Good Morning All... We are rebuilding/refurbishng an 1977
Marine Trader 44. The motors are Ford-Lehman 120 hp six cylinder rusty brutes. Lots of unknown
engine hours. During the
delivery south, the stbd unit began making loud banging noises. There were no indications of problems from the fly bridge - No alarms, normal gauges, no vibration etc. The unit ran at normal
RPM until I trottled back to investigate the
noise. A I took it out of
gear, the
motor ground to a halt.
I can move the crank through about 1/2 revolution with a breaker bar and socket. The starter will not crank the
motor. There is still full
coolant in the expansion tank, and full unburnt
oil in the sump.
Local mechanics have told me that it is quite possible that the damper plate located at the tranny/motor interface
lost its springs and jammed up the motor. I have not heard of this before.
Anyone out there with similar experience? Suggestions? I would rather hope for a simple solution rather than a total
rebuild.
