Exclusively manufactured by a ISO-9000 and MilSpec certified aircraft manufacturer.

Our Mission:   In an effort to provide you with a solid product that will give you years of dependable service with a minimum of maintenance we have rigorously tested our product over 1700 hours in  all possible conditions without one failure. The system is so basic that it worked the first time out and just kept performing.  This is why the Patented TriBox Propulsion system comes with a 2 year/ 500 hour unconditional guarantee.

When designing Tri Box, we had three main goals in mind,  to provide a system that would give superior performance,  offer exceptional economy and better dependability than its gas counterpart.   We have achieved our goal and you can expect to cut your fuel consumption in half while paying up to 25% less per gallon for diesel Vs. gas.  With safe dependable diesel power and Tri Box Propulsion, your vessel responds instantly to your commands - forward, reverse or both. Spin the boat like any twin screw vessel. Since the conversion to TriBox uses much larger propellers you'll enjoy better economy and more control when docking.  Wind and tide become problems of the past.

Regardless of the vessel configuration, if you have twin gas engines connected to inboard Vdrives,  straight drive's or inboard/outboard, TriBox will match or in most cases outperform the gas engine configuration at the specified cruise speed.

Please take a few moments to view all of the information on this site.  We have provided a customer inquiry page for you to fill out providing us with the necessary information to assist you in determining the proper horsepower and prop size for your vessel.  This information can be E-mailed to us or we can take the information over the phone.  Do not hesitate to call us if you have any questions.   Again thank you for your interest in TriBox Propulsion, Inc.

Sincerely,

Donald A. Milne III, President
