IBS Náutica - Mecánica náutica y mantenimiento en Port Fòrum

IBS Náutica is a marine mechanical and boat maintenance shop based in Port Fòrum, in the Barcelona area. Its team views the boat as a complete system: the engine, transmission, shafts, propellers, generators, and hull all work together, and a malfunction in one part affects the rest. Their approach is based on a clear principle: diagnosis before any work is performed, with transparent pricing and clear explanations before the boat owner authorizes the work. In addition to the workshop, IBS Náutica sells used boats and assists owners who want to sell their boat.

Why Diagnose Before Repairing

In marine mechanics, it’s tempting to keep replacing parts until the problem goes away, but that drives up the bill and doesn’t always fix the root cause. A preliminary diagnosis—including reading trouble codes, performing compression tests, and inspecting the cooling and fuel systems—reveals what’s wrong, how much it will cost, and what alternatives are available. With this information, the boat owner can make an informed decision.

Preventive Maintenance: What to Check Each Year

Item	Routine Inspection
Engine oil and filters	Every 100–200 hours or annually
Seawater pump impeller	Every 1–2 years
Anodes	At each dry docking
Transmission or saildrive oil	Annually
Saildrive bellows	As specified by the manufacturer, typically every 7 years
Propellers and shaft	At each dry docking

Selling or Buying a Used Boat

As a repair shop, IBS Náutica knows the mechanical condition of the boats that pass through its hands, which gives it an advantage when it comes to appraising a used boat. If you’re selling, a boat with up-to-date and documented maintenance sells faster; if you’re buying, a pre-purchase mechanical inspection prevents surprises.

Signs That the Engine Needs Inspection

• Smoke—white, black, or bluish—when accelerating.
• Temperature higher than normal or an overheating alarm.
• New vibrations, which may come from the propeller, shaft, or mounts.
• Metallic noises in the transmission when shifting into gear.
• Water or oil in the bilge.

Acting quickly often turns a costly breakdown into a simple repair.
