In a Sea Rayder 16' jetboat, the 175hp, 6-cylinder Sport Jet will

That statement is useless without a time factor better than 'per
day',
Eight hour day would be maybe 2 gallons per hour. I don't think that
is what you meant.

Really, and 14-20 gallons wouldn't be that much for any boater with
an engine around that size who ran at a high cruise or was pulling
tubes or skiers.


You don't pull skiers, wakeboarders or tubes at high cruise.


Try reading the sentence again, braindead.


"...ran at high cruise *or* was pulling tubes or skiers."


My experience is that pulling a skier/tube at 3000 rpm, or a
wakeboarder at 2200 rpm would burn about the same or maybe slightly
more than running at 3400 without towing anyone.


What have you noticed when you are pulling skiers/wakerboarders and
tubers?


What I noticed is you cannot properly decode a simple sentence.


So are you saying there is *no appreciable difference between cruising
at 3400 rpm and pulling water toys at 2200-3200?


Could be IMO. * Depends on the boat and how it is powered.


It also depends on many other factors such as number of passengers
aboard when doing 3400 rmp and pulling water toys at 2200 rpm.

All things being equal, I doubt pulling folks in water toys and in the
boat at 3200 rmp is the same fuel burn rate as cruising with with
those folks at 3400 rpm.- Hide quoted text -

I find that pulling people tends to burn more fuel than cruising at
any speed. It's the getting up on plane quickly a lot that eats up
the gas. Also because it's often my teenager and her friends and they
tend to explore the limits. Which means they end up not on the end of
the rope anymore a lot.
