Hi,
I just replaced the trim n tilt pump motor on my 93 Evinrude 90HP.
The motor was about 100% up last year when the pump failed.
I manually lowered to about 80% when trouble shooting it before I figured out it had a dead pump and it remained in that position all Winter.
There is no question that the problem was a dead pump because it's housing was rusted through and wouldn't spin with 12 volts applied directly to the leads.
I was hoping that after installing the new motor it would just start working again but although the motor runs nothing happens at all, no motion what-so-ever and it doesn't sound like the pump is "working on any fluid".
When I removed the old pump motor I had a little fluid leak out but not tons.
I removed the large cap on the resevour tank and fluid started pouring out so I quickly screwed it back on and assumed that there's enough.
I'm thinking the pump unit might be air-locked?
I still have the motor suspended over the transom as I had to pull it to get at the most in-accessible pump bolt.
So now what?
I'm sure I'm 90% there and I'd really rather not enter the waiting line of my local OB shop.
Any advice from knowledgable mechanics would be highly valued.
