With the development of cartridge ballast pumps, changing out a damaged, non-working pump has become easy. The Attwood Tsunami pumps feature this quick change option and allow users to get back on the water in minutes rather than hours. Keep a one as a spare and get back to enjoying life on the water before anyone notices there was an issue.

This is the new updated version of this replacement cartridge, which is the Attwood 800GPH MK2. It offers better priming and increased durability, and is 100% backwards compatible with the original pump housings making it the correct solution for any Attwood Tsunami 800GPH Cartridge aerator pump.
