Snake River wrote:Susitna907 I will try and address the questions that you have asked. First of all the pump/engine assembly that we are supplying with the Rotax package is the same one that the fiberglass boat industry has used for many years now with great success, and is not the same pump assembly that comes in the units that are scavenged from personal water craft. Several fiberglass manufactures used Sport Jets in their boats but have since replaced them with these engine and pump assemblies.The pumps that have been used by the fiberglass industry have been very dependable, and have worked quite well in waterways that are full of silt and trash. As far as ingestion of heavier debris we have redesigned the intake and intake grate to have 15 bars with 3/8" spacing to help keep any large debris from reaching the inside of the pump. The pump comes with a new BRP designed heavy duty stainless steel impeller and a wear ring that are specifically designed to meet the demands of our OEM customers, not the same light weight impeller used in watercraft applications. We have developed a 1" billet intake block, cast aluminum suction housing, and steel stomp grate all of which will come as part of the package that we will supply to the OEMs. Please keep in mind that everyone working for us and involved in this project have come from the welded aluminum jet boat industry, and we have kept the tough demands of our industry in mind in all of our developmental work. Our prototype research was conducted on the Snake and Clearwater rivers using a shallow water hull design, that now has several beauty marks on the bottom from running in skinny rock infested water.
