Re: 1980 mercury 70 no tattle tale
Well,
We attempted to start the motor yesterday, and got it running for short periods of time (8-10 second bursts). I'll deal with those issues later. We still didnt have any water coming out of the pee hole, so we stopped attempting to run the motor and decided to chase this down. So we pulled the cylinder head cover (not really a head). It was a little dirty inside, but not bad. So, I pulled the exhaust cover (both pieces), again a little dirty, but not bad. So we lifted the powerhead and removed the base plate, and found that water had been lifted into the base plate, and the base plate was wet above the copper tube, but the base plate had not even filled with water and pushed the water uphill. So, either the water pump is not working, or we didnt have it running long enough, or the new impeller isnt working properly. When I had worked on the lower unit before, I replaced the impeller and inspected the water pump casing and it looked good, but I'm gonna pull it again (need to anyway to mount the powerhead) and check everything out there.
