The pump will be a the back of the boat behind/under the rear seat or engine
depending on the layout of the boat.
It will not be in the ski locker as that is not at the rear of the boat.

They are fairly cheap and usually a lot easier to replace than repair.

My family has an 18(?)-year old Shamir Sidewinder ski boat. For several
years now, the bilge pump has not worked. I can hear it humming when I
turn it on, but it does not pump any water. Any suggestions that do not
involve much dismantling of the hull?
