Marine Engine Services
Regular engine maintenance is essential to ensuring your engine will provide you with years of trouble-free operation. At Onshore Marine we have the expertise and training to handle all of your engine maintenance service and needs.
Marine engines can often be used for extended periods at wide open throttle (up to 6000rpm on some models) in harsh salt water and sun, then sit in storage over winter for up to 6 or 7 months without any use.
Sometimes, infrequent use may not alert you to minor maintenance requirements that could eventually lead to starting or reliability problems right in the middle of your valuable recreational boating time.
Problems like a minor oil leak or fuel system contamination can lead to expensive repairs if not attended to in a timely manner. That’s why it’s important to have your engine inspected and serviced at an authorised dealer at least once a year – even if you haven’t reached 100 hours. It does not mean that the normal service and maintenance items are only designed to last 12 months, it means that we can attend to any tune-up, service or warranty issues to ensure you get maximum pleasure and carefree running out of your engine.
Based on the Northern Gold Coast (QLD), we offer water testing, on water engine services and can cover all routine maintenance tasks with genuine parts and services consumables.
