I finally put some time on my 6-71 blower and i'm having some issues with the gear case on it. Just cruising around i'm getting tremendous pressure in the case its pushing oil out of the snout bolt holes and even through the pores in the aluminum on the snout. Any ideas on what could cause this problem? I'm using 80-90wt gear oil and filled it to the snout hole that is in the aprox 7 o'clock position. It doesn't have a fill sight glass or bolt and no pressure relief. Also this blower cam with the boat and the guy before me never ran it, so how would i tell if it was setup for alchool. cause the cases get hot to the touch while running it. It has strips on the tips of the lobes. In the photo you can see it pushed out the tread sealnt on the snout bolts. along with some gear oil.
