SeaArk's Jet Tunnel Hulls are designed to be used with a jet driven outboard. The Jet Tunnel design includes a flat roof in the tunnel to direct water back to the intake of the jet. The thrust of a jet outboard is about 70% of an equal sized engine with a prop. This fact and the fact that a jet uses water for propulsion instead of a metal prop, means that the operator loses some speed, directional control, and performance. What is gained with a jet is the ability to operate in extreme shallow water conditions without the fear of ruining a prop. Most of our customers using Jet Tunnel boats use them in shallow rivers where they need to pass through extreme shallow spots.
