ADDITIONAL COMPONENTS FOR INSTALLATION

To complete the installation of your outboard, you will need the following items. Your Briggs & Stratton Dealer has kits available to aid installation. See an Authorized Briggs & Stratton Dealer for available Power Supply Harness kits, which include the battery harness and fuse supplies.

•Line Fuse, fuse block & cable caps. Connect fuse as shown under Battery Installation. Use appropriate cable caps to protect the fuse block terminals.

•Battery Harness. 6 gauge wire or larger, terminating in an Anderson SB120 (or equivalent) connector, to connect the batteries to the outboard.

•Deep cycle marine batteries. Briggs & Stratton recommends using four 12 Volt batteries. Refer to a marine battery manufacturer or dealer for specific information.

•U.S. Coast Guard approved battery boxes.

•6 gauge wire battery cable inter(connects.

Please refer to the Battery Recommendation and Battery Installation sections for further information on proper battery connection.

OUTBOARD

INSTALLATION

OUTBOARD PLACEMENT

Fig. 3

When determining conformity to

WARNING boat weight limitations, take into account the weight of the out$ board AND battery pack.

Follow the boat manufacturer's recommendations to install the

outboard to the boat.

The capacity plate on the boat shows the maximum horsepower allowable for your boat. DO NOT exceed this limit.

1.Center the outboard Ê on the transom Ë.

2.Be sure the anti$ventilation plate Ì of the outboard is positioned below the bottom Í of the boat.

3.Tighten the clamp screws Ï to secure the outboard to the transom.

CAUTION: Inspect clamps periodically for tightness to prevent engine from loosening off of transom. Do not allow

any part of motor or shaft to rub or be in contact Îwith the transom.

4.Adjust the tilt pin to obtain a vertical position for the outboard. See Outboard Trim Angle.

5.Test the range of steering motion ¼. No part of the gear case or propeller should contact the transom.

OUTBOARD TRIM ANGLE

Fig. 4

Follow the boat manufacturer's instructions for the correct trim angle. The outboard has five trim positions Ê. The ideal trim angle allows the anti$ventilation plate to run parallel Ë to the water surface.

WARNING

DO NOT attempt to adjust the trim

 

 

angle while the outboard is run$

 

 

ning.

 

 

If the bow of the boat is above horizontal Ìput the tilt pin in a lower adjustment hole to move the outboard closer to the transom (example from hole A to hole B or C).

If the bow of the boat is below horizontal Íput the tilt pin in a higher adjustment hole to move the outboard farther from the transom (example from hole E to hole D or C).

OUTBOARD TILT

The outboard can be tilted to gain clearance and avoid lower unit damage when landing the boat in shallow water.

Note: The outboard cannot be locked in the UP/ TILTED position.

Tilt the outboard using ONLY the TILT/CARRY HANDLE Îat the rear of the outboard. Pull the TILT/CARRY HANDLE in the direction Ï as shown to tilt the outboard.

Lower the outboard slowly AFTER the boat has come to rest.

REMOTE CONTROL INSTALLATION

Refer to instructions included with remote steer kit.

BATTERY

RECOMMENDATION

The outboard requires a 48 volt power source. For best results, use marine group 31 deep cycle batteries with at least 100 ampere hour rating. Your outboard can draw 70 amps continuously with the throttle set at MAX POWER, and as much as 100 amps for short periods of time. The actual ampere draw is subject to your particular environmental and operating conditions.

Refer to a marine battery manufacturer or dealer for specific information.

Speed Setting

Note: Run time and speed will vary based on battery size, boat hull size, type and loading, and water conditions.

Cycling batteries are designed to have good life performance in deep cycle service. The major cause of battery failure in deep cycle service is poor maintenance:

•Dirt and corrosion on battery tops or terminals

•Incorrect battery water level

•Lack of charging

•Excessive discharge

Maintain battery pack at full charge. Proper care will signifi$ cantly improve the battery life. Failure to properly recharge batteries (within 12$24 hours) may cause reduced battery performance or premature battery failure. For best results, use a variable rate charger.

Refer to the battery charger manufacturer for specific informa$ tion on how to charge the battery pack.

BATTERY HARNESS

INSTALLATION

Risk of Electrical Shock. DO NOT

WARNING touch un$insulated battery termi$ nals, connectors, or wires.

Prior to wiring the batteries, en$ sure that the battery harness is unplugged from the outboard.

Batteries must be connected in series to obtain 48 volts with 100 ampere rating.

You need to purchase three 6$gauge battery cable inter con$ nects. The battery connection diagram is for reference ONLY. While the connections will follow the pattern as shown, the ac$ tual position of the batteries may vary depending upon how and where the batteries are located within your boat.

Use the following procedure and follow diagram to harness the batteries.

Fig. 5

1.Using a separate interconnect for each battery, connect the positive(+) lead from one battery to the negative(-) lead on the next battery. The batteries will then be connected in series, with a single positive(+) and negative(-) lead left open at each end of series.

2.Tighten the battery terminals to 130 lb(in (15 Nm), or as specified by the battery manufacturer.

Note: This outboard is equipped with an AndersonR

connection Ê terminal. The line fuse Ë is lo$ cated on the positive (+) lead side. Connect the positive (+) lead to the open positive terminal of the battery series. Connect the negative (-) lead to the open negative terminal of the batteryseries.

3.Connect the positive(+) lead of the battery harness to the open positive(+) battery terminal.

4.Recheck all connections to ensure they match the wiring diagram prior to plugging the battery harness into the outboard.

5.Keep wire connections to the batteries tight, maintaining good contact with the battery terminals.

Note: The battery connection diagram is for reference ONLY. It depicts four 12 volt batteries wired in a series to produce a total of 48 volts.

WARNING

Improper wiring of batteries could

 

 

cause batteries to explode.

FUSE BLOCK CONNECTIONS

Fig. 6

•Remove Fuse Block Cover Ê.

•Remove cable mounting screw and nut Ë from block terminal.

•Attach fuse link cable Ìto terminal.

•Repeat, attaching the harness lead to other terminal.

•Before tightening cable screws, slide fuse Íinto block.

•Tighten screws and replace cover.
