With further improvements down the years, water jet proved to be more advantageous than propellers for a wide variety of vessels. This was the beginning of the popularity of jet boats and jet units. Unlike the previous attempts at water jet developments like the Hanley Hydrojet and Campini’s, Hamilton was specifically targeted towards developing a propulsion system that could operate efficiently in shallow waters. This was specifically designed to overcome the problem of propellers striking rocks.īefore Hamilton, there were many attempts at making water jet propulsion but were not lasting mostly because the design of the units were inefficient and did not prove to be better than the conventional propellers. Sir William Hamilton originally developed jet boats back in the year 1954 for use in the shallow and fast flowing rivers in New Zealand. With propellers, these boats can perform their signature 360-degree spins. With a massive jet boat like a Shotover, you can travel at an impressive 85 kph in waters as shallow as 10 centimeters. The first jet boat did not have any propellers so that it would be able to navigate very shallow rivers that New Zealand is known for. It has water intake systems that are similar to jet skis. These boats do not operate like regular motorboats. They also make an ideal choice for family watersports like waterskiing, wakeboarding, and tubing.Ī jet boat is one of those crazy adventure sport boats that was originally developed by a New Zealander. These boats tend to be smaller and are commonly used for navigating in inland waterways like lakes and rivers or in areas near the shore. With a jet boat, you can get multiple seating rooms with enough space to move around the boat thanks to the compact engines. Make sure the water is a couple of inches deep and has no obstructions. You can easily take your jet boat stern in and walk out into the beach without having to swim to land.
These jet boats can have drafts as short as 14 inches (SX190 Yamaha) and 34 inches (19 Sport Sea Ray).
One of the biggest factors here is safety without a prop at the back, anyone can swim or tube near the stem without worrying too much.Īnother thing about jet boats is that you can practically take them any place because they have less of a draft. Unlike the conventional prop and outdrive used in water boats, jet boats are powered by single or double engine configurations with an impeller that sucks water in through a grate in the hull and propels the boat. These watercraft are uniquely different from your traditional water boat. With these jets, you can drive at exhilarating speeds, enjoy unparalleled maneuverability and boast leap onto planes without holding back. I have put 80hrs on this motor pump combo this summer and have not ever been disappointed or let down yet!” Kyle Johnstun 852X / 6.If you are looking for high-performance, thrilling water rides, jet boats are the way to go. I can slow to a crawl mid rapid and go WOT to blast in-between wave trains to make a smooth run-up with a blip of the throttle with no-slip whatsoever this 852x pump never stops pushing me up the river. I have a lot more confidence in big water now. In the rapids of Hells Canyon/Snake/Salmon river I am in love with this boat all over again. The adjustable trim nozzle took care of all my balance and porpoise problems.

I can haul a full load of people and gear now and I hardly even notice the extra weight. First trip out with the family fully loaded boat (coolers, food, fuel, 2 kids, a dog, etc) I was equally impressed fast, nimble and beinng loaded up didn't change a thing. “First impressions were "wow this thing is quick!" My boat would instantly get on step and topped out at 52mph with the 111mm nozzle insert. “Every time I run this setup I know it will take me anywhere I want to go with ease”
