(Obviously the propeller shaft must be locked in position. The engine / gearbox unit has must be centered in the stern tube and running true - to be aligned with the propeller shaft in two ways.
  • Page 12 FLEXIBLE OUTPUT COUPLINGS A flexible coupling is mounted on the gearbox output flange and is strongly recommended in almost every case. Flexible couplings do not resolve bad alignment, they are designed to absorb torsional vibrations from the propeller (transmitted along the propeller shaft).

  • Page 13 EXHAUST SYSTEMS There are two main types of exhaust system: We recommend care when designing your exhaust system. The most important aspect is to ensure that water 1) Standard yacht - wet exhaust system with a water cannot enter the engine’s combustion chamber from the injection bend and waterlock silencer exhaust system (this applies to both wet and dry exhaust 2) Dry exhaust system (see page 17)
  • Page 14 HIGH-RISE EXHAUST In yachts, engines are mostly installed low down and standard injection bend is too low then we can offer a often below the water line. There are several ways to high-rise injection bend that adds 15 cms to the height. avoid cooling water entering the engine.
  • Page 15 WATERLOCK / SILENCER You must always fit a waterlock / silencer to stop any injection bend, being as low as reasonably possible, so water in the exhaust system back filling the engine. The that all the water can drain down into it. The waterlock water lock should always be fitted at least 30 cms away should have sufficient capacity to hold an exhaust system from the injection bend and at least 30 cms below the...

As the emission regulations are steadily introduced and tightened we/Kubota are now left with no alternative but to introduce our larger engines with turbochargers - in the power brackets 37kW to 56kW, and 56kW to 75kW.

  • Page 47: Troubleshooting

    Trouble Shooting Beta diesels are very reliable if installed and serviced correctly, but problems can occur and the following list gives the most common ones and their solution. Problem: Engine does not start but starter motor turns over OK Possible Cause Solution No fuel: Turn fuel cock on and fill tank.
  • Page 48 Problem: Low power output Possible Cause Solution Propeller is too big: Change or depitch. Check gearbox reduction ratio relative to propeller size: Change. Blocked fuel filter: Replace. Blocked air filter: Replace. Air in fuel system: Check system and bleed Governor spring incorrectly mounted: Dealer to adjust.
  • Page 49 Problem: White or blue exhaust gas Possible Cause Solution Engine oil level too high: Reduce the level. Blocked injector: Service injectors. Piston ring and bore worn or con rod bent due to water Get compression checked by your dealer or Kubota ingression, giving a low compression: service agent.
  • Page 50 Problem: Water in lubricating oil - heat exchanger cooled Possible Cause Solution Oil goes “milky” due to seawater entering exhaust manifold: Check installation - has anti-syphon valve been fitted? Change engine oil and run engine for 10 minutes each time to eliminate any water. Get fuel injection pump and compression checked by Service Agent.
  • Page 51 Problem: Engine overheats - Keel cooling only Sometimes overheating is caused by: (a) Not fully venting the engine cooling system of air. It is necessary to remove all air from the cooling system - including the “skin” tanks and (if fitted) the Calorifier and associated piping. (b) Incorrectly sized “skin”...
  • Page 52 Problem: Vibrations Possible Cause Solution Poor alignment to shaft: The alignment must be accurate even if a flexible coupling is used (see section 1, Alignment). Flexible mounts not adjusted correctly to take even weight: Check relative compression of each mount. Flexible mount rubber perished: Replace.
