1988 sea ray sorrento with 5.7 mercrusier and alpha one outdrive. Boat was running fine then sat for a week. had difficulty starting which is now corrected. runs smooth out of gear and accelerated properly. timing correct tuned up with new cap rotor wires. When placed in gear will not get above 2200 rpm and no power. if continue to run will eventully plane out slowly yet top speed 28 mph and no real power. Looking into carb have good continuous flow of gas. Seems to be fuel or ignition problem but i would expect it would also be a problem out of gear. no noise from outdrive or from enigne. ie valve ping or knocks. Does anyone have any ideas and could this be ignition module. One other note fuel gauge stopped working at same time. oil pressure stable. temp stable. oil not leaking and clean. this was a sudden change working fine then not.
