i have this gen II drive and i originally tore into it to change the input shaft seal, which i did, along with the short yoke, u joints, and upper driveshaft double seal . i pressure tested it several times, used soapy water all over it and cant find a leak yet it wont hold pressure past a couple hours, maybe less, but more than 20 minutes, i have broken it down, and tested the lower unit by blocking the gear lube passage with my thummb and removed the water pump to check the seals beneath, no bubbles there, i spraayed into the prop carrier and shaft seal and found no leaks there either. this is riving my nuts, usually i have some clue as to where to look but i am totally stumped on this one. any thoughts guys?
