Hello. I have a ZF250MA, installed new 4yrs ago, now has 1700hrs. Shifts & drives well, has own
oil cooler, runs just barely warm to touch. When I’ve changed it’s
oil, always clear and had no burnt smell. My concern is that I’ve done 1/2 a
circumnavigation, with my feathering prop frequently not feathered(different story)......so let’s say 10,000nm of rotating undriven.
I’m going to haul soon, and pull the
motor for
maintenance.....and I’m wondering how to judge the condition of the
gearbox without sending it away.
Any simple, proven techniques from someone that knows transmissions?
