Hey John. I have the same exact boat with the same problem. I've talked to a few owners and I think I narrowed it down to the vapor separator. I also have the ticking sound from the primer pump on the side of the engine. Ticking also coming from the square plug next to it. Relay switch I think it's called. I have changed both new. I changed the water fuel separator. It was pretty rusted on the inside. I pulled the drain plug at the bottom of the vapor separator and got no fuel to come out. I figured this was it. I pulled the vapor separator out today and found the inside filter clogged very bad with what appeared to be thick grease. Just years of build up I guess. (poor maintenance ). There is a fuel pump inside thus unit as well. I hooked power to it from the battery and it kicked on so thankfully it's good. So after cleaning this unit up I'm going to put it back together and hope it cranks. The inner filter was so clogged that there was no way fuel was getting through it. I could actually leave the key on for a while and let that ticking pump push enough fuel through the system that the boat would actually fire for a second then cut off. It's not an easy removal and I'm sure putting it back together is going be more time consuming. Wish me luck
