The Thornycroft 230 is a 4 cylinder, 4 stroke, vertical, inline 3.77L diesel engine, based on the Leyland 4/98 Bathgate engine.

Most 230 engines were marinised in heat exchanger cooled configuration, and found an appreciative customer base among the river and inland waterways trip boats and larger pleasure craft. The engine was also produced as the 230R, using new marinisation on a factory reconditioned base engine, and painted bright metallic green.

Thornycroft never marinised the earlier BMC3.4 and BMC3.8 engines. Those were the forerunners to the Type 230. Many parts are interchangeable, but certainly not all.

The 230 engine has wet liners. The engine cooling circuit must be treated with a good quality inhibitor to ensure maximum liner life. Include inhibitor checks as part of your regular maintenance schedule.

From the MS-05-230 Thornycroft 230 leaflet, ratings are as follows:
