Are you sure the head is Aluminium and not just the intake manifold? I always associated the name with manifolds for carb conversions.
Please don't tell me you have a broads cruiser with twin 45 webbers.....  Playful Wink
Ford watermota's were pre crossflow lumps.

If you don't like what I say don't hurl abuse at the boat, I've sold it...

Mangoletsi were /are famous for Manifolds, and very good they are too. To my knowledge they never made cylinder heads, Lucas
( not the electrical firm ) holbay, Cosworth all made aluminium heads for crossfloow Fords. Has it still got 8 valves ? Has it got overhead cam ( s) what carbs ?
You have sparked my interest now, please let us know what you find.
Pictures would help.

Hi All thank you all for your replies. Yes it is deffinatly aluminium head and is 8 valve and its not over head camshaft the rocker shaft has been raised using plates which makes me think the camshaft is high lift.It is 70 bhp and they state 27nots.Tried Mangoletsi I  do not think any body can go back to the 60s and they do not seem to have stored history. What has put me on this mission is a friend said this is a rare engine.Also it was suggested that it could be a Aquaplane Aluminium Head.As I said there are no marks well one mark the number 2 under the rocker cover stamped into head by number 1 cylinder valve springs.It has a Zenith Carb and a Wortham Blake Manifold. Like us all we always want to no a bit more its the challenge.I think this engine set up was on display in the 1966 boat show ?. John

When you get to see this engine if yo look on the right hand side flywheel end of the block the number cast into the block will be 6015
Before this will be the model year eg 711m then the suffix AA/ BA will be the capacity code useful info for tracing parts. The change points were 681m for 1968, 701m for 1971 , 711m for 1971 and 731m an oddball for 1.6 Fiestas.the second 1 in the year code is the code for Kent engines ( 2) was Essex v6 etc

Hi John You could try looking in a Haynes manual for a lotas cortine they somtimes gave a information page. it would have been a cheap way of getting more power in a boat from a small engine that was light.Ford engines were very popular for small boats in the 60's 70's Zenth carb's were fitted to fords before they made there own rubbish Autolight carb,being down draft they were safer in petrol engine boats.Mangoletsy made tuned manifolds that were flow rated and polished in side to remove the air flow resistance,very populer in saloon car racing to get that extra power. the next step would have been to fit a Shorrocks supercharger that ran of the front pully,that would have had to have a S U carb,not so safe in a private boat.John
