H2O Designs has both a 148 and a 155 pump now. I run a H2O pump for several reasons, it really was not a hard choice once you factor in quality. H2O pump does not have any welds, solid stainless and they have a consistent build quality from piece to piece. You’ll never have to worry about it swelling or about running a different pitch prop due to vanes being welded wonky. On top of all that its Made in Merica' by guys that ride and give back and support our freerides here in the USA.
