Crowley Marine

APPLICATION

This kit is designed for use on the following 2-cylinder outboards with manual tilt: 2004 and newer Evinrude® E-TEC™ 40 HP recreational and 60 HP commercial models and 1982 and newer Evinrude®/Johnson® 40-60 HP models (including 55 HP commercial and 55 HP military models) with single-piece lower motor cover.

SAFETY INFORMATION

For safety reasons, this kit should be installed by an authorized Evinrude/Johnson dealer. This instruction sheet is not a substitute for work experience. Additional helpful information may be found in other service literature for your engine. This instruction sheet uses the following signal words identifying important safety messages.


Indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.


Indicates a potentially hazardous situation which, if not avoided, CAN result in severe injury or death.


Indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate personal injury or property damage. It also may be used to alert against unsafe practices.

IMPORTANT: Identifies information that will help prevent damage to machinery and appears next to information that controls correct assembly and operation of the product. These safety alert signal words mean:

ATTENTION!
BECOME ALERT!
YOUR SAFETY IS INVOLVED!

Always follow common shop safety practices. If you have not had training related to common shop safety practices, you should do so to protect yourself, as well as the people around you.

It is understood that this instruction sheet may be translated into other languages. In the event of any discrepancy, the English version shall prevail.

DO NOT do any repairs until you have read the instructions and checked the pictures relating to the repairs.

Be careful, and never rush or guess a service procedure. Human error is caused by many factors: carelessness, fatigue, overload, preoccupation, unfamiliarity with the product, and drugs and alcohol use, to name a few. Damage to a boat and outboard can be fixed in a short period of time, but injury or death has a lasting effect.

When replacement parts are required, use Evinrude/Johnson Genuine Parts or parts with equivalent characteristics, including type, strength and material. Using substandard parts could result in injury or product malfunction.

Torque wrench tightening specifications must be strictly followed. Replace any locking fastener (locknut or patch screw) if its locking feature becomes weak. Definite resistance to turning must be felt when reusing a locking fastener. If replacement is specified or required because the locking fastener has become weak, use only authorized Evinrude/Johnson Genuine Parts.

If you use procedures or service tools that are not recommended in this instruction sheet, YOU ALONE must decide if your actions might injure people or damage the outboard.

TO THE INSTALLER: Give this sheet to the owner. Advise the owner of any special operation or maintenance information contained in the instructions.

TO THE OWNER: Save these instructions in your owner’s kit. This sheet contains information important to the future use and maintenance of your engine.

INSTALLATION INSTRUCTIONS - STARBOARD SIDE STERN BRACKET WITH LOWER PIVOT PIN HOLE

IMPORTANT: Use the following instructions if your outboard has a hole for the lower pivot pin bored all the way through the starboard side stern bracket.


To prevent accidental starting while servicing, disconnect battery leads from battery. Twist and remove all spark plug leads. To prevent injury from contact with a rotating propeller, remove propeller before servicing.


During service, the outboard may drop unexpectedly. To avoid personal injury, always support the outboard’s weight with a suitable hoist.

Remove thrust rod.

Remove nut, washer, and stop link screw from port side stern bracket. This will loosen the stop link so you can access the upper pivot pin hole.

Remove nut, washer, stop link screw, and spring washer from starboard side stern bracket. The spring washer is located between the stop link and the stern bracket.

With both stop links loosened, there will be enough tilt play to install the tilt assist cylinder. 

Install two (2) bushings in end of cylinder.

IMPORTANT: During installation and assembly, apply a light coat of Triple-Guard® grease to all pivot points.

Position cylinder between stern brackets. Insert upper pivot pin through port side stop link.

Install two (2) washers on upper pivot pin. Install two (2) cotter pins in upper pivot pin holes. There are four (4) holes in upper pivot pin. Depending on engine model, use innermost available holes.

Install lower pivot pin through hole in starboard stern bracket to secure other end of cylinder.

Use allen head wrench to install set screw into lower pivot pin hole until screw bottoms out.

Install previously removed spring washer, stop link screw, washer, and nut through stop link and stern bracket on starboard side. Make sure the spring washer is installed between the stop link and the stern bracket. Tighten nut to 144 to 168 in. lbs. (16 to 19 Nm).

Install previously removed stop link screw, washer, and nut through stop link and stern bracket on port side. Tighten nut to 144 to 168 in. lbs. (16 to 19 Nm).

Install thrust rod.


When the tilt assist cylinder is installed, the thrust rod cannot be installed in the lowest position. The thrust rod must be installed in one of the other positions. Otherwise, the outboard’s reverse thrust lock will not engage and/or the cylinder may be damaged.
 

CHECK OPERATION


Use the tilt grip on the engine cover to tilt the outboard. DO NOT use the steering handle to tilt the outboard.

Before delivering to customer, make sure outboard tilts fully up and down and turns freely from side to side. Also, make sure reverse thrust lock engages fully.
