Inboard Engines

Seatech Marine has been servicing, repairing and repowering all types of Inboard Engines for 30 years and has the biggest team of factory trained marine mechanics on the Gold Coast.

As Authorized Dealers for VOLVO PENTA & CATERPILLAR Marine Engines, we have specialised diagnostic equipment to ensure that any hidden problems in your Inboard Engine are detected and rectified in the workshop rather than in the water.

Seatech Marine staff are fully trained to sell, service & repair all MERCRUISER and MERCURY engines. In addition, Seatech technicians are competent at repairing all brands of engines including YANMAR, CUMMINS and DETROIT and our professional Spare Parts Manager can identify and purchase all parts required.

With our FULLY EQUIPPED workshop at The Boat Works, Coomera, we sea trial all vessels to ensure that the repairs have rectified the problems and to ensure that our work is of the highest quality. Seatech has all the specialized tooling necessary to professionally and economically repair your boats power plant.

For your peace of mind, we provide a warranty on all genuine parts fitted by our qualified team.

Why you should service your inboard annually even if you Do Not Use It?

  • Oil becomes acidic after 12 months which leads to corrosion and eventual engine failure
  • Water pump Impellors gain a memory  and will cavitate  after long periods of non usage leading to overheating and engine damage
  • Barnacles attached tothe hull leads to possible osmosis if antifouling is left unattended
  • Lack of battery maintenance could lead to your vessel sinking in the event of a storm if the bilge pump fails to operate
  • Corrosion occurring in the raw water cooling system can lead to salt water leaks over expensive componentry and/or possible submersion of your vessel
  • Water contamination of fuel due to water leaks in the fuel system which can lead to the failure of engine componentry
  • A Total breakdown of your vessel can result in a possibly dangerous situation at sea


At our world class facility at The Boat Works, we can tend to your boat in secure, undercover and fully equipped workshops or in our on-site marina berths. 

We also have fully equipped Mobile Vans working in the Gold Coast region to bring our high level of expertise to your vessel for your convenience. Repairs are carried out at your location with a minimum of fuss and can be organised with our Operations Manager on 55 801 883
