    LM 318 running rough over 2500 rpm

    Hello, I have an 81 Silverton 31c with 318's. It just went back in the water, and on the first real cruise, the starboard motor is having trouble keeping up with the port motor.

    LM 318 noise / leak from intake manifold

    Multiple questions on 318 refresh

    Hello, I recently posted a question regarding one of my motors not being able to stay running. Thanks to all who responded. The suggestions led me to the issue. I'm refitting a 1981 Silverton 31c with 318s and V drives. Both of the motors have now started and run long enough to reach operating...

    318 wont stay running

    Hello, I have a 1981 silverton 31c with twin 318's. I'm refitting the entire boat, and I'm trying to get the motors running again(they haven't run since 2009) The Starbord motor starts and runs fine, but when I just tried to start the port motor, it fires, but when I let go of the ignition key...
