The 3 Marine Blog
Practical marine knowledge from a Keys mechanic who works on these boats every week.
What We Write About
This blog covers four areas where Keys boaters consistently need clear, honest information — not recycled content written by someone who's never held a wrench. Every article comes from real field experience working on boats from Key West to Marathon.
Mobile Service Guides
What to expect from mobile marine service, how to prep your boat for a visit, and when mobile is the right call versus pulling to a yard.
Mercury Repair & Maintenance
Service intervals, common failures by model, CDS diagnostic explainers, and how to get the most out of your Mercury outboard in saltwater conditions.
Marine Electrical
Battery bank sizing, wiring best practices, why shore power corrosion happens, and how to trace electrical faults before they become dangerous.
Keys Boating
Saltwater maintenance specifics for the Florida Keys environment — corrosion, barnacles, skinny water, hurricane prep, and what every Keys boat owner should be doing seasonally.
