The 500 mm bore is decoded from the ZA50S designation — the maker numbers these engines by bore in centimetres. Stroke and output for this exact build are not published in any source we hold, so this page does not state them. Send us your engine and part number and we will confirm against the plate. We do not print figures we cannot source.

About the Sulzer ZA50S

The ZA50S is a four-stroke trunk-piston marine diesel, 500 mm bore.

We publish only what we can source. Where a maker figure is not in our records, this page says so rather than estimating it — a wrong tolerance on a spare-parts page is worse than no figure.

Why Source ZA50S Parts from Wattmare?

We are in Bhavnagar, next to Alang — the world’s largest ship-recycling yard, and where reconditioned main-engine parts actually come from. We hold fast movers, source the rest through the yard and our trader network, and dispatch worldwide in 24–48 hours on emergency orders.
