Yanmar
Authorised Dealer — Cayman Islands

New Boat Engines
For Cayman's
Waters

Marine Diesel & Industrial is the only authorised Yanmar dealer in the Cayman Islands. New marine engines, re-power packages, and genuine parts — fully installed by factory-trained technicians.

Built to Perform.
Built to Last.

Yanmar manufactures marine engines for pleasure and commercial use — designed for high performance and maximum engine life. Tested under extreme conditions, they've earned a reputation for legendary reliability in some of the world's most demanding marine environments.

Common Rail Direct Injection (CRDI)

Yanmar's CRDI system stores fuel at over 2,000 bar in a shared rail, injecting precise micro-bursts electronically at any RPM — more complete combustion, more power, lower emissions than petrol equivalents.

30–40% Better Fuel Economy

A properly-specified Yanmar diesel inboard typically consumes 30–40% less fuel than a petrol engine of equivalent output. At Cayman fuel prices, that's real money every season.

Compact, High Power-to-Weight

Yanmar's inline-4 and inline-6 configurations pack serious horsepower into a compact footprint — less weight on the stern, more room in the engine bay, better trim.

Genuine OEM Parts — In Stock

As the only authorised Yanmar dealer in Cayman, MDI carries local parts inventory. No weeks waiting for imports — common maintenance items are on the shelf, ready to go.

Full Factory Warranty

Every new Yanmar purchased through MDI carries complete factory warranty coverage, serviced locally by our trained technicians. No shipping your boat off-island for warranty work.

Only Yanmar Dealer in Cayman

MDI is the only authorised Yanmar dealer in the Cayman Islands. Most other marine brands have no authorised local dealer — meaning warranty work and genuine parts depend on costly imports. With Yanmar and MDI, factory support is on island.

Yanmar vs The Field

Every engine brand has its place. Here's an honest comparison of Yanmar against the alternatives most commonly considered in the Cayman Islands — and why Yanmar is our primary recommendation for most vessels.

Our Verdict ✓ Primary recommendation Capable engines — no local backup when it counts High running cost — consider diesel Right tool for large applications

Not Just Yanmar.

Yanmar is our primary recommendation — but we work with all makes. If your project calls for a different engine, we can source, supply, and install it.

MAN Marine
High-Performance & Commercial

MAN marine diesels are built for serious applications — large sport fishers, commercial vessels, and high-performance builds where 400hp+ is the starting point. We supply and install MAN engines across the Cayman Islands.

Yanmar Diesel Outboards
Commercial · Charter · High-Hours Operators

As Cayman's only authorised Yanmar dealer, we supply Yanmar diesel outboards for commercial and high-usage applications — lower fuel burn, longer service life, and genuine OEM parts on-island.

Drives & Transmissions
Saildrive · Sterndrive · Shaft Drive

Complete marine transmission and drive systems — saildrive, sterndrive, and shaft configurations — supplied and installed for new builds, re-powers, and upgrades across all vessel types.

What Operators
Are Saying.

"Since installing these motors I have put about 400 hours on them — roughly one fishing season. During this season I had no issues with these motors, they performed flawlessly and efficiently. I noticed major fuel gains and the boat performed much better with weight on it. The boat now cruises at 27 to 31 knots in deep water at 3,400 rpm. My overall experience with these motors has been excellent."
