J/46 OWNER GUIDE 7 Getting Started With Your J/46 Generally, your dealer or commissioning yard will help you prepare your boat before launching. And in most instances with a boat this size they will undertake the entire commissioning job. They are experts in the field and are capable of completing most commissioning tasks. Before Proceeding Before you begin to assemble your new boat you should become familiar with the different sail control systems and associated hardware.
J/46 OWNER GUIDE 8 • Insert all lifeline gates/stanchions into the sockets provided along the toe-rail. Secure each stanchion in place by tightening the two set screws in each base. We recommend that you dip the screws in blue Loctite or sealant before securing, so they don’t work themselves loose over time. • Install all lifelines without tightening the turnbuckles. Remove the eyes at the ends of the lifelines and thread them through in the stanchions.
J/46 OWNER GUIDE 9 Rudder Stock Stuffing Box: is located at the top of the fiberglass rudder tube beneath the decks. It is a simple design which prevents water from entering the hull. A stainless sleeve bearing surface surrounds the rudder tube at the point where a rubber seal is forced against it to prevent water from rising up the tube. Emergency Tiller: is operated by lifting off the access plate (amidships), and placing the base of the tiller over the head of the rudder stock.
J/46 OWNER GUIDE 10 Jib Controls Jib Halyard: exits the mast on the port side, runs through a turning block at the mast collar aft to the organizer, and then leading into the halyard/secondary winch. Jib Sheet: is attached to the headsail by a bowline knot and led aft to the jib car on the jib track then aft through the foot block to the primary winches. If a large genoa is used, the sheets lead outboard of the shrouds to the aft genoa car, then through the foot block and to the winch.

J/46 OWNER GUIDE 28 Tuning The Rig Tuning the Mast Please refer to special manufacturer instructions for the optional Hall carbon fiber mast included at the end of this guide. • The standard headstay length is designed to allow sufficient rake for good upwind balance with either small or large jib. The Harken MK III Unit 2.0 furler fits the standard –17 rod headstay. The backstay is set-up with a toggle under the hydraulic cylinder to set the handle forward and the release knob aft.
J/46 OWNER GUIDE 29 Engine System The engine and fuel system is engineered to be conveniently accessible for repairs and general maintenance. Located aft of the companionway ladder. There is access to the front, sides and back of the engine from which all important functions can be reached; including water strainer, fuel injectors, fuel filter, fuel primer, expansion chamber, and alternator.
J/46 OWNER GUIDE 30 Fuel System • Fuel Tank & Hoses: The J/46 is equipped with two fuel tanks for a total 90gallon capacity. The primary 60gallon tank is located under the quarter-berth. A secondary tank is located on centerline aft below the steering cables. This 30gallon tank gravity feeds into the primary tank. Fuel lines run from the primary tank to the fuel primer pump. From there fuel flows into the injectors. The tanks themselves are aluminum and baffled to prevent fuel slosh.
J/46 OWNER GUIDE 31 General Hints To Avoid Problems • Monitor brightness of cabin lighting and charge batteries as required by running engine. Batteries are charged by either the AC battery charger or by running the engine. NEVER START THE ENGINE WITH SHORE POWER CONNECTED • Stop engine with throttle fuel cut-off, then turn ignition key “off”. • NEVER turn engine battery switch to OFF position while engine is running. • For best efficiency and fuel economy a cruising R.P.M.
J/46 OWNER GUIDE NEUTRAL= Between Forward & Aft REVERSE= Pull Aft 32 Push in throttle button at center of handle and move throttle lever forward 1/3 to increase initial starting RPM's. • Turn ignition key to "ON" position. Audible alarm indicates low oil pressure, and will continue until engine starts. There is an oil pressure alarm test switch on the cockpit engine panel. • Turn the ignition key to the "START" position. Release immediately after start.
J/46 OWNER GUIDE 33 • Shut off all equipment: Engine, Battery Switch, Radios, Lights, Etc. • Remove fuel fill plug and clean threads of both plug and deck plate carefully so no dirt falls into filler opening. Place the fuel hose nozzle into the fill pipe. • Fill slowly. DO NOT OVERFILL. Marine fuel expands with an increase in temperature. Thus, fill only to 95% capacity. If you cannot see the fuel pump, ask the attendant or a crew member to call out the total gallons. l.
J/46 OWNER GUIDE 34 Plumbing Systems General The plumbing systems in your J/46 consist of fresh water, manual and electrical pumps, and the heads (toilets). This section will describe their locations and how they operate. Fresh Water System Water Tanks: are made of rotationally molded polyethylene.
J/46 OWNER GUIDE • 35 Bilge Pumps are both electrical and manual. Two pump intakes are located in the keel stub under the main cabin floor, with a third intake attached to a coiled hose in the aft head. This is long enough to reach the bilge and qualifies under ORC cat 2. • The Manual pumps are operated from the cockpit and from the aft head. • Electrical Bilge Pump is wired to an independent switch on a recessed panel adjacent to the nav station.
J/46 OWNER GUIDE 36 • Electrical Panel: is built by Bass and controls electric distribution with circuit breakers and switches. The main wiring harness runs from the back of this panel. • Mast Wiring Terminal Box: is located in the shower compartment on the bulkhead. A wiring harness exits the mast near the box, and is wired directly into the D.C. system through a terminal strip. Once this wiring is installed, test each function to insure proper operation.
J/46 OWNER GUIDE 37 Galley Stove LPG System Liquid Propane Gas (LPG) is the most common fuel used for boating and is available at most marinas in the U.S. The Force 10 stove is of very high quality and is engineered for the marine environment in highgrade stainless steel. It is comparable to a home range. The biggest difference is safety.
J/46 OWNER GUIDE 38 Safety Lightning Protection The J/46 is completely grounded in accordance with industry practice. The mast, shroud chainplates, stemhead fitting, backstay fitting, stanchion bases, engine, and electrical system are grounded to the keel. In spite of this grounding, there can be no assurance that personnel or the boat will not suffer injury if the boat is hit by lightning. The following are suggestions only and in no way guarantee safety in the event of a lightning strike.
J/46 OWNER GUIDE 39 Maintenance Tips Even though modern construction has helped reduce upkeep, regular attention should be given to the maintenance of your boat. This includes the fiberglass exterior surfaces, the interior wood surfaces, and the mechanical and electrical systems. A well maintained boat will not only bring you years of enjoyment, but most importantly, will bring you greater personal pride and joy.
J/46 OWNER GUIDE 40 Deck Hatches Hatches need lubrication of their hinges with a silicone grease once a year. Also check the seals to see they are not unduly cracked, or are losing their ability to seal correctly. To increase traction on the plastic hatch covers, apply a non-skid tape fore and aft. Cabin Ports The ports are made of acrylic and are highly impact resistant. However, avoid highly abrasive cleansers which can scratch them. Instead, use mild soap and water to clean ports.
J/46 OWNER GUIDE 41 Annual Maintenance Checklist Running Rigging ___ Check running rigging lines for wear at splice, turning blocks, etc. ___ Inspect blocks and shackles for wear . Clean and lubricate or replace as necessary. ___ Service winches, check for free spinning operation(bearings) and ratchet stop action(pawls). ___ Re-caulk chainplates. Deck Hardware ___ Check lifeline integrity, stanchion, and rail attachment to deck. ___ Check all cleats for signs of fatigue.
J/46 OWNER GUIDE 42 Storage Tips Many of the maintenance problems surrounding boats can be pinpointed during the end-of-season haul-out. This is the time when a careful inspection will reveal the ravages of a long summer. If you live in colder climates, it is also the time to prepare the boat for what might be an even more brutal winter ashore. First, clean your boat as thoroughly as possible. Get the yard to use a high-powered hose to clean off most of the growth before it dries onto the bottom paint.
J/46 OWNER GUIDE 43 Interior & Ventilation Clean the cabin thoroughly with a damp rag, for any salt left behind will breed mildew. Clean out the head and sinks. Any paper items- books, toilet paper, notepads- should be taken off so they don’t mildew and rot. Leave the dorade vents in place and open so the boat can circulate fresh air. If a winter cover is used, it is good to leave the hatches cracked open to enhance air circulation. This helps prevent mildew. Also, remove boat cushions and store indoors.
