Tecnoseal Yamaha Outboard Anode Kit 300–350 HP

Tecnoseal Yamaha Outboard Anode Kit 300–350 HP – Zinc, Aluminium or Magnesium

The Tecnoseal KITYAMAHA300-350 series consists of sacrificial anode kits designed for Yamaha 300–350 HP outboard motors. Each kit contains two replacement anodes manufactured from the same sacrificial material, providing corrosion protection for compatible Yamaha outboard components. Mounting hardware is not included.

Each kit includes one Tecnoseal 01112-1 series anode and one Tecnoseal 01155 series lower unit anode. These components help protect metallic outboard parts against galvanic corrosion by acting as sacrificial anodes that corrode preferentially during service.

Three versions are available: zinc (Tecnoseal KITYAMAHA300-350), aluminium (Tecnoseal KITYAMAHA300-350-AL, Osculati 43.355.14) and magnesium (Tecnoseal KITYAMAHA300-350-MG, Osculati 43.355.15). According to the Tecnoseal catalogue, the zinc kit weighs 1.95 kg (4.30 lbs), the aluminium kit weighs 0.84 kg (1.85 lbs) and the magnesium kit weighs 0.60 kg (1.32 lbs).

Compatibility Note: Before ordering, verify the Yamaha outboard model and individual anode part numbers included in the kit.
