I bought a 13 ft Boston Whaler with a 2007 Mercury 15 hp 4 stroke long shaft on it.
While it would start right up, when you increase the throttle, the engine dies.
Seller replaced fuel lines and bought a new fuel pump.
So far this has been my experience:
Took delivery at boat ramp, ran at slow speed for 10 minutes (speed zone), then opened it up. It ran fine.
Later same day, took it out. Ran at slow speed fine, when I opened the throttle up, it died, and I couldn't get it to restart. Came home on my electric motor.
Replaced fuel pump. Ran at slow speed fine, ran at WOT fine.
Later same day. Ran at slow speed fine, initally ran at WOT fine, then died, couldn't restart (electric motor home again).
Noticed that fuel bulb would be firm, and then when I tried to start it, if would become squishy.
Anyone have an idea on where I need to start. I'm assuming it is some kind of air leak, but I'm not sure. I've checked the hoses and connections, put hose clamps where there were none, and still have problem.
