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
Gates 9455 or Dayco 17455 or Goodyear 17456 or Mitsubishi 6455
•Yanmar part 129670 •Johnson 1027 BT in a pinch
Usage Worksheet Description Amp/Hrs per Day Lighting: interior, anchor light/3.6 Refrigerator/55.6 Stove (after initial start)/1.6 Computer/phone charger on Inverter/22.8 Electronics (typically used while underway)/25.3 Water pumps and Fans/5.4
Total: 112.6 amps hrs/day
Charging/Storage Worksheet Alternator Output: 80 amps Time to recharge house batteries with alternator: 4.5 hours Engine Start Battery, Group 27, 105 amp Thruster/Windlass Battery, Group 27: 105 amp House Battery Bank: use-able capacity: 450 amp Number of days able to run on house battery:3.8
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
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
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.
