Manual Bilge Pump - Plastimo or Whale

[Quickstep192]

My boat has a Whale manual bilge pump like this:

Marine : Whale Pumps 12V Henderson Plumbing Bilge Diaphragm Submersible Pressure Water Systems Marine Caravan RV Shower Drain Portable Sanitation Purging Groundwater Solutions Voltage Electric

The diaphragm has blown. I either need to re-build the Whale pump, or replace it with another pump.

I'm considering the Plastimo Cockpit Pump like this:

Plastimo - Catalog on Line - Pump 925 and 1038: with telescopic handle;Pump model:PUMP 1038 sans By-Pass;Output:1 litre per cycle;Capacity, as per ISO 15083 standard (45 strokes per minute, with a 10 kPA depression):45 litres/minute;Weight (kg):0,920

It has a nice clean look, but I don't know anything about the quality.

Can anyone offer any opinions or experiences on Whale vs Plastimo?

Both are decent quality pumps and known brands. I would rebuild the Whale. Done that with several I have owned over the years.

I take it your boat is not large by the pump details. Both products are reputable and manufacturers have been around forever. Re & re on the Whale should be routine with the rebuild kit. Plastimo avoids the rebuild but Murphy guarantees it will not be a direct swap - bolt pattern, inlet/outlet angles, etc. Potential weakness with Plastimo is that extendable handle. It's cute and streamlined, but will it hold up when you absolutely need it? Last year we had one of the West Marine extendable winch handles. The handle snapped cinching the main on our second race, and slid 80' to it's watery grave. Learn more about your boat system, have some fun, do the rebuilt.
