assistant: All the ones I've seen say that they reduce cavitation and help the boat
to get up on plane faster and easier.
    This is all well and good but, why do I need to reduce cavitation? Am I
hiding from a Soviet submarine? Am I going to give away my position or
something?
    Me having a 26' pontoon that will do 45MPH, I don't have any problems
with porpusing (sp) so I really don't see where having a hydrofoil will help
me.
    Anyone have info that will set me straight?

assistant: Jamie Adams wrote in a message to Tim Morgan:
I doubt that they reduce "cavitation", which is the formation
of bubbles out of the water itself due to a too-fast spinning of
your propeller thereby creating vacuum near the blades.  This
causes pitting and erosion of the propeller.  By providing a
larger barrier over the propeller the fin may reduce "ventilation",
which is the sucking of surface air down to the propeller.
What these hydrofoils are supposed to do, is help to get your
boat on a plane quicker, which is important to skiers.  They
essentially act as a trim tab, and if your boat is properly
balanced you probably don't need one.  On the other hand, if
the device you are talking about is not properly trimmed, it
may worsen your boat's performance.

assistant: I'm only assuming here, but by the explanation you give above, wouldn't
cavitation actually slow you down a small amount too?  If there's air near
the prop, there isn't water.  Also if there is a vacuum isn't that sucking
against your boat as well?
    I agree with you that I probably don't need it, for several reasons.  One
being that I have a pontoon boat and there's not a lot of things available to
me to enhance my performance.  Probably keeping my motor in tune will do the
most.

assistant: My boat is a 21' Fish/Ski that has real bad cavitation problems right now.
The prop that I have is the culprit. It is a 3-blade Raker with a 24 pitch.
I can be running along and all of the sudden the prop starts to cavitate
and then it slips. After talking to other people, I can say that the Raker
prop from Johnson is a terrible prop for most boats.
I have seen one hydrofoil that claims it will also reduce Porpusing. I have
seen it popping up in most of the boating and fishing magazines, like Bass
Pro, Overtons, and Cabelas. It says it was rated number one by some boat
magazines. I have a problem drilling into my motor to install something
unless I am sure it is going to have a positive effect. 45MPH in your
pontoon boat is really moving. My Cajun will only do about 52MPH.

assistant: I think you're fixing to tell me how cavitation hurts. Is it because
there is less water and more air around the prop and therefor you get less
push?
    That's where I saw this one. I got an Overton's catalog and my Boat US
had it in there too.
    Yes sir! I do agree with this statement. I don't like the idea of doing
anything to the boat unless it's definately gonna be productive or make the
baot appreciate in value.
    I have a 150 Eveinrude Intruder on the back. It'[s actually pushing
around 180-195 horses.

assistant: With my prop it also causes Ventilation to occur, and I have to almost stop
the boat to get the prop to catch it's bite again. A real pisser coming
from a new $20,000 boat and motor. I am about to have a serious talk with
Travis Boating Center about this little issue.
I expected more out of my 200 Johnson. I think much of the problems are
with the prop though.

assistant: Is there an override for the tilt/trim on a 200hp Johnson Outboard? I just
got back from the lake and my motor will not go back down. It is stuck all
the way in the up position. The tilt just makes kind of a stuttered whine,
but the motor does not move at all. I am going to take it in for service,
but I was wondering about the future. Like what might have happened if I
had tilted the motor up while on the lake and had it stick like that 5
miles from the ramp. Thanks...

Question....What rpm are you turning at Wide Open Throttle? Saying
redline is 5500 and your running WOT 5000 you have a fuzz to much prop.
It sounds like it's breaking loose. This could be a loose hub or to low
a pitch prop.

If this is the same boat above it sounds like it's either drasticaly

have less than a 175 on it....It needs a 200..at least.

assistant: Jamie Adams wrote in a message to Alex Vasauskas:
The vacuum is negative pressure on the convex side of the blades.
It's the same negative pressure that causes an airplane wing to lift
and a sailboat to move by sucking the wing or the sail in the direction
of the negative pressure.  When this negative pressure becomes great
enough, it causes vapor bubbbles to form, which erode your prop.
Since this negative pressure is on the convex side of the prop blades,
I would expect it to suck the blades in the direction of travel, but
the loss of bite of the prop from the too-fast spinning for too little
movement forward would act against this in addition to inefficiently
driving the boat forward.
Keeping your motor in tune and your boat in trim sounds like your
most cost effective approach to the same end result -- and your
boat will be more seaworthy than using the quick fix of "curing"
an out of trim boat with what is essentially a trim attachment
for you engine.
Bests,
Alex

    This is what I was thinking. It seems to me that if these things were

hit 4800, which seems a little low. I could live with the performance as it
stands, if it was not for all the blow-outs I get. When I took delivery on
the boat, I questioned them about the 24 pitch 3-blade Raker and they
assured me that it was the best setup for that 21' boat/200hp motor. The
dealer said to bring the boat by and we would discuss the problem. I can
tell them right now that I am not going to shell out 400 dollars for a new
prop unless they take this old one back in full trade value. I'm going by
to see them this weekend.
