Are Jet boats good in the ocean?

While you find a "Jet Pump" boat interesting and in you're price range, they are TERRIBLE on fuel usage. You can run the boat in the saltwater, but a boat with a standard outdrive will perform way better than a jet boat. This is why you don't see any ocean "go fast" boats that are jet drive. Only lake and river boats are jet drive. They waste a lot of fuel and lose lots of speed in rough waters like in a saltwater bay due to cavitation of the pump.

Boats For The Ocean

what nobody is telling you is that jet boats are bullet proof,meaning they have less problems to worry about.With outboards and inboards you have to worry about props,saltwater intake and winterizing.With a jet it is a closed system it has a heat exchanger so no water intake to cool engine the prop is internal and protected and you don't have to winterize it.As far as fuel consumption goes it all depends on how much you run and how fast.I have a alexis classic with a 5.7l and a 9.9 kicker motor i troll a lot and use the kicker most of the time I have had gas in that tank for over a month without refueling.If your going to be flying up river all the time then fuel is irrelevant also because only a jet is going to fly up the river anyways.

They are really really good in thin water and restricted waterways. On wide open areas they are only more efficient than a correctly set up out drive or leg at high speeds, 50 knots plus. With a modern diesel they are reasonable on fuel, big petrol engines will not be so good compared to a conventional drive system.

About 50MPH

It would work on the ocean just drain and rinse the boat with freshwater when finished.
