There is stuff for outboards. There is some things you should think
about
too. Outboards are not engineered with a great deal of extra strength
in
the interest of limiting the weight. With any engine increasing the
output
is usally a trade off in longevity. Inboards are more forgiving in
this
respect that outboards just because there is more metal involved. The
other
thing is that it takea whole lot more hp to go faster. For example if
your
boat will do 50mph with a 150hp outboard on it, going 65 could take as
much
as another 50hp. It's not cheap to get an extra 50hp out of an 150hp
motor.
You'd be better off selling your 150 and buying a 200. I have a 300hp
small
block and my boat does high 60's. When it had a 205hp small block it
did
low 50's.

After watching Monster Garage on Discover (the one where they turn
a
pontoon boat into a shark dive boat) I got curious about an item
they
added
to the outboard. It was a nitrous system.
I have done a couple of web searches for outboard performance
accessories
but have only found
a wide selection of props. Is there any sites that deal with
outboard
performance upgrades?
Do them even make any aftermarket outboard performance gear?



There is considerable outboard performance gear available. See Bass and
Walleye Boats and the ads in there, among other places. Note that
modifying an outboard, except for racing motors, built after 1998 is
unlawful. might pollute the air.
