Marine Maintenance & Repair Guides
Practical guides for the systems boat owners are expected to maintain themselves. Electrical, anodes, engines, hull systems. ABYC and manufacturer documentation cited inline where applicable.
Available guides
Corrosion & anodes
- Marine Zinc Anode Replacement: When & How
Anode chemistry by water type (zinc/aluminum/magnesium), location map for typical boats, replacement procedure, current 2026 pricing.
Engine maintenance
- Outboard Motor Winterization Procedure
Fuel stabilization, cylinder fogging, lower unit oil change, freshwater flush. Two-hour procedure that prevents $1000s in storage damage.
Coming soon (Q3 2026)
Planned guides: raw-water cooling system flush, lower-unit oil change procedure (in-depth), battery bank sizing for cruisers, shore-power galvanic isolator testing, bottom paint selection by hull material, through-hull inspection schedule, and bilge pump sizing. Each guide is researched against ABYC standards and manufacturer service documentation.
How FixForge marine coverage is organized
Marine systems break down differently than residential or automotive systems — saltwater, constant moisture, dissimilar metals in contact, and 12V-to-120V transitions create failure modes that don't exist on land. Our marine guides assume a typical recreational boat (outboard center console, inboard cruiser, trailerable sailboat, or small powerboat) in mixed-use conditions. Where guidance differs for full-time liveaboards, commercial vessels, or specialized hulls, we say so explicitly.
Where we cite ABYC standards (the American Boat & Yacht Council's electrical, plumbing, and rigging guidelines), we reference the specific standard number so you can verify directly. Manufacturer service procedures override generic guidance where they apply — if your engine manual says do X, do X.
Pricing reflects 2026 marine market
Marine part pricing has historically been a significant premium over equivalent automotive or residential parts, and that premium has grown in 2024-2026 due to supply chain shifts. Our cost ranges reflect current marine-channel prices (West Marine, Defender, Boatzincs, manufacturer-authorized dealers) rather than generic equivalent pricing. We update guides when prices move more than 15% from the cited range.
