Well, this is an interesting topic…I was reading a manual describing the orientation of the two lip system on the 6-8hp, and it did not make sense to me. I’m pretty sure that on the single seal cover the seal lip faces up towards the powerhead. And, it would make sense that on the two lip system the seal lips face each other. In other words, the big crankcase seal lip would face down while the driveshaft seal lip faces up…I would think that you would want the small driveshaft seal lip facing up so that the driveshaft would not catch on the lip as you install the gearcase….
But, I don’t think this is what the OMC manual stated…I will have to look at it again when I get home in a few days….
