1998 johnson fast strike LU help please

[turkeycreektrout]

hello all, need advice

motor is a 98 faststrike 115 v4

i changed the LU oil last summer. it was a little milky. took it to dealer and they did pressure and vacuum test and everything turned out fine. in the fall i changed it again, little milky. changed it two weeks ago and it was coffee with cream milky. no actual water drained, just the milky oil.

i guess my question is, what could be happening if the tests check out? should i just change it once a month and not worry about it? i have heard shift shaft seal or upper drive shaft seal coul be bad. does this mean water is getting in where the LU attaches to midsection? i have thought about buying a manual and learning, but i just dont know what to think, and tourney season is fast approaching. any advice would be greatful
thanks in advance

If you are using the cheap automotive 80/90w gear oil ,some of them areate really bad and look milky. Save a sample in a clear jar and let set to see if any seperation occurs, the water will go to the bottom. If it just clears up switch to a better oil(Luberplate or OEM).
