Hello all...I have a 1979 evinrude 100hp with tilt and trim. 1 of the pistons was leaking so i replaced the seals put back in, and re filled with tilt and trim fluid. After about 3 weeks this am there was a good amount of oil on the ground. I think majority was from the screw area but when i put the motor to the full down position, the left piston (one i didnt touch) sucks all the way in and the right one is flush to the motor...Why would they not be lining up?
