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
