I have an issue where my motor will not stay up when trimmed up or down when trying to drive. I can put it up and it stays up about 30seconds or so and then slowly goes down. Not enough that you can really see it by eye but it can be totally down in a few minutes. I did find that I had oil leaking out when I got the boat a few months ago. I also found the previous owner had stripped one of the holes when replacing a line and it is now fixed and no longer leaks. I read on here that I needed to remove the air in the lines by raising and lowering the motor at least six times. I have done that over 25 times and actually still went out with the boat and it still sinks or comes up when I am trying to drive. I know the motor is an 83 but I can not find any info on the trim and such and steps to go thru to fix this. Please help. I have attached a few pictures to try and help. Any help is appreciated.
