      A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

        More loops reduce tension. Naturally heavier wire increases tension. – About those old “Simplex” auto rewind starters that used the 43A195 springs – Because the screws holding the fuel tank to the motor and starter housing to the tank allowed some leeway to compensate for variations in castings, The hole in the starter housing for the spindle is large. Whenever the housing is removed for service, it is recommended that tho acorn nut on top be removed and a 3/16″ rod to center the spindle over the crankshaft. Damage happens when the projections on the rope pull catch the Starter pawls as the housing is screwed in place. This happens because the pawls are extended at rest. So when you install the housing, first pull out the starter rope. Release the rope when the housing is resting lightly on the pawls and the turning pully will move off the pawls and drop in place. It must be centered before you tighten the screws.

          Moor loops decreases the tension. On some outboards the pawls could drag at a slow idle. The extra turn decreased the tension so the pawls would extend at a slower speed. Of course heavier wire increases tension. – about those old “Simplex” auto rewind starters. – Because of minor variations in sand castings and the fact that the hole a screw goes into must be slightly larger than the screw, the hole in the starter housing is larger than the shaft of the spindle that holds the rope pull in place. This allows the bully to be centered over the crankshaft with a 3/16″ rod. Most starter damage happens when the housing is tightened with the projections on the rope pull pressing on the pawls. The pawls are always extended at rest. So when replacing a starter housing, first pull out the rope. When the housing is resting lightly on the pawls, allow the rope to retort and the projections will drop into place when they slide off the pawls. Then of course the pulley must be centered before the screws are tightened.
