It's serial 0G590511. A new lower unit was purchased and installed in early 2014.
Used during the 2014, 2015 and 2016 seasons (gear oil was changed each year).
Drained the gear oil a few weeks ago and put it in a glass jar. There is some dark tan
fluid that has settled to the bottom. A pressure/vacuum test shows that there
is a very slow leak. I've read on this forum that a vacuum test is the most important.
My pressure/vacuum tester has a meter on it....how much vacuum should I apply?
How long should it hold for? Is even the smallest leak worth following up on?
My Factory Service Manual says nothing about pressure/vacuum testing!
