Can you remove part of the rear deck on Triton TR -18 -19- 20? So you can get to the Livewell pumps. There is a plastic cover around the back toe rail I think there are screws or bolts under trim holding it on.
The only way to get to them is take nearly everything out of the battery compartment, take the bilge cover out, hang upside down with your head under the rear seat post, and cuss like a sailor swearing you will never buy other Triton in your life.
Or at least that's how I did it...
