5 of 5 Fast Shipping June 6, 2026
Reviewer: Jeff Schmahl from Grove, OK United States  
I ordered a new Blower for my boat lift as my old one died and left my boat sitting in the lake. These guys had the best price on the internet including shipping and to my surprise it arrived in only 3 days. I had a great experience. (Tip: You can use a shop vac in blow mode to inflate your floats and lift your boat if your lift motor goes up in smoke. Remove old lift blower and your shop vac hose will fit perfectly in the fitting)
