15 customers mention13 positive2 negative

Customers like the water movement of the pump. They say it moves a lot of water, is quiet, and delivers plenty of water. Some mention that it recirculates water in their bait tank and empty standing water from the hull very quickly. The pump stays submerged in ice water and runs for 20 to 40 minutes at time, and it drains the bilge quickly.

4 Stars
Good products.
Used them for years. Always been good, 5-7 years service life as aerator pumps.The only reason for the 4 stars is the way they arrived. Looks like a dog got hold of them. No damage to the pumps though.

Reviewed in the United States on September 9, 2023

The unit is quiet and moves water well, but the most endearing feature for me; a quick click and twist to remove the motor from the base. This may not seem like a big deal, but in my boat, the bilge area is VERY tight to get into, and I needed to replace the bilge pump. As this T500 unit was in my new boat, I could simply twist the motor out and replace it into the pre-mounted base (connect wires as well). If I had to fully/traditionally replace that unit, I would had to removed gas lines, gas vent hoses and maybe a piece of the floor: it was a huge time saver. BTW, the replacement motor on Amazon is 10 dollars more than buying the entire kit....the motor is the same, save the money

Reviewed in the United States on July 25, 2023

The Attwood V450 I installed in my boat 28 years ago finally snapped a retainer that held it in place to its mount, and after digging through the multitude of options I bought this Attwood 4606-7. Installed easily with 3 #8 SS pan head wood screws and as best as I could test it works well.

Did need to upgrade the fuse from 2A to 3A as this pump draws more power than the old one, something to be aware of.

Cheers!

I adapted this bilge pump to replace the live well pump on my pontoon fishing boat.
Limited space on the existing bracket made for tricky positioning and fastening. The result was excellent!
