Everybody thought that Jet-boats looked cock as heckwitht heir shark
looking fronts, and giant 455 big blocks sticking up with chrome
risered exhause looking like the legendary Medusa. trumpeting and
making a lot of racket on the river. Interesting though, that with the
exception of the hole shot a 115 evinrude on a 17 foot glastron would
eat them on top end, and even as a 2 stroke, would do it on half the
fuel.

Sure busted a lot of egos.

considered thoughts to the readers of rec.boats:

Hello all,

I am thinking of getting a boat towards the end of this year. My wife
and I
have been looking at the Sea Ray, Maxum, line up in the 20 - 22 foot
range.
We have also looked at the Yamaha and the SeaDoo jet boats of the same
size.
The only difference I can really see between the two are the engines.
Both
types pretty much offer the same amenities. On the plus side for the jet
boats I see they have more horsepower (assuming standard engine) and
weigh
about half as much as a conventional boat. However, when out on the
water
you don't really see that many jet boats as compared to the thousands of
conventionally powered boats.

Is this because they have just not really caught on or is there some
underlying factor that I am missing ? Are the jet engines not as
reliable
as the more conventional I/O engines ? Anyway own one that would buy one
again ?

It is going to take about 100hp to get the same performance in a jet
boat that you would get with 50hp and a conventional propeller. Read
that: expensive to operate.

Personally, the only reason I would consider a jet is shallow water
operation in a flats boat.

Plus, jet boats handle weird...

Maybe in a jet Outboard, will you get a 50% efficiency. My Kodiak low
pressure pump is about 85% the efficiency of a prop and the new Hamilton
212's are about 95% efficiency. But with the Yamaha, SeaDoo's they are
running either a Rotex, very powerful, lightweight, and gas hog, or a
Sportjet, with a O/B powerhead to a crappy jetdrive. The Aluminum
jetboats of the Northwest are a lot better, but a lot more expensive. And
steering is great, as long as you have power. If in lakes and normal
deepwater, run a prop boat.


Thanks for the replies everyone.
