Shower sump pump

[Baysider]

I'm getting to a number of projects and will be opening a few topics, but here's the first.  I'm replacing a very heavy shower sump pump that hasn't worked since I bought my 34. It's likely original to the boat and looks nothing like the Jabsco PARs that are used now. It's screwed on to a chunk of wood which is not attached/glued to anything.  It's in the small compartment with the thru hulls behind the head sink.  My guess is that the wood block was once glued to the hull.  I have a Jabsco PAR, with strainer, and would like to know how the pump is attached in other 34s.  If it's screwed to a board what kind of glue would be used to attach to the hull?  Thanks so much.

Epoxy resin/hardener with microfibers thickener.

Bay : The original OEM shower sump pump was a diaphragm pump not a rotary pump.

You need to epoxy your piece of wood to the hull under the toilet paper compartment. Just make sure that you can get at the filter/strainer on your PAR pump because it will fill with junk that needs to be removed periodically.

a few thoughts

This is the pump I have. It is a bit pricey, but works great and is a lot quieter. It also can handle "debris" very well. I haven't ever had it clog.

Thanks everyone for your input. 

Ron: The pump which is currently installed but inoperable is indeed a diaphragm pump so it's OEM and somewhere in the past 34 years it seized.  I guess they don't last forever.  I'm just hoping my new PAR will last a good long time.  I'll use epoxy to attach a new chunk of wood as you and KW suggest.  What would you suggest to clean the hull surface?

What would you suggest to clean the hull surface?

Acetone.

For a tasty treat: add a dash of 80 grit sandpaper along with Stu's acetone cocktail ;-)

Bay : Don't know if you have or have not checked to make sure that there is power to the old pump - check the obvious first!!

No picture of your hull condition, so "it depends."  I've seen some very cruddy looking hulls. 

If appropriate, before Noah's garni a scrub with detergent/augua solution followed by a rinse down.  Sandpaper and acetone cost 10 times what they ought to and no sense wasting them taking off plain ol' gunk.  Give the wood base the same pre-treatment as the hull (naturally make sure it is competent and not punky.)

A reason to use microfibers is it has very high adhesion property for wood and it is nearly as structural as colloidal silica (which is a pita to mix in.)   

Mix your resin/hardener and pre-brush the hull and wood w/ a light coat to provide a good bond.  Then mix in your microfibers and adhere them together.

Thanks everyone.  I'll be heading north to Champlain tomorrow AM and hope the installation goes well.  I appreciate all of the advice.
