Yup, That's about Par....
My '88 came with two of these pumps. One was designated for the bilge and the other, even though also having the pickup mounted in the bilge, was designated for the shower. Each has a switch panel with ruby light and a float switch.
The two pumps were worth about (retail) $500. total when new. One of ours had a busted diaphram and after finding that that model had been superceded by a newer one, i replaced it with a PAR 37202 series 2.

Here is a listing from one of many vendors that sell this. Note that they reference the model our boat came with: "New and updated version of the famous 37202 - the best selling small bilge and shower sump pump in the world."
I was rather pleased to see that Ericson had put these in -- plus a honkin' big manual pump with the handle mounted beside the helm position. This is something you *never* see on cheap boats.
I have heard of motors failing on the original models after many years, and would note that pumps/parts often show up at swap meets and on eBay. Whether it is better to rebuild or replace after a couple decades is a personal decision. I figured that it is my time or my money either way, and one tends to equal the other at some point...
Of course in any given month, I may have more of one to spare that the other!
