If your cup is glued with 5200 or 4200 check if the glue actually is holding al around. I discovered that small amounts of steering fluid collecting in that compartment on my r27 weakens the bond of the cup adhesive and thus caused leaking of the fluid in the cup
Difference between RVers and Boaters:
RVers move until they reach water, Boaters move until they reach land.
Ranger Tug owners can do both :)

Originally the cup leaked. Two issues found from factory installation, missing o-ring and broken tab or boss on locking ring. After replacing the locking ring and installing an o-ring, filling the cup with propylene glycol. I haven't added a drop. 3 1/2 seasons of use. Put a liberal amount of Vaseline on the o-ring before sliding it on the transducer. This will help seal the transducer and cup and prevent the fluid from leaking.
