If the problem "Seems" to be in your built in gas tank pickup..Forget IT. Removing the deck to get to it will NOT be worth the trouble or expense. Buy an OMC portable and use that from now on  NB |
Saltwater/Ocean use is relivant if your dealing with electrical problems and corrosion. I have yet to see a boat that has seen salt water and not suffered from it, how well it's cared for determines how quickly it progresses. Corroded connections can cause intermittent and run time problems.
While there is no question Ethanol causes fuel system, and sometimes delivery problems, read the inital description of the problem. Engine runs fine at dock for 10 minutes and 10-15 at 1/2 throttle before crapping out. Based on that description if it really were a problem in the tank, or even the pump diaphram that engine would not run as long or as "good" as described. If you got a bad diaphram it'll run like dog doo warm or cold. If the pickup was bad or even plugged again you'd be starved of fuel well before it ran for 15 minutes at 1/2 throttle. Again just observation based on the description of the problem. Isolating the fuel system certainly works, but I'd go back to get the thing in a failed state and figure out what's lacking and go from there.
