1994 intruder 150 water in lower unit

1994 evinrude intruder 150 GLERA
Serial #603618278

I was out by boat today after using Sat and Sun and noticed white gear case oil/water seeping from intake screen and from hole on side of lower unit. The hole is located by where my transome saver goes. The whole story is bought boat this spring and had both upper engine bolts snap off. To straightin my now bent shift rod i had to pull the lower unit. The whole lower unit is new as of last year do to a rock bar experience for old owner. Put back together fine an used quite a few times with no problem. First time noticed issue was today. Now dont know if related but the last three times I have had the boat out in slow no wake areas where I have to run slow for a long time the alarm buzzer goes off. My water pressure is 8 psi at like 1000 rpm. So I try to keep rpm up so not to over heat. I back flushed the motor thinking I sucked something up but it seems fine. I talking slow for 8-10 min. Wot water pressure is 28psi. So looking for what i should check first I have service manual and an skilled to tackle any task. Prop seal, water pump related, anything would help since first bigger outboard.

Thanks

There's a seal located just underneath your waterpump assy. where the driveshaft comes out of the lower unit. These are sometimes 2piece and sometimes a 1 piece. The 1 piece is notorious for leaking, especially if no sealant was use when it was installed. Due to where your leak is being seen, I would suspect this to be the problem. While the case is off, air pressure the unit to check for other locations for possible leaks! As always, keep checking your propshaft for fishing line!!
