The 840 mm bore is decoded from the RT-flex84t designation — the maker numbers these engines by bore in centimetres.

We do not print figures we cannot source.

About the Wärtsilä RT-flex84t

The RT-flex84t is a two-stroke crosshead marine diesel, 840 mm bore. It is a Sulzer RTA-family design; Wärtsilä acquired Sulzer's diesel business in 1997 and the two-stroke line moved to WinGD in 2015, so the same engine appears under all three names.

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.
