Hi
I had posted earlier today looking for some help in figuring out what might be going on with my tilt/trim. No luck yet so I thought i would try a different approach.
Here is my story. I have an early 80s 150hp mariner on an Invader boat. The trim up has been sluggish for the last 7 or so times out. This last time it stopped lifting up completely. Once out of the water we had to loosen a line at the motor to depressurize the system so we could tilt it up by hand - heavy old thing! We saw that trimming down pumped oil out of the line but trimming up didn't - Could this mean anything?
Now that it is home I tried pushing the up button again. The motor ran for about 10 seconds and then changed sounds - seems to start to run faster - running empty? Nothing moved. I took the block out that was holding the motor up and it went right down - no resistance.
I want to fill the system up so I can see if anything happens. My problem is likely more than just a lack of fluid but I though it would be a good place to start. 1 to 2 cups ran out when we took the line off - maybe more - it was getting dark. I unscrewed the fill plug and it is full. I ran the motor with the fill plug off and nothing came out but I could still see oil at the top. I couldn't get what I am assuming is the bleed off screw that is just above the fill plug loose - if I did get this loose would this bleed off the air and allow me to fill through the fill hole?
How else could I fill it? - If I take a line off at some point would it suck up fluid?
Also - my new neighbor who happens to be a mechanic (auto) thinks my problem could be a bad check valve - no valves in the lines - anyone know where they are?
Thanks much for your help.
