OMC 1.8l V4 seadrive quit

[ARERHODES]

Yesterday, after running at high rpm for approx 30 min, motor stuttered then lost power. Picked up power for another few min, then sputtered out. After engine was off, bulb needed priming. Motor would not turn over after several attempts. Finally, after the 8-9 attempt, motor turned over after priming bulb, and pumping throttle in neutral. Ran for another 10 min or so as I limped back to the ramp. Motor died out again at low RPM, would not start, would turn over but not start.

Carbs have not been cleaned yet this year. Boat is a 1987 V20 with a 87 1.8L OMC Seadrive. New plugs installed this year, only have an hour or two since the problems. My guess is a fuel delivery problem/obstruction. This happened yesterday evening and have not had time to start investigating.

Any ideas on where to start?
