So, my water pump started to get weak from the pee hole and I got a new kit and changed it out. Also changed the lower unit oil, however, the oil was very milky. after changing out the water pump and new oil in the lower unit, I put the flusher on it and started the engine.
HOWEVER, I had the same issue, water coming out the pee hole was still weak(flow rate of pee hole is something along the lines of a public bathroom water fountain). I turned off the engine after about 10 minutes. So, now i needed to do some eliminations.
Drained lower unit oil and it was little milky, so water must have leaked in there from some seal/gasket. After this I filled up the lower unit with some compressed air (10psi) and sprayed some soapy water around the seals and gaskets, and waited for bubbles. The bubbles lead me to the CULPRIT!! Bubbles never lie. The drive shaft seal was leaking.
I am very puzzled by this because why is the pee hole still weak with new water pump kit. Even if the seal is bad and water is leaking into the gear housing, why would the impeller be effected?? Also, I noticed little bit of groves around the shaft, is this normal? or is this excessive grooving and the shaft is useless??
I am not sure if I did something wrong or what. I dont have a service manual for this engine yet, but will order one soon. I've just been basing everything off of simple logic.
Any advise or help would be highly appreciated, I have lost some sleep over this problem and I am almost at the point in which I promised myself not to do, and that is to take it to the marine shop and let them FIGURE IT OUT and charge me AN ARM AND A LEG.
Attached is picture of the shaft. w/(water impeller housing removed)
