I am fortunate enought to be able to fish most of the winter so I store my motor down with no transom saver so that the water can drain out. I started noticing a small leak around the port side trim cylinder that was very minimal. Had my spring maint. done recently and the mechanic replaced the o-ring on cap and tightened up with a spanner wrench and said that should fix it.

Now it is very slowly leaking and appears to come from around the piston. I wiped it down good and it didnt leak for 4 days then all of a sudden today there was a small bit of trim fluid. Seems to leak at odd and inconsistent times. I have heard that once they start leaking the whole thing needs to be replaced. Could this be from storing in the down position this winter?? Should I take to dealer to see about getting it replaced? Thanks for your time!
