IMCO Xtreme Advantage SCX Series Installation guide

IMCO SCX SERIES INFORMATION, OPERATION & MAINTENANCE
1. SCX & SCX4 Drives will not fit on a standard gimbal helmet, IMCO HELMET:
#05-8025 Black or #05-8027 Silver or #05-8028 ITS Black is required.
2. Maximum engine idle speed is 800 RPM. Shift drive with a positive move, do not let clutch
sit between neutral and in gear position.
3. Do Not! Install propeller until the drive shift linkage has been properly installed and tested
with the engine running!
4. When using SCX or SCX4 drives it is necessary to have full hydraulic steering for your
safety.
5. When tuning engine remove propeller and shift drive into forward gear!
6. Do not run your boat with a worn or loose gimbal ring or helmet, worn clevis pins, or clevis bushings.
7. Every hull is different and requires a different setup: Many different things contribute to performance:
water pickup location, cavitation plates, gear ratio, drive height, prop, weight distribution, water conditions,
weather conditions.
8. If you are installing the drive on a new application, consult the manufacturer or a dealer with experience
with the hull to determine the proper drive height.
9. SCX Drive is 19 7/8” from crankshaft center line to prop shaft center line (2” shorter than standard
Bravo).
10.The bolt pattern is different from the SCX to the SCX4, lowers cannot be interchanged.
11. Max propeller diameter on the SCX is 16 3/4”, SCX4 is 17” (always check that there is at
least 1/2” clearance between the propeller blades and the drive case).
12.Large diameter propellers installed on a #6 prop shaft will require a torque tab on single engine boats.
13. SCX and SCX 4 drives require a drive oil reservoir with a minimum capacity of 1 1/2 quarts.
14.When installing drive to gimbal or lower to upper always use anti-seize on all threads.
15. When installing lower to upper, inspect all “O” rings, replace as necessary, pressure check to insure
proper seal.
16.If you do your own maintenance and repairs on your IMCO drive, you will need a service manual and
the proper tools.. Service manuals and tools are available at www.imcomarine.com/cal_store.
17. Always wear proper safety equipment when operating your boat, testing or running at high speeds.
18. Inspect for: oil level in drive and reservoir, leaks, loose fasteners, worn parts.
Recommended oil: Torco RTF GL-6 Torco Part #A220015CE (unit) Part # S220015C (case) IMCO Part #
09-2600 (unit) Part # 09-2605 (5 Gal.) Part # 09-2610 (case) (100% Synthetic Racing Transmission Fluid)
Replaces SAE 75W90.

Before Running!

To drain oil: remove drain screws form bearing carrier (right below the prop shaft) and on port side of
upper.
To replace oil: pump oil in from lower drain screw until it comes out of upper drain screw hole. Replace
drain screws and add oil to drive oil reservoir.
When changing oil, run the used oil through a strainer to check for metal particles, if there are metal
particles in the oil, it is time for inspection of the gears and bearings. If oil appears milky or off colored
check for leaks.
SCX, SCX4 capacity: 5 qts + reservoir - SCX Upper with SC Lower 4 1/2 qts + reservoir.
19. Drive must be turning before shifting.
20. Do not run engine when drive is trimmed extremely high, or in trailer tow mode.
21.Do not use solvents or chemical cleaner to clean painted surfaces on the drive.
22.When installing or changing propeller use extreme caution, propeller blades can be very
sharp.
23. SCX Upper vertical shaft is 17 tooth spline, SC, Merc lowers are 15 tooth spline. A 17-15 tooth
coupler is available 01-2150 (cannot be used with a spacer).
24. Use extreme caution if modifying lower, case can be weakened or handling can be
adversely affected.
25.Break in: Do not use full throttle until drive is fully warmed up, do not hold drive at wide open throttle
for more than 2 minutes for the first 3 hours of use.
26. Inspect anode (located on front of cavitation plate) for corrosion or debris; if necessary clean or
replace.
27. Do not shift drive while running on hose with propeller
installed.
28. Rotation: shift linkage pushed in - right hand rotation, shift linkage
pulled out - left hand rotation.
29. Serial # location: Port side below SCX,SCX4 sticker.

NOTE: Optimum performance of the upper gear case requires “setting up” the pinion & clutch gears with
IMCO procedure as follows.
1. Take all measurements using the “SCX Setup Diagrams” (Fig 3) and the “SCX Work
Sheet” (Fig 4).
2. After all measurements are taken and proper race thickness has been determined, place
lower race [2-6] and thrust bearing [2-7] in case.
3. Place lower clutch gear [2-13] with attached tool (backlash tower 01-5579) into case.
4. Adjust rolling preload (8-10 in/lbs) on pinion gear by changing Yoke Gear End Shims [2-42].
Tighten nut [2-36] to 75 ft/lbs.
5. After proper rolling preload is determined, assemble pinion pack with pinion retainer nut “O”
ring [1-20] between pinion seal carrier [2-45] and retainer nut [2-31].
6. Torque retainer nut to 200 ft/lbs. (Tool: Pinion Retainer Nut Driver 01-5590) (torque wrench
centered on retainer nut, or, if using longer tool be sure to compensate on torque value).
Use new lock nut [2-36] and torque to 75 ft/lbs.
7. Install pinion pack using 4 screws [1-23] for testing.
8. Install dial indicator (indicator bracket 01-5588) and pinion gear locking tool (pinion gear lock
01-5587) Fig-5.
9. Check backlash, adjust backlash with pinion hub shims [2-18] (average backlash should
be .007-.010).
10. Once backlash is determined. Check upper clutch gear by placing gear in lower position with
lower thrust race and backlash tower. This will insure backlash is .007 -.010 is correct on
upper gear.
11. Assemble drive shaft gear assembly [2-(8-17)].
12. Place the lower clutch gear [2-13] onto the clutch shaft [2-17], allowing it to rest on the thrust
collar.
13. Place the lower clutch spring thrust bearing [2-14] (silver side “up), lower clutch spring [2-15],
clutch cone [2-16], upper clutch spring [2-15], upper clutch spring thrust bearing [2-14],
(Note; use a thin layer of grease between the bearing and the gear to keep bearing in place
during assembly), (silver side “down”), upper clutch gear [2-13], clutch shaft retainer [2-9]
onto the upper clutch shaft [2-17].
14. Compress the upper clutch gear and install the upper drive shaft retainer keepers [2-8].
15. Install complete clutch shaft assembly into gear case.
16. Align the clutch gear timing marks (“+” over “-“, or “-“ over “+”) with the center of the rear face
of the gear case.
17. Install pinion pack with “O” ring [1-19] and shims [2-18] (shims must be properly aligned).
18. Torque pinion pack screws [1-(22-23)] (Important: make sure copper sealing washers [1-21]
are in place, short screws in 2 top holes & 2 bottom holes [1-22] longer screws in 3 port & 3
starboard holes [1-23] to 20 ft/lbs. Use “Loctite 242” on all screws. Note: make sure that the
clutch gear timing marks align to case timing marks, roll pinion to check.

UPPER GEAR CASE-ASSEMBLY

19. Place the shift yoke & cam assembly [2-28] into the clutch cone groove with the nuts facing
down.
20. Insert the shift link [2-24] with shift cable retainer [2-21] through front of gear case.
21. From the rear of gear case, place the small hole of the shift arm [2-22] onto the “pin” of the
shift link and secure with cotter pin [2-23]. (Be sure that the shift arm is positioned to except
the detent kit [1-31].
22. Install shift shaft [2-26] through the yoke & cam (note: use caution while installing to avoid cut-
ting seals) and shift arm [2-22].
23. Torque the 2 shift shaft screws [2-27] to 100 in/lbs. Use “Loctite 262” on screws.
24. Install quad ring [1-10] steering cap [1-2] including detent kit [1-31], insure “O” rings [1-29 & 1-
30] are in place.
25. Torque steering cap screws to 35 ft/lbs. Use “Perfect Seal” on threads.
26. Install quad ring [1-12] in steering cap, shift shaft plug [1-9], top cap “O” ring [1-13] top cap oil
pressure “O” ring [1-14]
27. Install top cap.
28. Torque top cap screws [1-8] (Important: short screws in 2 front & 2 rear holes [1-7] longer
screws in 2 port and 2 starboard holes) to 25 ft/lbs. Use “Perfect Seal” on threads.
29. Install oil tank cover [1-43], oil tank gasket [1-42] with “Permatex Form-Gasket 2’ (note: use a
very thin layer on gasket), oil tank cover screws [1-41] with “Loctite 242”, torque to 10 ft/lbs.
