ford 1600 petrols.

[aztec]

hi, i have bought a boat with a pair of ford 1600cc petrol engines (watamota?) both run ok, but i need to replace them with 1800 diesels.

Q1) are the old petrols worth anything?
Q2) would i be better off with 1600 or 1800 diesels, or even 1800 turbos?

has anyone any experience with these type of engines in a 26ft boat with deep V hull, advice on this aprecuiated before i commit myself. (or my wife has me committed!)

cheers steve.

I would doubt if your drives (Enfields?) would last long with 1600 diesels,let alone 1800tdi
The torque is far more than 1600ohv could ever produce.

 

[aztec]

Mmm, i can see your point may have to rethink this one!

cheers.

Enfield legs are good for about 120 hp i think

 

[aztec]

ok rethink done! HELP

i need to know the relative hp figures of these different engines me thinks?

 

[kimhollamby]

Thing to watch out for is torque, not horsepower. Diesels are more 'torquey' and, therefore, put a greater strain on gearing.

That said, fairly sure there are plenty of Enfields married up to Perkins 4.107/8 and the like, admittedly smaller than your intended diesels but perhaps not so far off given that the torque from a high-revving 1600cc modern diesel will be further up the graph.

Talk to Bob Knowles Plant Hire (Enfield agents) and Lancing Marine; contact details for both on the ybw directory (see bottom nav link).

Whatever you wind up with, Enfields are not going to get your boat going very quickly, so don't over-engine.

thanks kim, i think that the original engines could have been 4.108's but due to the ease of fitting the ford block this is the way i want to go.

but, why won't it go very fast with enfields? can gearing not be changed and can props be changed to suit?

Just another thought,what about an 1800cvh siera petrol engine.More power and speed,not so thirsty,and kinder to drives.I think (but not certain)the bolt patterns are the same.

 

[Jcorstorphine]

Why not think about converting to LPG and keep your present engines,cost for fuel is a great deal less.

As Kim said, if you overtorque the drives by fitting 1800D you will wreck the legs. As I said in a previous posting to you on Classic, you could also talk to Watermota about their Cortina 1600 Diesel which devloped about 35 HP at 3000 RPM.

Yes the CHV does share the same bolt pattern, and has engine mounts in the equivilent, position (providing it came from a sierra) but, i want to use diesel as a cost saving over petrol.

i think that the initial cost of fitting LPG, would prove to be prohibitive and therefore not an option at this stage.

Does anyone make or operate a marinised version of the 1800 CVH engine?

 

[Col]

Try the companies listed in this thread.The reason you will get no speed with Perkins is,they are limited (governed) on max rpm to something like 2,800rpm.If you fitted a longer pitch prop to compensate you are making the torque problem worse(imagine trying to pull away in third,inyour car)but whereas in your car the clutch would suffer,in your boat, its the drives.Couple that with a torquier engine=recipe for disaster.

Steve, Lancing Marine really are the Canine's Testicles when it comes to the sort of thing you want, have a word with them.

cheers col, that makes sense, i was'nt aware of the govenor on perkins being so low. i'm used to high speed car type engines.

 

[aztec]

the truth is out there

took Byrons advice again, contacted Lancing marine, awaiting info which could decide the fate of the boat. thanks to all who (whom?) replied. i'll post result from lancing as i hope this thread could help others.
