5 DISASSEMBLY 1. Loosen end cap with Quicksilver P/N spanner wrench and remove piston rod assembly from cylinder. Ensure work area is clean before disassembling power trim cylinders. Cylinder parts can be damaged by dirt entering into power trim system. NOTE: Spanner Wrench Quicksilver Tool Part Number DO NOT clamp center section of power trim cylinder during assembly or disassembly. If clamping cylinder is necessary, clamp cylinder on front mounting flange. a - End Cap b - Cylinder c - Piston Rod Assembly 2. Remove DOWN trim hose from cylinder a - DOWN Trim Hose b - Clamping Plate c - Screws TRIM CYLINDERS - 5D-3

Be careful not to loose check balls. a - End Cap b - Piston Rod c - Large O-Ring d - Small O-Ring (2) e - Continuity Spring f - Rod Scraper g - Plain Washer h - Retaining Ring 6. Remove small o-ring from end of piston rod a - Bolt b - Flat Washer c - Spring Guide d - Spring e - Spring Guide Washer f - Check Balls (3) g - Shock Piston Assembly h - O-Ring a - Small O-Ring b - Piston Rod 7. Clean all parts in solvent. Be sure all parts are dry before reassembly. 5D-4 - TRIM CYLINDERS

7 Reassembly IMPORTANT: Later model Alpha One drive units use a trim cylinder that is 3 / 4 in. (19mm) longer, to achieve 6 additional tilt. Earlier model R, MR and Alpha One, as well as Bravo drive units, use the shorter trim cylinder. DO NOT attempt to substitute trim cylinders or damage to drive unit and/or transom assembly could result. Trim cylinders can be identified by a casting number on inboard side of trim cylinder. Shorter Cylinder: 98703, 98704, , Longer Cylinder: , Install small o-rings (c) and continuity spring (d) into end cap (e). 3. Install rod scraper (f), plain washer (g) and retaining ring (h) into end cap (e). 4. Install large o-ring (i) onto outside diameter of end cap (e). 5. Install end cap (e) onto piston rod. Ensure work area and all components are clean before reassembling trim cylinders. Power Trim components can become damaged if dirt gets into system. NOTE: Before reassembly, lubricate all internal parts with Quicksilver Power Trim and Steering Fluid or SAE 10W-30 or 10W-40 Motor Oil. 1. Install small o-ring (a) into end of piston rod (b) TRIM CYLINDERS - 5D-5

8 6. Install large O-ring (j) on shock piston (k). 7. Install check ball (l), check ball eyelet (m), spring (n) and spring pin (o) into shock piston. 8. Apply Loctite or Type A to threads of bolt being used in the following step. 9. Install shock piston, three check balls (q), spring guide washer (r), spring (s), spring guide (t), spring guide washer (u) and bolt (v) onto piston rod. Torque to lb. ft. (20-27 N m). 10. Apply oil to parts. Install o-ring (w) onto floating piston (x) and insert floating piston into cylinder (y). v u t s r l n m o x w y q J k D-6 - TRIM CYLINDERS

9 Ensure work area and all components are clean before reassembling trim cylinders. Power Trim components can become damaged if dirt gets into system. NOTE: Before reassembly, lubricate all internal parts with Quicksilver Power Trim and Steering Fluid or SAE 10W-30 or 10W-40 motor oil. 12. Position trim cylinder rear connecting ends as shown. DO NOT clamp center section of trim cylinder during reassembly. If clamping of cylinder is necessary, clamp cylinder on front mounting flange. Use only 2-4-C Marine Lubricant on end cap threads. Other substances may act as an insulator and cause poor electrical continuity between cap and cylinder which could cause a corrosion problem. 11. Apply 2-4-C Marine Lubricant to end cap threads and install piston rod assembly into cylinder. Tighten end cap securely using a spanner wrench. a - Port Trim Cylinder b - Starboard Trim Cylinder c - Connecting Ends (Angled As Shown) 13. Install DOWN trim hose a - End Cap a - Piston Rod Assembly b - Cylinder a - DOWN Trim Hose b - Clamping Plate c - Screws Check painted areas of trim cylinders for scratches that expose metal, paint if necessary TRIM CYLINDERS - 5D-7

10 Installation Use water and soap solution to aid in installing rubber bushings. The use of petroleum based product (oil and grease) can deteriorate rubber. 1. Install trim cylinder forward mounting hardware as shown. 2. Coat anchor pin threads with 2-4-C Marine Lubricant (to prevent threads from galling). 3. Hand thread locknuts onto pin. DO NOT tighten at this time a - Forward Anchor Pin (Longer) b - Washers (2) - Large I.D. c - Rubber Bushings (4) d - Washers (2) - Small I.D. e - Locknuts (2) f - Plastic Caps (Installed After Final Tightening of Nuts) a - Aft Anchor Pin (Shorter) b - Washers (2) - Large I.D. c - Rubber Bushings d - Washers (2) - Small I.D. e - Locknuts (2) f - Plastic Caps (2) - (Install After Final Tightening) Install trim cylinder aft mounting hardware as shown. 5. Coat anchor pin threads with 2-4-C Marine Lubricant (to prevent threads from galling). 6. Hand thread locknuts onto anchor pin. All 4 anchor pin locknuts must be tightened as described following or damage to sterndrive unit may result from drive unit moving too far inward. 7. Tighten 4 anchor pin locknuts until nuts and washers bottom out against anchor pin shoulder. 8. Reconnect trim hoses after air bleeding power trim cylinders and hoses following procedures outlined in Section 5A, 5B, or 5C (See Table of Contents). 5D-8 - TRIM CYLINDERS
