Installation Tips:

• Do not twist spring section when fitting onto shaft.
• Where the seal plate base has thinned, or worn, use marine silicone sealant on outside rubber-to-sealplate. Do not use sealant on the spring section.
• Never run dry. Running a pump dry will cause the seal to overheat within seconds.
