I have a Super 5 steering adaptor that was made by Allan Brown of BTM, former manufacturer of all Raceboat accessories. It is new & attaches to the bottom two water jacket bolts & allows attachment of the BTM folding steering bar for Mercury Quicksilver motors. Never used. I will sell for 25% of what it cost me. $100 includes shipping.
I also have the wire form remote throttle hook up that slips on over the throttle shaft on top of the carb. It then allows attaching the inner Bowden wire from the remote throttle to the connector & the outer Bowden wire to the tiller handle. I have a solution for that as well.
