Professional diagnostics, repair, maintenance, and repowers for boat owners, yacht captains, and marinas throughout the Daytona Beach and Central Florida coastal area. We come to your vessel.
Diesel Engine Service for Serious Boat Owners
If your vessel runs on diesel — whether it's a cruiser, sportfisher, trawler, motoryacht, or commercial workboat — Precision Yacht & Diesel provides mobile diagnostic and repair service at your marina, boatyard, or dock. We work on Cummins, John Deere, MAN, MTU, and other marine diesel engines. Our approach is straightforward: diagnose the actual problem first, explain what we found, and complete only the work that's needed.
When to Call Us
Don't wait until a small problem becomes a breakdown offshore. These are common signs that your diesel engine needs professional attention.

Our Service Process
Every job follows the same documented process — no shortcuts, no guesswork.
Gather Vessel and System Details
We start by collecting your vessel information, engine make and model, current hours, recent service history, and a full description of the symptoms. This helps us arrive prepared.
Inspect and Diagnose the Issue
We perform a systematic inspection using proper diagnostic tools and procedures. We don't guess — we trace the problem to its source before recommending any work.
Explain Findings and Recommended Repairs
We walk you through exactly what we found, what caused it, and what it will take to fix it — in plain language, with a written estimate before any work begins.
Complete Approved Work
We complete only the work you've approved, using quality parts appropriate for marine applications. We keep you informed if anything unexpected comes up mid-job.
