Mercury 150 4 stroke, 2B059417 Aug2013
Hi, I have dual 150hp Mercury 4 strokes 3.oL setup on a plate aluminium 27ft boat.
Port engine will not start as I have no spark. I turn ignition on but fuel pump does not do the initial pressurising for start up. Disconnecting plug and putting power directly to fuel pump it works perfect. Starboard engines runs and idles great but under load it struggles at 2500 to 3000rpms. Also at that rpm it displays on the smartcraft gauge "critical oil pump" What can I do to fix this? Cheers Cameron
