G'day all I am new to the forum and appreciate any help that can be put forward.
My DF140 sat for 6 months while I was doing some fibreglass work on my boat. I gave it a service, full impeller kit, lower unit oil, engine oil, plugs, filter, internal anodes, thermostat. After the service I ran it on muffs and could hear a rattley sort of rumbling gear/ bearing noise in what I believed to be the lower unit.
I pulled the lower unit back off and when turning the lower unit by hand it felt a bit notch if you applied downward pressure. I spoke with the local shop and ended up taking the lower unit to them.
It took 2 and a half months to get it back and a surprisingly high bill. They replaced the driveshaft and fwd gear bearings, reshimmed it, new oil seals ect. Got a bill for nearly $900 AUS.
Anyway, I finally got enough other jobs on the boat finished to put the lower unit back on the engine and run it with muffs on. The noise is still there !
I read though other peoples posts on similar noises and the either come to a dead end and get no response or never report back on the issue or, the finger gets pointed towards the mid section bush.
So I pulled the mid section and removed the bush to inspect it. Bush is in good condition and there is no corrosion where it mounts. I have added some grease and will reinstall it all, but I don't believe that was the issue.
I ran the engine for a brief period with the mid and lower section, can't hear the noise anymore.
Really the lower unit should be good to go after having the shop do all the work they did, but I am sceptical.
Does anyone have any ideas of experieexperienced the same issue?
Cheers,
