What Arneson Industries Can Do For You
Reliability, Very few moving parts means very few things go wrong.
Efficiency, Very low parasitic drag means more of your engines HP going to the water.
Speed, Low drag design means the boat is getting maximum efforts of your engine horse power.
Fuel Mileage, With a 30% speed increase, you can go 30% faster at the same engine rpm which translates into better fuel mileage for your boat.
Lower Maintenance, With fewer moving parts than conventional propulsion systems, typical maintenance is down to 200 hour oil changes and electrolysis anode replacements.
