Old Graupner boat with OS .21 SE-M engine. Questions...
I got this boat from a friend, and I'm gonna try to get it running. The engine is locked up solid from old dried castor oil. I have yet to remove the engine and clean it up yet. My main questions are; is this engine (circa 1985) worth a damn? Any idea what a good length for a tuned pipe would be? It was also suggested to replace the drive unit/rudder assembly with a standalone rudder and run the prop directly off the drive cable. One of the yokes on the prop shaft is broken, so I need to obtain parts anyway.. Might as well do it right the first time. The hull is in decent shape - some small cracks above the waterline that's easy to repair. The inside of the hull/engine compartment is pretty castored up, but the wood is in good shape. I'm gonna try to refurb it some and get it running if it's worth doing so. Pics attached. Any help or ideas welcomed.
