I have a 1979 Mercruiser 228. After running all day today I came back to wash down. The trim went all the way up, but now won't go down. The "automatic stop" has not worked on the trim for years, and the indicator hardly works as well. When I hit the trim up buttons, I can hear the motor run, but nothing when I try to trim down. Please let me know where I should start to investigate.
Thanks in advance.
