    26 fluid ounces for a 20" shaft. Next time read the ownders manual before you ask a question.

    Changing lube each year has been burned in my brain for so many years I cound not resist. I must say the lube looked (actually smelled and no I didn't taste it) the best I have ever seen after a year of running. Plus the fact I was killing a day while the tree guys were cutting down two trees that got topped by Ernesto. Normally I would cut the trees myself but a day in 30 to 40 MPH gust about two weeks ago while fishing caused a few bruiesd bones to put in mildly. SoI left the tree climbing and cutting to the young guys.

    Remember that E-tec uses HPF-XR lube, not the HPF-Pro. It is made for extended run time, that's why it looks and smells soo good. We are starting to use only the XR in the shop now, it's easier than having two or three gearlubes around, "why not just use the best and forget it ", I always say. I know, old habits are hard to break!! I change mine every three months when I'm actually fishing.

    Great info. The lube I used was PN775601 Ultra HPF. Is that the good stuff? If not whats the PN on the XR lube?

    Thanks
