1989 32' Carver with the original merc 350ci engines. have had the boat for 4 years. engines start/run/idle smoothly and powerfully. when first started and warmed up, the engines will run 3000 to 3200rpms (about 14/15 gph) for an hour with no problems. one motor will suddenly stumble, like it's not getting fuel. it will pick up again, and stumble, worse and worse... backing off the throttle all the way and shutting off the engine for 1 minute, then restarting - it will run perfect again for 20 minutes? it happens to both motors randomly - with two completely independent systems. (different fuel tanks/lines/pumps/filters...) have changed the filters (both in-line and fuel water separators) numerous times, and see no visable particles, nor any significant change. pulled the pick up line out of the tank and inspected... nothing notable. ideas?
