    OK, well first be sure it is actually gear oil that is leaking/weaping out of there….Might be crankcase drool….
    Have you pressure tested the gearcase? I know the stevens tester is expensive, but they do sell the screw in adapter for the hose separately at a reasonable price…Then, you could make up you own pressure tester easily….Just don’t over pressurize and blow out perfectly good seals and orings, just takes about 5PSI, then immerse the gearcase in a bucket of water to pinpoint the problem aread….
