I run a Jetcraft 21' Bluewater and get about 1.75-2 mpg depending on
throttle opening. Mostly WOT. You might also look at the Willy boats
Predator. It is also a Sportjet powered boat. I have heard that the
Harbercraft's are not as good as the former Jetcraft's (they bought jetcraft
and moved it to BC). Call Willy boats and ask them. Mine is a 1991 Kodiak
pump, but I understand the newer Hamilton's are about 95% of a prop boat
now.

Guys,

I am thinking about getting a harbercraft jetboat ... these things are
made from aluminum and have the 175 HP Mercury sportjet..

So far so good ... Now what raises the fuel warning flag are the
terms:

- jet
- 2 stroke
- carburator (two of them

The boat will burn about 5 gallons per hour at 30 mph... now I was
wondering how this compares to a similar sized fiberglass hboat with
115-150 HP 4 Stroke outboard..

What is the fuel you burn at cruise speed and WOT, whats your boat
size/weight and what motor are you running ..

I am interested in how the relatively light alu jetboat compares to a
more conventional boat with 4 stroke motor..

Any info is appreciated


Matt
