Our Marine Engineering Services

serving the south west & devon

At Darthaven Marina, our Marine Engineering Services team delivers expert care, precision workmanship, and trusted support for every aspect of your vessel’s mechanical and electronic systems performance. Whether it’s planned maintenance, technical diagnostics, breakdowns, or full repower projects, our engineers ensure your boat operates smoothly and reliably season after season. Our fully qualified, in-house engineering team offer responsive solutions, technical excellence and a commitment to safety and quality at every stage.

Servicing
Reliable performance starts with consistent care.
Our marine servicing covers everything from basic engine oil changes to full manufacturer-scheduled maintenance. We follow OEM specifications, use genuine parts, offer oil sample routines and provide service logs for your records – ensuring your vessel runs smoothly, safely, and efficiently all year round.
Repairs
From minor faults to major rebuilds, we’ve got you covered.
Our engineers diagnose and carry out mechanical repairs across a wide range of engine, propulsion and vessel systems. Whether you’re dealing with noise, vibration, or visible wear, we’ll restore your systems to full working order with precision and care.
Diagnostics
Smart fault-finding that gets to the root of the issue.
Using advanced diagnostic tools and years of hands-on expertise, we’ll quickly identify any performance concerns or warning alerts. Whether it’s a fault code, intermittent issue or drop in efficiency, our engineers will investigate, report, and recommend your best next step.
Repowers & Installations
Upgrade your vessel with confidence and care.
Thinking about replacing your engine, adding a generator or upgrading key systems? We design and deliver complete repower solutions - including alignment, fuel systems, mounts and cooling - tailored to your requirements.
Winterisation
Protect your engine through the colder months
Our comprehensive winterisation packages help prevent freezing, corrosion and costly damage. We’ll flush, stabilise, drain and secure your mechanical and domestic systems - then recommission them in spring so you’re ready to launch without worry.
Mechanical Inspection
Have peace of mind before you buy.
Buying a boat or travelling further afield? We offer independent, mechanical inspections that assess the engine, gearbox, fuel systems and more. You’ll receive a detailed engineer’s report to inform you of the condition of your systems.

A lovely picturesque spot. Staff were very helpful and welcoming. Facilities were well managed and clean. Looking forward to coming back.

Really friendly team and a well stocked chandlery; they found space for us when they were full this summer when we needed to hide from the storms and make repairs. Pretty location and easy access to Dartmouth by the great ferry. Will definitely be back.
