Today I ended up in some shallow water in my skiff and when I got out, the amount of water being pumped through the motor was restricted. I still have some water flow, but I'd say it is about 25% of normal. It did not get too hot, so I don't feel I did any damage to the motor, however, I don't see any obvious issues outside the motor, so I suspect something has partially obstricted the cooling water inside or at the impeller.
Where should I start looking? Any common areas where these motor may get clogged up?
