The Horesepower categories above represent the maximum horesepower required to obtain the full performance from the pump. It does not mean that that pump will only fit the engine with that horsepower output. As long as your engine if 7/8", has the same bolt battern and accepts straight shaft pumps, any of the pumps should work. We state SHOULD because some small consumer power washers are made so that only a direct replacement from your power washer manufacturer will work. In the event that you order a pump that does not fit a 15% restock fee will apply as long as you do not damage the pump. If you have any questions call us Toll Free at 1-877-824-7763.
