Mercruiser oils and spare parts
Mercruiser oils, anodes and service kits.

In the Mercruiser oils and spare parts section you will find original Quicksilver branded maintenance products for Mercruiser inboard engines and stern drives – Mercruiser differs from Mercury outboard engines in that it is an inboard or stern drive engine, whose maintenance needs (engine oils, coolants, oil filters, anodes, impellers and service kits) differ from outboard engine maintenance. The range includes, among others, Quicksilver Mercruiser engine oil 25W-40 (in 1 and 4 liter packages) and Mercruiser glycol 50/50 for the cooling system.
The cooling system of an inboard engine often includes both a seawater circuit and a closed glycol circuit, so maintaining the correct glycol to water ratio is important for frost resistance and corrosion protection. Anodes protect metal parts against galvanic corrosion in seawater and wear out with use - it is worth checking their condition regularly and replacing them before they are worn out, as a worn anode no longer protects other metal parts.
