It will be stamped on the prop on the side and/or at the hub depending on
brand. If you can't find it on the side of the prop, remove it and there
will be a set of numbers either at the front or rear of the hub.

Great advice as well. Thanks!

Now...how do I know what the pitch is of my current prop? The boat isn't
here, so if it's stamped on it somewhere, I can't check until tomorrow.

Thanks again.

There are also a considerable number of used prop sources including ebay.
The beauty of buying a decent used prop is that you usually can sell it
for what you paid. Or just save money. I keep several and change them
depending on what I want to do. Hole shot or top end. I use the low
pitch one for pulling the big guys up on the slalom or pulling multiple
skiers. Then you can keep one aboad as a spare too.

It will not filter any better.

Cool, that's really what I wanted to know.

For your application - I would consider a new prop.

Thanks! I'll look into it.

For your application you want your rpms to be at about 4600 at wide
open.
This will give you better fuel economy since you will get more speed at
less rpms.

Funny, I never looked at it that way. So, it's much like an airplane
that adjusts RPMs by changing the pitch of the prop?

Thanks again for the info.

your numbers you could go up 3" to 4" of pitch. Check a few prop shops
and just try one if they will let you. I think you will be amazed at
the performance difference.

Hi Tony,

I'm more interested in protecting the motor with a more efficient
filter *if I need to*. The boat is '95 Reinell 184 brxl. I've had it
to 50mph with three guys in the boat. That happened at about 5200rpm.
The manual says that WOT is between 4400-4800 rpm, which is where I
tend to run it. That get's me about 40-45mph. I have the aluminum prop
that came with the boat when I bought it. I'm not much of a skier, and
neither is my wife, so it's mainly cruising and tubing until my kids
are old enough to start skiing/boarding/whatever. By then, I'll
probably have a newer boat anyway.

That is a Stock engine (chances are). Save your money. You will get
much more performance from a prop swap.
What prop are you running now.
What is your max rpms at wide open trimmed out.
What is your max speed.
What type of boat to you have
What type of boating are you interested in (skiing, tubing, riding,
lots of people, just 1 or 2 people, top speed, acceleration)

A good SS performance prop setup for your rig can increase top speed
by 5 mph or more over a stock aluminum prop.

If your engine is bone stock, don't waste your money, the OEM units
are
fine.

I'm not sure if it's bone stock or not. I'm the third owner. Is
there a way to tell? It's a 4.3l Merc.

If you are into High Performance boating there are a lot better

I read recently that K&N makes a filter approved for marine
engines that
has
better flow and filtration than my old aluminum flame arrestor. Is
this
true, or just K&N hype?

Thanks.

Thanks Tony. I'll check it out tomorrow. Then I'll ask more questions g.
