornwallmodelboats.co.uk/acatalog/sea_queen.html
I restored one of the originals from a wreck a few years ago. No propshaft or rudder had ever been fitted, the propulsion and steering was via a small electric outboard motor on the transom. Don't want to hog this thread but a couple of photo's before fittings added and a trial fit of a home built ( not by me )15cc 2 stroke engine. Had my arm twisted to sell the boat but kept the engine.
Hi Brian.
The Monkey Winch booklet was passed on to Chris Sutton ( The Showman ) who might still have it, but it could now be with Iain ( slf-uk ). A PM to both might help you. The winch was sold a few years ago. Can't remember how the pawls operated now.
Good video again Joseph and another tractor brought back to life. I think the angle iron bumper ? was probably fitted before John acquired the tractor.
