suzuki 90 trim probs

[EdGriffiths]

Just bought a 2nd hand rib with a 2002 suzuki 90hp 4 stroke, engine runs perfect, printout shows 70hrs, full service history etc.
£rd trip out, the`s some noise when trimming up. Inspection after use showed small leak of pink (aerated?)fluid from behind piston. Leak has got worse, and on trimming up, the top seal in the piston can be seen to fail. Will new seals cure this, or is it a new trim unit? help/advice please!!

Assuming there's no pitting on the ram then new seals should do it.
