I went through page after page of the forums after searching and didn't find my particular issue, so here it is-
2000 Chris Craft Volvo Penta 5.7
Down to the lake for the weekend, temp 90+, water temp 78 and a bit lower. Boat ran great for 45 minutes, with starting and stopping included. Then after sitting for about an hour it started right up, but when we'd slowly cruised out of the cove and gave it throttle, it died. And would not restart. It cranked fine, but seemed to be starved for fuel. Pulled it back to camp, got tools, and took the carb cover off. Dribbled a little gas into the carb and it ran long enough to use the carb gas, then died again. So I figure fuel delivery problem. Pulled hose from bottom of separator/fuel pump and it was full. Pulled hose from carb and it was empty. Tried cranking it and no fuel out of hose. Pulled the separator and it was about full, dumped it and filled with new fuel. Tried cranking again- no go. Pulled the fuel line from carb again and back-filled it to the pump. Engine started right up and ran great while we played. Went back to camp and and ran around again later and it ran great. Next morning it wouldn't start until we back-filled the line again. Ran perfect again until after we shut it down again. It sat for 3 hours then wouldn't start again. Even after back-filling it wouldn't go. Let it sit for a couple more hours (I was afraid I'd start throwing things around if I kept at it). It started after filling line again. After this it ran fine the rest of the time.
I called the resort mechanic and he suggested vapor lock or bad fuel pump. I would think the fuel pump would show up first when really pouring on throttle, not intermittently. Vapor lock should clear up after a whole night, shouldn't it? Son now says it did this to him last summer, but not as bad and only once.
Where do I start?
Thanks
