READ THIS IF YOU’RE CONCERNED ABOUT, OR
HAVE EXPERIENCED, HIGH PERFORMANCE
STERN DRIVE FAILURE
It’s time to face facts. If you’re a performance boater putting more
than 500 horsepower to your stock Bravo drive, you’re inviting
trouble. And more than likely, you’ve already experienced one or more
drive related failures related to high output horsepower and torque.
Isn’t it about time you stopped hoping for a band-aid miracle and
solved the problem once and for all? Here’s how to do it.
After more than a decade of designing, engineering, testing, racing
and manufacturing high performance stern drive products, IMCO has
a staff of stern drive application specialists at your disposal. Give us
your accurate horsepower, torque, gross weight, prop, gearing and
hull type, and we’ll gladly recommend the correct IMCO drive best
suited for you.
IMCO offers three unique stern
drive solutions, including the
brand new SCX, the strongest
and most reliable high
performance cone clutch
option ever. If you’re
serious about performance
boating and eliminating the
“weak-link” give us a call.

The lack of a clutch cone meant the drive
needs a way to shift. A Borg-Warner Velvet
Drive transmission has been incorporated into
the extension box. The engine remains in the
stock Bravo location as shown. (Also available without extension box, engine moves

Xtreme Advantage SC not only makes the
difference on how fast you go,
it makes the difference
on how far you go!
The Billet Aluminum top cap is supported by eight
bolts with a controlled water-circulation
system and built in spray nozzles to provide
maximum cooling to the external upper gear case.
IMCO Xtreme Advantage drive is the only drive available with
both upper and lower steel towers.
IMCO has developed a rigid pinion and bearing pack assembly
with non-elastic shims to provide the correct rolling torque
while stabilizing both input yoke and pinion. Tightened to 75
lb/ft, the pinion assembly is held in place by our plated steel ujoint retainer nut through a direct load-bearing path.
NET FORGED UPPER GEARS
The steel tower in the floor is stabilized through internal
lateral support beams to eliminate tower flex and gear
deflection.
3” SHORTER MID SECTION CAVITATION PLATE
STEPPED UP FOR PROPELLER CLEARANCE
IMCO is the only manufacturer at this time that can offer four
vertical lengths and three exterior finishes. See our lower section for more information.

STOCK UPPER
Our Xtreme Advantage SC drives are also available as upper
units only, for those who may already own a IMCO, or a stock
Bravo lower. Servicing can be performed by any qualified
Mercruiser repair shop, no need to send back to the manufacturer. This means more time on the water.

NET FORGED LOWER CASE GEARS

Net forged, straight gears are 40% stronger than Bravo spiral
cut gears. Thicker upper gear floor provides structural integrity
to handle more torque.

U-JOINT RETAINER NUT
01-4223
The IMCO plated steel nut has a far superior fit and strength over a stock cast
aluminum nut. The nut works as its
own tap to cut tighter fitting threads,
so you don’t have to worry about it
coming loose and throwing off the
backlash. This is a MUST for all
Bravos.

XTREME ADVANTAGE LOWER UNITS
PROP SHAFTS
Hydro dynamically designed, cast aluminum lowers have been
reinforced in all the critical stress areas for improved strength
and durability. Designed with a unique oil passage that provides
for lower oil temperatures, less bearing, and gear wear, and
greater reliability. With the extended leading edge, the Xtreme
Advantage lower reduces slip, prop blowout and drag. The
internal design allows for more air to pass through the propeller
hub, reduces drag which greatly improves top end speed.
IMCO prop shafts are made from non-corrosive aerospace
alloy. Standard diameter, 1” prop shafts are available for
stock Mercury bearing carriers or IMCO billet bearing carrier,
IMCO billet carriers triple the stock load carrying capacity.
ULTRA HEAVY-DUTY
DOWN SHAFT
IMCO’s precision engineered one
piece vertical torsion shafts are
made from an aerospace allow,
designed to absorb the load created by hi-pitch props used today.
Available in four sizes, standard length, 1”, 2” and 3”.
For extreme duty, you need to use or Xtreme 11/4” or new 17/16”
diameter. The 11/4” has 60% more material in the cross sectional area at the prop spline and the 17/16” has 75% more. These
shafts can be retrofitted to a stock lower gear case. You can use
your square bore propeller with a Mercury prop adaptor (11/4”
prop shaft) or the IMCO prop adaptor (17/16” prop shaft).

HOW TO ORDER
IMCO’s custom aluminum fuel tanks are made to fit your needs.
We have over 30 years of experience in assisting marine manufacturers (as well as the individual consumer) throughout the
western United States. We use our unique race-proven methods
to build a tank to your specifications.
Gunnel Tanks
Note in the photographs throughout this section, we use radius
bends to eliminate surface cracking in materials normally
caused by sharp bends. We use rib-bending to prevent oil canning which causes metal fatigue.
Step 1 (Top View): Measure length and
Our unmatched
welding
process
allows for maximum
strength. We use seamwelding to prevent stress
on the surface of the tank.
The ends of our tanks are tig
welded (heliarc) for maximum fill and penetration.
IMCO’s welded baffle process is unmatched in the marine industry.
We employ an exclusive double-skinned procedure which ensures
width. Allow 1⁄2” of clearance for length

line depth and stringer depth.
The fuel tank covered by this warranty was produced by IMCO (Inman Marine
Corporation), and it is warranted against defects in materials and workmanship for one
year from the date of its first consumer sale, whether by IMCO or by any other marine products dealer or seller.
LIMITATIONS: This warranty is expressly conditioned upon the tank having been properly
installed and under proper usage for which the tank was intended. The terms of this warranty shall not apply to any case where any unauthorized repair or work has been done upon
the tank.
IMCO fuel tanks are designed strictly for pleasure craft purposes only. Any tanks used in
crafts other than for pleasure purposes will not be covered in any way under this written warranty as set forth herein, and IMCO in no way will be liable or responsible for any damages.
It is expressly provided that IMCO shall not be responsible for consequential inconvenience,
injury, or damages; and that no warranty, expressed or implied, other than this written warranty is made or authorized by IMCO.
Notwithstanding the foregoing, some states do not allow certain limitations, or exclusions may
not apply when the laws of such states are controlling. Furthermore, this warranty gives the
buyer specific legal rights, and the buyer may also have additional rights which vary from
state to state.
WARRANTER PROMISES: In the event that the fuel tank, to which this warranty applies,
fails to comply with the terms of the warranty set forth above, IMCO agrees to either replace
or repair any part or parts which are defective in materials or workmanship, or IMCO agrees
to refund an amount not in excess of the factory purchase price of said part or parts. The
decision as to which of the foregoing remedies is allowed shall be made in the sole discretion
of IMCO upon the following principles: IMCO will in all cases elect to either repair or replace
such a part or parts unless
a) IMCO is unable to provide a replacement and/or repair is not commercially practical or
cannot be timely made, or
b) IMCO and the consumer mutually agree upon a refund as set forth above, except as provided hereafter with respect to certain allowable cost incident to replacement or repair, and
with respect to the remedy for a defective sender. The foregoing shall be the exclusive
remedy offered by IMCO under this warranty.

PROCEDURE (A): A consumer may write or call directly to IMCO in order to describe the
nature of the claim, or
PROCEDURE (B): A consumer may present his/her claim to the dealer from which he/she purchased the IMCO product (or to any other IMCO dealer). In order for a claim, made in this

When a claim has come to the attention of IMCO in either manner as set forth above, the
consumer or dealer must give the date the tank was manufactured and the date the boat was
purchased. IMCO will at this point determine whether the claim is covered by the warranty as set forth herein, and IMCO reserves the exclusive right to make this determination.
If the claim is covered by warranty and the consumer has followed procedure (A) above,
IMCO will instruct the consumer either to send the defective merchandise to IMCO, freight
collect, or to deliver the defective product to a specific authorized IMCO dealer, who shall
be informed of the work which IMCO will perform under the warranty, or to pursue such
other reasonable course of action at the expense of IMCO, which IMCO in its sole discretion shall deem most practical in satisfying its obligations hereunder.
PROCEDURE (C): If the consumer desires, the following additional claims procedure is
available, but the burden of all costs incurred pursuant thereto, prior to approval of the
claim by IMCO, must be borne by the consumer, who is subject to possible limited reimbursement as set forth hereafter. Under this procedure, the consumer must return the defective product directly to IMCO freight prepaid. If upon receipt of the defective product,

These high performance manifolds are unique in design, that
creates a high velocity airflow that increases torque, rpm, and
horsepower over stock cast iron manifolds on both small block
and big block. We have experienced 40 to 50 foot pounds of
torque on big block 502, 415 horsepower motors, and 80 to 90
foot pounds of torque on engines up to 575 cubic inches.
Powerflow manifolds are water-jacketed, water surrounds each
exhaust passage, including the ports to eliminate burnout. Black
manifolds are hard anodized prior to powder coat, to ensure against
corrosion. All manifolds are available in Recirc or standard.

Shown in the picture is a good pipe template sent
in by a customer. This template shows us where
the water inlet goes, the location of the pipe in
relation to which engine and which side. The
flange in this case is a CMI and is properly fixed
to the template. (We can build a pipe only as good as the template.
A small error in the header or manifold end is a huge error at the end
of the pipe) Take your time with the template.

IMCO has spent hours engineering and developing this outstanding product. In testing this product, we have found that the propeller creates a vacuum through the propeller hub and wishbone,
which is adequate for medium speeds, but for top speeds, more
power is required, and better exhaust flow. Sound Advantage
provides better flow, and more power with a touch of a switch
for both big block and small block.
This system is unique because of its simplicity. Unlike other systems created by other manufactures that are either wide open or
closed at all times, Sound Advantage can be opened to any position for any amount of exhaust flow and sound at any time. Our
unique worm gear drive requires a 12-volt supply and an optional switch sold separately. All Sound Advantage systems for
Mercruiser, IMCO Powerflow, and IMCO Stainless Steel Risers
for Mercruiser are powder coated black. Exhaust tips sold separately.

When using these systems with
Mercruiser 8.1, Powerflow or
Thumper Power, and Corsa,
you will need to order two each
02-2242 oval hoses for wishbone to “Y” pipe connections.
Low profile system for Mercruiser, IMCO Powerflow, Thumper
Power, and IMCO stainless steel replacement riser pipes are
designed for low profile boats as pictured. This system has a
180-degree bend, and sweeps 90 degrees down as pictured. This
allows the exhaust tips to be installed low and outside of the
stringers. Switch and exhaust tips sold separately. Please specify big block or small block when ordering.
