Fuel economy of older jet boats

Oh, about the SeaDooDoo Islandia powered by 2-stroke jetski engines....

Never talk about "mileage" around jetski-powered boaters. They just get
angry.

A properly tuned SeaDooDoo 2-stroker can eat 14 gallons per hour PER
ENGINE.

Don't forget to carry your VISA. You're gonna need it!

Though not as "cool", Mercury Sport Jet 2-strokers aren't so high
performance, trying to squeeze every rev out of a too-small jetski engine
whining away at high RPM to produce power. In a Sea Rayder 16' jetboat,
the 175hp, 6-cylinder Sport Jet will guzzle around 14-20 gallons a day,
especially if you drive it like you stole it or pull skiiers for hours.

Jet boats are VERY inefficient power plants for anyone interested in fuel
management.
