Ive been trying to locate and repair a lower unit leak on my early 80's v6 black max 200hp. First the whole water pump kit including the lower seal-assembly. next the shift shaft bushing and seal kit. at this point i pressure tested it and it held (~12 psi) under water for hours but when i took it out it had water in it again. So I pulled the prop and noticed a milky oil coming from around the prop shaft, so i pulled and replaced both the shaft seals, figuring it could be the shaft rotating causing the seals to fail( which would explain the passing pressure test). Ok so i took it out again for a 10 min test run, about 4500 rpm's in for a good 5 min. and here is the oil....the sample was the Bottom of the oil after i drove back from the boat ramp. and it has settled in this bottle for 2 days. It Does NOT look like the oil that went in, is was gear lube 80w-90 and much more clear. I am asking you all if this has water in it or maybe just the apperance of the oil after it has been 'used'?<br />
