lazarette. These are attached with suction cups directly to the hull. Have an oil/fuel absorbent ready to soak up
any spilled fuel. All windows and ports should be closed to minimize fuel odor. You should have a rough idea
of how many gallons you will need to keep from filling too fast and spilling over the deck or spewing from a
vent. As the tank fills, the sound will rise in pitch or gurgle. With a little practice you can tell by the sound
when the tank is nearly full. It is a good idea to have a crew member watch the pump meter and tell the skipper
when it is near the expected amount but several gallons before the expected amount is pumped.
The fill tubes on occasion will burp back when filled too fast and this can be very messy. Wrap the nozzle with
an absorb right at the filler while pumping the fuel to contain any back splash.
Some marina pump hoses are not long enough to reach both tanks from across the deck. One way to get to both
fuel tanks, without moving the boat, is to open both pilot house doors and pass the fuel hose through the pilot
house. Please be very careful when doing this to avoid spills in the pilot house cabin. Completely wrap the
nozzle with an absorbent and have a crew member guide the hose from inside to prevent contact with settees,
walls and carpets. If diesel is spilled inside the cabin it can be a downer for your vacation as it is very difficult
to remove the odor and expensive to clean from furniture and carpets.
Replace the deck fill caps, check your fuel gauges and turn on the engine room blower for several minutes, this
may be done while you go and pay. Clean up any spatter and wash hands thoroughly.
• DO NOT TRUST FUEL GAUGES. As a policy, top off the tanks approximately every 15 engine hours.
This leaves a margin to guarantee you will not run out of fuel. The port tank feeds the port engine and
the starboard tank feeds the starboard engine and the generator so it may take slightly more fuel.
• RACOR fuel filters are mounted in the engine access under the top step next to the galley. Inspect them
whenever you are in the engine room. Water will appear separate from the fuel and can be drained out
the petcock at their bottoms. A little dirt is okay but if they look dirty call AYC to change the filters.

4 Electrical System

GENERAL:
The Bayliner 4788 Pilothouse has an electrical system that requires special understanding. Before reporting any
system failure, search for that system's second or even third switch. There are many redundancies. For
example: the depth sounder circuit on the DC main circuit board must be on. Also the depth sounder switch on
the flybridge to the left of the wheel must be on.
The electrical needs of a Bayliner 4788 Pilothouse can be very high. Therefore you may need to prioritize use
of some appliances and these should only be used when others are turned off. Pay attention to the amperage
meter on the main circuit board to keep tabs on the amperage draw. When plugged into a single 30-amp shore
power, do not exceed 30 amps draw. The biggest amperage users are the water heater, the electric stove and the
inverter may draw very high current if charging the house batteries.
Note that if you have two separate power sources you may configure up to 60 amp by setting the main panel
rotary switches to "normal" vs. "parallel" settings Line 1-2 and/or Line 1-3. You will likely need to pay an
extra fee to the marina for this extra power.
