I have a 1989 mercury 115 outboard and I pulled my boat out of my driveway with the motor down and now the power trim will only let the motor it go down three quarters of the way .....oops... It seems to me I have forced air into the system and I'm hitting an air pocket when I run the motor down, there is A lot of air bubbles in the fluid. I have been trying to get the air out of the system for several days now with no success .and it is only going down three quarters of the way and stops . I hope I did not do any interior damage to the system such as a seal or a valve .I'm looking for suggestions before I take this system off the boat and take it apart and rebuild it......thanks.
