Jet boats in small rivers!!!

[Avalon]

I've only had outboard powered boats, so I'm no expert on jet powered motors.
The only time I was in a jet powered outboard was with Guide Bob Toman on the lower Deschutes.
He had a 200 hp Merc jet.
I was immediately alarmed with how NOISY his motor was, as we powered through the current.
It sounded like a crazy washing machine!
I realized that Bob's motor was working much harder as a jet than it would be as a motor with a prop attached.
Controlling the boat is different also.

Dear DShock,

You were probably in a 2-stroke jet outboard, a 4 stroke jet outboard is much more quiet.

The motor doesn't run any faster or make more noise with a jet pump than it does with a prop. Jets are 30% less efficient than a prop, but they don't produce any more noise with an outboard. 5000 rpm at the powerhead is 5000 rpm regardless.

Best Wishes,
Avalon

Avalon,
You are right! I have never been in a boat with any motor other than a 2 stroke.
I was at a boat ramp one day and watched people trailering their boats. The motor that most impressed me was the Honda 4 stroke.
The new outboards are amazing engines.
