This is the equipment, food and clothing reminders that we use to prepare the Laurie Ann for a 7 day or longer boat trip. Our planning strategy is to re-supply once every seven days to get the local food and goods.
Boat Exterior & Engine
Fuel tank: Rule of 1/3: never let the tank be less than a 1/3 full when planning how much fuel to get
Check both tool bags, both repair boxes, coolant and oil?
Racor filter checked?
Belt checked, 3/8 inch deflection is desired; more means tightening
No Wake and engine cool down speed is 1,400 RPM or less
Maximum fuel efficiency is 1,600 RPM which is hull speed of 5.5
Poorest fuel efficiency is 2400-2800 RPM
Turbo starts to kick in at 2400 RPM
Engineered cruising speed, unlimited time, and cleans turbo and heats up oil is 3,100 RPM. 13-14 MPH with ideal conditions; run at least 20 minutes per day
Alternator reaches max charge of 14.25 volts at 1,200 RPM
120 volt battery charger starts at 15 volts and adjusts accordingly
Battery Volt Meter; Selector Switch:
Left or 1 is Engine Battery
Middle or 2 is Thruster & Windlass
Right or 3 is House Batteries
Temperature Readings Using Infra-red Sensor
Oil Filter: 180-260
Stuffing Box: less than 20 degrees above water temperature
Raw Water Difference from water temperature, entering & leaving: 10-25 degrees
Wet Exhaust parts: 90-140 degrees (none more than 200)
Instrument Gauges
Fuel Gauge is accurate, ½ means 37 gallons
Temperature: 175 degrees is when thermostat opens, anything less than 190 degrees is normal, higher temperature indicates impeller is worn or obstruction in cooling system
Oil Pressure: 55-58psi at 1500 rpm is normal, less pressure at lower rpm is normal
Fresh water tank sensor: 2/3 means half full; 1/3 means quarter full
Engine Controls
Start with key, Stop with kill switch
If engine does not turn over, the cause is the neutral safety switch in the gear shift-wiggle the gear shift when it is vertical
If engine will not stop at kill switch: use manual kill switch on engine block, I painted it red
Wallas Stove
Stove is hard-wired to House battery bank with a stand-alone 20 amp blade fuse and is labeled at the house bank
If stove does not start in two attempts, it will automatically “lock up.” Fix is to pull the fuse, wait a few seconds, re-insert
Use kerosene at least once a year to clean the unit. Do not store it for over a year in the tank.
Windlass & Anchoring (65 feet depth capability)
Scope of 1:3 is normal, use more for conditions
Windlass pulls about 1 foot per second
Rode: 260 feet: 25 feet of chain and 240 feet of rope
Rode Markings: four stripes is 40 feet; six stripes is 60 feet; 8 stripes is 80 feet; Color change at 100 and 200 feet
Cold Weather Storage Precautions
Chairs, BBQ, dinghy, and outboard are stored indoors
Water tank at least half full
Diesel tank half full
Batteries receive a charge once a week
Use oil-filled space heater (no flame) and keep cabin at least 45 degrees
Use yellow, plug-in thermostat sold for heat tape that turns at 35 degrees and off at 50 degrees
Open bilge access plate in head
Open engine access at door step
Open head door
Two golden rods, 120 volt heat, under engine
Run cabin heater fan to keep air circulating at fresh water pump and water tank when temperatures are in the low 20’s or less
Do not boat unless the air temperature is mid-30's or higher for 12 hours (damage impeller)

Maintenance Procedures
Oil Changes:
Raise boat on trailer to get engine level.
One absorbent pad in the bilge, another folded and under the oil filter
Have five rags ready to cover engine compartment and deck.
Have garbage bag ready for pads, rags and filter
Heat oil by running engine at least 20 minutes
Open oil filler cap to prevent vacuum
Suck out oil with vacuum tank-will take two full processes
Use filter wrench labeled “Yanmar” to remove oil filter
Fill oil with 5-6 quarts of 15-40W diesel oil from cabin side and check oil level with dipstick.
Run engine for 5 minutes to check for leaks. Let stand for 10 minutes before checking oil level again.
Racor Fuel Filter Change
Absorbent pad under Racor filter
Use filter wrench, labeled Racor
Drain clear reservoir into custom-made pan
Use filter wrench and push toward the bow to loosen filter
Change filter and use new gaskets: o-ring between bowl and filter, black gasket between filter and housing
Put fuel from custom pan into Wallas tank
Use Yanmar bleeding system to draw fuel into bowl before starting engine: Loosen bleed screw, wrap rag under bleed screw and use thumb pump on top to pump out any air in line
Yanmar fuel filter
Remove step wall and set aside the coolant reservoir
Loosen clamp on the heat shield
Disconnect electrical connection between the sensor at bottom of filter and the wire from the port side by pressing on the white piece.
Use 13mm socket on a ratchet and remove the two bolts holding filter assembly at the top
Remove the heat shield and take electrical connection through it and set it aside after wiping it out. Then, loosely put the assembly back together with the two bolt so you have leverage to unscrew the filter with a wrench.
Filter is full of fuel but can be removed while full, put rags around the top, lay one pad underneath, have Racor can ready
Use black spanner wrench labeled filter wrench to unscrew filter
Pour fuel into Wallas stove tank & use funnel
Put old filter on work surface
Unscrew white electrical connection and re-attach it to the new filter but be careful for cross-connection; press down vertically while slower screwing on
Re-assemble and reconnect
Open the bleed screw with two turns and finger pump, 15-20 times to purge air and fill filters with new fuel.
Run engine for 10 minutes, checking for leaks
Battery Maintenance:
Check water level in cells once a month
Use hydrometer to check health of each cell in the spring
If significant water is needed or a cell is weak, remove battery and charge it separately from the bank for at least 24 hours and re-check cells after waiting 24 hours
Impeller Replacement:
Put pad over door sill to lay on
Have flashlight on and position on engine mount
Use hose clamp socket on ¼ inch drive ratchet
Close seacock valve.
Remove four bolts on cover
Use angled needle nose pliers to grab fins of impeller. Pull on each side and wiggle. Takes 10-15 minutes to remove impeller.
Lube inside of new impeller with a non-petroleum product
Follow Yanmar manual on direction of impeller. Turn and insert. Use thumbs to push on the sides and wiggle. Takes 5 to 10 minutes to insert.
Try to use old O-ring. New ones are hard to keep in the groove.
Replace cover. Open seacock valve and start engine to check for leaks.
