Lifeboat Diesels

On the Patriot State there are three diesel lifeboats. Boats 1 and 2 forward of the house contain Buka diesels. Each Buka diesel powers a 145 man lifeboat and has fuel capacity for 24 hours of continuous operation. Boat 5, at the sun deck level on the starboard side aft of the house contains a Westerbeke diesel. The Westerbeke diesel drives the lifeboat which holds 74 persons for 24 hours.

Start-up Life Boats Number 1 and 2 (Buka Diesel)

  1. Inspect dipstick for the oil sump and transmission.
  2. Check the fresh water level in the expansion tank.
  3. Look the engine over for any loose gear or unfinished work.
  4. Inspect drive belts for looseness.
  5. Make sure cable pull for the stop is pushed in.
  6. Pull the throttle cable all the way out.
  7. Place shift lever in neutral position.
  8. Fuel valve under seat should always be left open.
  9. Seacock water valve should always be left open.
  10. Place compression relief valve on valve cover down, this holds open the exhaust valves.
  11. Place hand crank into the drive attachment, crank by hand. When turning as fast as possible helper will flip compression relief lever back, engine should start.Good luck.
  12. As engine starts push in throttle cable to prevent over reving.
  13. Check oil pressure when engine starts, it should rise within 20 seconds, if not shut down.
  14. Engine temperature should rise and not exceed 185° F, if it does slow down. If it continues to rise shut down.
  15. Check the oil pressure and water temp every few minutes. Carefully examine the engine while it is operating looking for leaks and loose parts.

Start-up Boat Number 5 (Westerbeke Diesel)

  1. Inspect dipstick for the oil sump and transmission.
  2. Check the fresh water level in the expansion tank.
  3. Look the engine over for any loose gear or unfinished work.
  4. Inspect drive belts for looseness.
  5. Make sure cable pull for the stop is pushed in.
  6. Pull the throttle cable all the way out.
  7. Place shift lever in neutral position.
  8. Open valves for hydraulic start accumulators, pressure should be near 3000 psi, if not, hand pump up.
  9. Fuel valve under seat should always be left open.
  10. Seacock water valve should always be left open.
  11. Firmly push in start control valve on the outside of the housing, engine should start.
  12. As engine starts push in throttle cable to prevent over reving.
  13. Check oil pressure when engine starts, it should rise within 20 seconds, if not shut down.
  14. Engine temperature should rise and not exceed 185° F, if it does slow down. If it continues to rise shut down.
