[PSUBS-MAILIST] Minn-Kota Shaft Seals

[Jon Wallace via Personal_Submersibles]

Alec's idea of simply drilling a small hole through the outer seal effectively eliminates it, if I understand the concept correctly.  It also eliminates the need to take the motor apart to remove and replace the seals/bearing.
Folks, do we have a resource that could pressure test a one seal solution as installed from the factory?

 I am not sure why there is an interest in keeping both seals, to my mind the outer seal is dead weight.  Unless you do as Sean says, to compensate the space between seals, the outer seal is useless.  Having two opposite seals is guaranteeing to trap water without Sean's solution.  The proof is in the submersible pumps that operate deeper than our subs.  Just my two cents ;-)Hank
