Call if questions
My name is Aaron and I work at Sawyer and take care of potential warranty and/or repair issues. The suggestion from cnile970 should resolve the issue, really a great suggestion. If you remove the blade and look up the shaft there should be a foam plug there just beyond the 3/4" titeset hole, that is there to keep the water out, but sounds like this plug may not be there possibly.
If you are having any trouble or need any assistance, please give me a call at 541-535-3606 (Sawyer Paddles & Oars).
