That engine is a BMC 1.5 litre industrial diesel. I dont know who marinised it. The same base engine was popular here in the US and was marketed by Westerbeke as 4.91 and then the Westerbeke 30.

We have been able to get some parts for these from England. Send me a PM if you want.

Looks like an EJ Bowman heat exchanger:

Its definitely a Bowman Heat Exchanger. I've got one on my Mercedes too and looks nearly the same. The BL180 Heat Exchanger fits the British Leland 150 and 180 engines according to some web information. Since it says 15V and 1500 I would imagine it to be the 150 as was said by NCboatrx who seems to know his engines.
kind regards,

G'day,
Correct, it is a BMC engine either a captain or a navigator as the prefix is 15v more likely the latter. They have been marineized by several companys inc british leyland, early times they came fitted with the 'Self changing gears ' gearbox a total horror sprocket box ,hope i never see another one.

The engine is a British Leyland Block 1500cc MARINIZED by BOWMAN -
Bowman still in the business of manufacturing and suppling heat exchangers.

Note: Bowman manufacture heat exchangers and oil coolers and a lot of other heat transfer equipment. They do not marinise engines but they do sell their parts to many other companies in the business of marinising engines.
