Engines, hulls, electrics, emergency call-outs — full-service marine workshop in West Bay. Caymanian-owned and on the same waterfront since 1985, with customer dock access plus mobile service across all three islands.
Most marine workshops in Cayman specialise narrowly — engines OR fibreglass, sales OR service. MDI runs a full-service waterfront facility where the same Caymanian-owned team handles inboard diesels, sterndrives, hull and body work, marine electrics, trailers, and emergency call-outs. Sport fisher, dive boat, motor yacht, sailboat, commercial vessel — we keep Cayman's fleet running.
40+ years on the same waterfront in West Bay. Only authorised Yanmar dealer in the Cayman Islands. All major engine brands serviced. Insurance work, storm damage, routine maintenance, repowers — quoted honestly and turned around quickly so you're back on the water.
