Compiled by Norm Perron 11/18/02  (items with * indicate changes since version 01)
Performed Recommended Maintenance Item
date/hours Interval  
     
Engine    
  Each sail date Check engine oil level, coolant level, visual inspection for any fluids in the well; with engine operating check oil pressure, 
    coolant temperature and alternator voltage
  About every 25 Engine water strainer--Clean and remove debris
    hrs or each  Shaft Packing Gland--Depending on type installed, it should be visually inspected for excessive leaks
    time in engine    The standard gland should drip one drop every minute at rest and once every 15 seconds while in gear
     room V belt--Inspect for hairline cracks, if find any, replace immediately. Buy a spare
    Exhaust Riser--Look for corrosion,hairline cracks or water. Remove/inspect, probably replace, they last about 5 yrs
  75-100 hrs Change oil & filter
  100 hrs Water Pump Impeller--Inspect, especially if temperature gauge rises
  150 hrs Transmission Oil--Replace, most 4JH2E use same oil as engine
  300 hrs Fuel Filters--Replace both, this is a great time to practice bleeding the fuel in case it needs to be done out at sea
  300 hrs Valve Adjustment--Be sure engine is cool
  300 hrs Water Pump Impeller--Replace, keep best looking one as a spare
  Every 2 years Engine Coolant--Yanmar recommends Texaco Dexcool (orange, don't use green coolant, in Yanmar)
     
Interior    
  Quarterly Flooded Batteries--Check water, add distilled and fill to split "rings", clean battery posts
    Gel/Agm Batteries--Make sure battery post are clean and tight
  Quarterly Toilets--Pour about 10 ounces of vinegar in toilet & pump 1/2 of it out (let it sit as long as possible)
  Quarterly Pumps--Run all pumps-especially macerators & sump pumps, be sure to "open" the discharge valves
  Quarterly Sea Cocks--Work each one (move handle open/colsed a few times)
  Semi-annually Bilge--Cleaned and dried & bilge pump run to make sure works, the manual pump should be hand pumped as well
  Semi-annually Rudder Bearing--Inspect for leaks and/or cracks every time you are in the lazarette or every 6 mos depend on use
  Semi-annually Mast--Check base for corrosion and standing water
  Semi-annually Windlass--Spray T-9 (or equivalent) on below deck portion of windlass
  Semi-annually Electronics--Check for firmware updates, especially Garmin GPS
  Semi-annually Propane--Check for leaks, after use, turn off solenoid, close valve, should retain pressure for at least 1 hour
  Semi-annually Batteries--Equilize to shake deposits off the cells
  Semi-annually Hose clamps--Inspect hoses for abrasion and check clamps for wear and make sure they are tight 
  Semi-annually Check mast deck boot for leaks*
  Annually Pedestal--Oil (use engine oil) wires & chain, be sure less than 1/2" deflection per exposed foot, grease needle bearings
  Annually Portlight and Deck Hatch Gaskets--Apply silicone grease to all gaskets
  Annually Fresh Water Tanks--Sterilize (with chlorine), flush, sweeten (with baking soda) and flush
  Annually Fire Extinguishers--Be sure all guages are in middle, take off bracket, shake vigorously, break up caking (dry chem)
  Annually USCG Courtesy Marine Exam--They go through most safety items, be sure to check any CO2 tanks inside life
      jackets, dates on flares and replace expired ones
  Annually Anti-siphon Valves--Take off top fitting, blow into hole on top, be sure air can get through
  Every 3 years Windlass--Change gear oil
     
Exterior    
  Each sail date Running rigging--Visually inspect for chafe and fraying, rinse hardware & deck/hull with fresh water
  Each use Rinse/soak anchor rode with fresh water*
  Bi-monthly Sea Cocks--Check to insure they are clear and free from marine growth
  Bi-monthly Zincs--Check zincs for wear, replace any more than 75% consumed
  Quarterly Stainless and Lifelines--Clean and wax
  Semi-annually Mast--Check for corrosion around all dissimilar metals, inspect each fastener/cotter pin to be sure not coming out
      At that time, clean the shrouds (Seapower & rag seem to work quite well) and mast, for anodized spars, use Alumaguard
  Semi-annually Standing rigging and turnbuckles--Look for meat hooks and cracks, if any, replace, or replace after 12 or so years
  Semi-annually Blocks & running hardware--Lubricate with McLube or Dry PTFE spray
  Semi-annually Furling Gear/Bearings--Fresh water rinsed getting to the bearings, (find the string "furler" on the C42 discuss forum)
  Semi-annually Windlass--Grease cones
  Semi-annually Dodger and canvas--Lubricate zippers and snaps
  Semi-annually Lubricate mast track*
  Annually Dutchman--inspect lines for wear, replace if badly thinned, adjust for no slack with neutral boom and tight topping lift*
  Annually Running Rigging--Wash them in a machine w/cool water, fabric softner and extra rinse. Air dry.
      Inspect for chafe or fraying, if possible (no splice), reverse the ends
  Annually Hull & deck smooth surfaces--Waxed, after 5 years it should be compounded
  Annually Winches--Clean with kerosene, re-grease, be sure to use light oil on pawls
  Annually Canvas Snap Fittings, Lifeline Fittings & Deck Hardware--Apply corrosion block, especially anodized hardware
  Annually Check shroud tension and balance--tighten if necessary, also check forestay & backstay, lube all turnbuckles*
  Annually Inspect anchor rode for wear, loose shackle pin, may need to re-splice line to chain*
  Annually Inspect shore power connection for corrosion/overheating*
  Bi-annually SS screws that go into aluminum backing plates--Re-bed with an anti-seizing compound
      Those that are tough to get to (those that attach sheet stoppers), work them by unscrewing them part way & re-tension
  Bi-annually Sails--Have washed and inspected by your sailmaker
  Bi-annually Bottom painting--Or Tri-annually if you're lucky
     
Haulout    
  Sea Cocks Lubricate from the outside w/Lanocote stuffed in a drinking straw, take the hose off & do the same from the top
  Props Lubricate and check bearings on folding and feathering props
  Zincs Replace as needed
  Cutlass Bearing Check for tightness by giving it a good shake. If it rattles, replace bearing
  Rudder Should be less than 3/4" deflection at base of rudder
  Keel Look for cracks or signs of looseness, may need to torque keel bolts*
  Align engine  About a week after each launch
     
Misc    
  When needed National Ensign--Replace when it gets discolored or tattered, it must look GREAT at all times
