The base Hino engine is pretty much bulletproof. It is still in production and used in Hino's medium duty trucks and other industrial uses. Marinized it came in 3 versions. Wo4D which is NA and 110 HP, W04C-T which is turbocharged and 150HP except the early 1989 models Bayliner derated to 135HP.
The code which is coming up is P0087 low common rail pressure. Recently Hino has replaced the fuel pump, commonrail and wire harness from the fuel pump to ECU. They also bypassed the fuel lines from the pump to the tank and it still faulted thinking it was a dodgy fuel line.

Weighing my swap I have looked at many engines. Mercedes Atego 4.2, 4.0 mechanical, Isuzu all kinds. Mitsubishi, Nissan and etc. Commuter's engines up to 7 tons especially modern can easily compete with old TLCs engine. Usually ranges from 370ish to 480ish kgs all
