[QUOTE="PSG-1, post: 364708, member: 6937"] Spartan Jaw Coupler works well. This is what they use in most Yamaha and Kawasaki jet skis. You will have to drill & thread one half to fit the PTO threads on the back of the engine, and then you'll need to drill & thread the other half to correspond with threads on your driveshaft, which you will probably also have to cut (this is why having your own welding and machining equipment is about the only way you can afford to build a jet boat) This is how I connected my engine and pump. Ran it for several hundred hours like that with the 2 stroke, and with the 4 stroke, I've been running it for the last 250 hours or so, no issues. [/QUOTE]
