Greets everyone, I'm new here and could sure use some advice.
I just acquired a used 1983 Mariner/ Yamaha model 5C (5 hp) outboard. I replaced the water pump assembly (complete) with all new parts. I then proceeded to crank her up in a trashcan full of water, and I noticed I was only getting a slight spray of water and not a full blown stream out of the pee hole (located on the rear housing just under the powerhead). The water was tepid, but not hot (about 70-80 degrees).
I ran the motor for about 15 minutes, and the powerhead ran warm, I guess around 90-95 degrees. Never attempted to shut off like it was overheating or anything. Cranked right back up.
Is this normal for this motor, or should I see more water coming out the pee hole? I'm just getting a drizzle/ fine spray.
Also, what should I look for or attempt to do if it's not normal?
I know I did the water pump correctly...I've done a few before on other motors. Also, the foot was submerged well below the level of the water pump, so I know that part was OK.
Does this motor typically pee hard, or just drizzle???
Thanks for your help or advice.
