Tecnoseal Yamaha Outboard Anode Kit 300–350 HP Extended Protection

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

The Tecnoseal KITYAMAHA300-350XP series consists of extended protection sacrificial anode kits designed for Yamaha 300–350 HP outboard motors. Each kit contains three 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, one Tecnoseal 01155 lower unit anode and one Tecnoseal 01169 gear case cap anode. These components help protect metallic outboard parts against galvanic corrosion by acting as sacrificial anodes that corrode preferentially during service.

Compared with the standard Tecnoseal Yamaha 300–350 HP anode kit, the extended protection version includes an additional Tecnoseal 01169 gear case cap anode. This increases the number of sacrificial anodes from two to three, providing an additional corrosion protection component for the gear case.

Three material versions are available: zinc (Tecnoseal KITYAMAHA300-350XP), aluminium (Tecnoseal KITYAMAHA300-350XPAL) and magnesium (Tecnoseal KITYAMAHA300-350XPMG). According to the Tecnoseal catalogue, the zinc kit weighs 2.25 kg (4.96 lbs), the aluminium kit weighs 0.96 kg (2.12 lbs) and the magnesium kit weighs 0.68 kg (1.50 lbs).

Compatibility Note: Before ordering, verify the Yamaha outboard model and individual anode part numbers included in the kit. The stated 300–350 HP range does not establish compatibility with every Yamaha outboard within that range. Select the appropriate sacrificial anode material according to Yamaha's recommendations and operating water conditions. Mounting hardware is not included and must be supplied separately if required.
