About the Wärtsilä 8L46A

The 8L46A is a four-stroke trunk-piston marine diesel in a 8-cylinder in-line build, 460 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 8L46A 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.
