Hello, I am new to the Forum and looking for some wisdom on my problem. I have a 1987 Baja Force 320 with twin 7.4L 454 Mercruiser engines. Recently the starboard engine cut out at about 45 mph. I did get back to the Marina limping on just the port engine. However I was able to re-start the starboard engine for a while and get the boat docked. This past weekend I changed both water separator filters and replaced the ignition coil on the starboard engine. But, I'm having the same issue with the engine cutting out after 2 or three minutes. Additionally, when the ignition key is turned on the engine does not always turn over - this is intermittent. Previously, I replaced the slave solenoid on both engines when the ignition key was turned but no engine start at all. Again the engine will eventually turn over and start but still cuts out. My next guess is that it could be the TB-IV ignition amplifier module? But would a TB-IV ignition amplifier module fail intermittently and cause the engine to stall out? Or perhaps this is carburetor problem or bad ground or some other wiring issue? [h=1][/h]
