INSTRUCTIONS To eliminate unnecessary work, careful reading of the applicable section is recommended before starting to service a bumper boat. Photographs, diagrams, notes, cautions, warnings, and detailed descriptions have been included wherever necessary. Nevertheless, even a detailed account has limitations; a certain amount of basic knowledge is also required for successful work.
Page 4: Specifications
CIRCLIP, RETAINING RING Replace any removed circlips and retaining rings with new ones, as removal weakens and deforms them. When installing circlips and retaining rings, take care to compress or expand them only enough to install them and no more. COTTER PIN Replace any cotter pins that were removed with new ones, since removal deforms and breaks them.

Page 134: Basic Electrical Troubleshooting
BASIC Electrical Troubleshooting Whenever testing for power (voltage) flow in the circuit, the FIRST order of business is to establish and verify the test unit is functioning properly and has a solid ground. When possible, attach the ground lead of the tester directly to the ground post of the battery pack.
Page 135 2) EVERYTHING HAS RESISTANCE. The wires, connectors, and switch contacts that make up a circuit all have some resistance and, as its name implies, resistance opposes (resists) current. In an undamaged, properly designed circuit, normal resistance is small enough that it doesn’t keep the load from working. UNWANTED RESISTANCE IN THE CIRCUIT REDUCES THE AMOUNT OF ELECTRICAL ENERGY DELIVERED TO THE LOAD.
Page 136: Voltage Drop Test
Voltage Drop Testing The battery pack contains four 6-volt, deep-cycle lead-acid flooded-type batteries connected in series to produce a 24vdc “pack.” 4-gauge copper cables are used to connect the pack and furnish power through the main breaker switch to the main distribution buss. Use the voltage drop test to check the battery-terminal- to-cable-end and battery-pack-to-breaker-switch for excessive resistance.
Page 137 Open-circuit problems such as broken, disconnected wires and/or connections stop current flow. After you fix an open circuit, switch the circuit on again and check for lingering voltage drop. Until you get current flowing and check the circuit again, you can’t know if the entire circuit is healthy. Although resistance-free connections, wires and cables would be ideal, most of them will contain at least some voltage drop.
Page 138: Testing Fuse
TESTING FUSE TESTING PROCEDURE FOR FUSE It is extremely important to understand that if a fuse looks good, it might not in fact be good! Fuses can appear to be fine and have a break in them so small that it cannot be seen by the naked eye. Therefore, it is important to check a fuse with an ohmmeter or a continuity tester instead of assuming that it is good.
Page 139: Major Electrical Components
MAJOR ELECTRICAL COMPONENTS J&J battery-powered bumper boats utilize a simple 24VDC circuit containing the power pack, consisting of four 6VDC deep-cycle, 225 amp hour batteries wired in a series. 50 amp breaker/switch #2-60-0102 Power post, negative junction Battery Battery Battery Battery The cables and wire harnesses connect the components in the circuit.
Page 140 Testing: Use the DVOM and perform voltage drop tests to troubleshoot the wire harness and connectors. The unique portion of the wire harness system, the flex wires, allow the motor to rotate 320 degrees while maintaining current flow to the motor system. The system is designed to eliminate as many connectors as possible and avoid problem areas, while providing a simple, trouble-free unit.
Page 141 The motor portion of the wire harness connects the solid state, magnetically-triggered on/off switches to the power relay, motor and squirt pump with a corresponding ground wire circuit to complete the loop. Kartrol Micro #1-60-8000 White lead from Kartrol unit Fuse Black lead to negative post #2-70-0104...
Page 142 4-10 The magnetic trigger is a high-quality, neodymium magnet housed in an injection-molded holder that is designed to be loose when properly mounted, but not able to rotate. This is required, as there is top side and a bottom side to the unit. The bottom side must face toward the solid state switch.
Page 143 4-11 J&J’s exclusive high-efficiency, brush-type, permanent magnet motor is directly activated through the relay; because this outboard-style unit operates in water, no “ramp up” is required. How a simple DC electric motor operates: When the coil is powered, a magnetic field is generated around the armature. The left side of the armature is pushed away from the left magnet and drawn toward the right, causing rotation.
Page 144 4-12 A SIMPLE, EFFECTIVE AND PROVEN SYSTEM The J&J electric bumper boat utilizes four Trojan T-105, 6V Batteries rated at 225AH, and connected in series. This battery pack was chosen to provide the best performance-to-weight ratio and has proven, since its introduction in 1996, to have an excellent record of performance and durability.
Page 145: Specific Gravity Test
4-13 SPECIFIC GRAVITY TEST <CAUTION> MAKE SURE YOU WEAR GLOVES AND EYE PROTECTION WHILE PERFORMING THESE TESTS. 1. Do not add water at this time. 2. Fill and drain the hydrometer with electrolyte from battery cell 2 to 4 times before pulling out a sample. (See the Hydrometer battery tester on page 5-148) 3.
Page 146 4-14 <WARNING> A brand-new battery may have a low electrolyte level. Charge the battery first, and then add water if needed. Adding water to a battery before charging may result in overflow of the electrolyte. J&J recommends topping off the batteries once a week; with the J&J fill kit working properly, you cannot overfill the cells. WHAT IS THE PROPER ELECTROLYTE LEVEL? (IF YOU ARE USING J&J FILL KIT, THE FLOAT VALVES WILL SHUT OFF AUTOMATICALLY AT THE PROPER LEVEL) Liquid levels should be 1/8 inch below the bottom of the vent well (the plastic tube that extends into the battery).
Page 147: Equalizing Batteries
4-15 Equalizing Batteries Lead plates become sulfated as a natural result of their function; breaking this deposit loose and keeping the plates “clean” will equalize each cell’s ability to do its work. Equalizing is an overcharge performed on flooded/wet batteries after they have been fully charged. This action “scrubs” the plates, and the sulfates will fall to the bottom cavity of the battery.
Page 148: Battery Maintenance-Winter Storage
4-16 Battery Maintenance - Winter Storage 1. On the days before leaving, do a thorough cleanup of connections and batteries. A mechanical inspection will help you to identify what terminals need replacement, and maximize the recharge rate. 2. Fully charge your battery systems. If possible, use your chargers in a low-amperage mode. It will take longer to fully charge the batteries, but will do a much better job.

For this reason, J&J Inc. has prepared this information on how to properly condition your bumper boat fleet for periods of storage or inactivity.
Page 164 FIBERGLASS CARE AND MAINTENANCE WHAT IS FIBERGLASS? Fiberglass is a common term for fiber-reinforced plastic, or FRP, which is a plastic material strengthened using a fiber cloth. Most boats these days are made from fiberglass, along with pickup truck caps, motorhomes and even bathtubs! To give the fiberglass a smooth, shiny surface, a material called gelcoat is applied to the outer surface.
Page 165 CLEANING FADED OR OXIDIZED FIBERGLASS There really isn’t any secret to cleaning faded or dull fiberglass; you just need some elbow grease and something to remove the oxidation. The application varies for different products, but in general, you need to rub the surface with the oxidation remover or polishing compound to remove the oxidized layer.
Page 166 303 AEROSPACE PROTECTANT BUMPER BOATS - MAKE THEM LOOK BETTER AND LAST LONGER WITH 303 An enlarged side view of common vinyl fabric would show raw PVC (polyvinyl chloride) covered by a thin layer of plastic called the “topcoat”. The topcoat is the part of the vinyl you can see and touch. To keep vinyl fabric soft and flexible, manufacturers add agents known as plasticizers to the raw PVC.
Page 167 303 FOR FIBERGLASS: Never buff or wax again! Like vinyl, gelcoat fiberglass (polyester resin) is a UV-sensitive plastic. Though manufacturers add UV stabilizers to vinyl and gelcoat fiberglass in the manufacturing process, these protective agents weaken over time and must be replenished if continuing UV protection is desired. Colored gelcoat fiberglass is particularly sensitive to UV degradation, and 303 Protectant is by far the easiest way to make colored fiberglass look like new again, and to keep it that way.
Page 168 STORAGE BATTERIES When your boats are not in use and your park is closing for the season, it is a good idea to winterize your bumper boat batteries. To do this, there are a few steps to follow in order to maximize your batteries’ life. The first is to fill each battery up with water and fully charge each battery;...
