Generator Service, Repairs and Sales

Seatech Marine has the biggest team of factory trained marine mechanics on the Gold Coast. As Authorized Dealers for KOHLER, ONAN & CATERPILLAR Generators, we have specialised diagnostic equipment to ensure that any hidden problems are detected and rectified in the workshop rather than in the water.

Generators ensure that you have adequate and efficient power for your vessel. As a salt water cooled marine engine, marine generators require the same level of maintenance as your main engines. For your peace of mind, we provide a warranty on all genuine parts fitted by our qualified technicians.


Why Annual Generator Servicing is Important even if you Do Not Use Your Boat?


Generators are often the forgotten child on boats but actually require the same maintenance as the main engines for trouble free power generation. During most services we find that anodes, which are designed to deteriorate before the expensive componentry, are past their use by date and corrosion has already attacked the engine. This can be expensive to repair/replace and preventative maintenance is always your cheapest option.

Generator should be installed by a trained dealer to attract warranty cover and ensure efficient operation and lack of damage to the unit. Incorrect installation has to be rectified by an approved dealer.

Generators require annual maintenance, the same as the main engines for much the same reasons:

  • Oil becomes acidic AFTER 12 months which leads to corrosion and eventual engine failure
  • Impellors gain a memory  and will cavitate after long periods of non usage leading to overheating and engine damage
  • Corrosion occurring in raw water cooling can lead to salt water leaks over expensive componentry and possible submersion of vessel
  • Water contamination of fuel due to water leaks in fuel system and failure of engine componentry
  • Total breakdown of vessel resulting in a possibly dangerous situation at sea
