Re: 1993 Evinrude 50/35 HP Jet Opinions
I've been running outboard jets for 10-12 years now. My engines are larger than what you're thinking of, but that's just a matter of degree.
Like someone above said, all outboard jet units, regardless of the make of the engine, and regardless of whether they're installed (and painted) in the factory or after market are made by Outboard Jet

I need a jet because I often run in very shallow water. My 21 foot, 6 foot wide welded aluminum boat with a 200 hp Johnson will run in about 6 inches of water when it's on step.
But, the horsepower loss is easily 30%, which means slower speeds and/or poorer gas mileage.
Performance has a lot to do with set up and hull design.
If you need a jet, they're great. If you don't, they're a waste of fuel and power.
