What engine is this?

Hello, all....

Not a truck question, although it is a Ford diesel. I just bought a restoration project - an old 54' motor launch converted to a motor yacht at some time. It has a Ford straight-6 diesel in it, but I can't see a model plate or a labl on it. I'm going to crawl down into the engine space tomorrow for a better look, but until then, can any diesel fanatic just look at the "from above" pic and recognize what sort of engine it is?



Thanks if anyone can help.

Richard

Looks like a Ford Lehman engine to me, from here. I have seen a few, sure not an expert. If I remember right, had a American Bosch FI pump, and were a very simple, basic engine.

IF I remember right, the older inline four was called a "90", and the in-line six was a "120". This referred to the horsepower. Just a wild guess from an old guy....

The Lehman 6's comes in various Cubic Inches and HP ratings, They also come N/A and Turboed, it's been a long time since I've seen or even heard of them!

They used to be very popular generator and pump motors, never seen one in a Marine application.

Thanks, everyone.

The word "Lehman" and some googling found an online copy of the owners manual for Ford Lehman marine diesels, from which I was able to determine that the engine's an SP-135, which is the normally aspirated version, sold from 1982 onwards. It also showed me where the data plate should be. Maybe tomorrow I'll find a year and serial number.
