Looks a bit like a ford V4 (transit van etc)

I should mention it has a Chrysler Marine tag on the bellhousing.

Well, you have probably worked out that it is a marinised Chrysler V8. Popular in the 60's and 70's, maybe even later. For example Riva used them. The logo on the header might give a clue as to who marinised it, but suspect if it has Chrysler Marine on the bell housing it could be a factory product.

gosh, what a clean and tidy engine !

Are you looking to buy the boat or ....?

New hoses and alternator as well as resprayed. Just the one by-pass hose with overspray on (shame). Someone has spent a bit of time and money on it. Quite recently by the look of it.

Further research makes me believe it is a Chrysler "LA" engine either 273 or 318, late 60s early 70s. Casting number gave a clue.

It certainly looks in fine fettle.
What size of Lyman is this beast lurking in?
I have a Lyman catalogue from 1968, and they had lovely timber cruisers then in a range 16', 18', 19' and 22' (and bigger).
It is quite possible that they were still building your model 10 years later.

So I have found it is a Chrysler 273 with a Velvet drive.

More numbers on the Chrysler Marine ID plate on the bellhousing.

M273-BWR10-288

Serial # - E066754

12-16-P

It is a 1958 23' Lyman with a newer motor.

So I am trying to determine the exact year of the engine. Late 60s-early 70s.

Does anyone know exactly what year it is based on the serial number?

Thanks very much.
