(b) Hyundai Seasall U140 Diesel Engine



1.7 Liter Compact High Speed Diesel

The new U-engine family brings to boating the additional benefits of diesel
power which, in the past, were limited to use gasoline engines.
It features a compact package which combines sophisticated common
rail electronic fuel injection (CRDi) with the latest generation computer
controlled engine management system.
A variable geometry turbocharger (VGT) coupled with the intercooler
provides superb acceleration as well as optimal boost at cruise – all while
keeping fuel consumption under tight control. Available for inboard, sterndrive
and jet applications, whether the need is for new builds or for repower, the
U140 is ready to serve.
