I am installing a 54hp Isuzu on a 1.25" shaft. To fit this larger engine
than the small Yanmar
I had in there I will need to get the shaft cut. After the cut, I will have about 2 inches of shaft from the end of the stuffing box cap to the the aft end of the shaft coupler. Is this too little? (the shaft does go through the coupler). For further clarification, there is just about 2 inches of shaft visible between the shaft coupler and the stuffing box.
(The hose from the stuffing box to the stern tube is about 6 inches).
