Peter
If you produced a catalogue and a price list it would certainly be hard to prove that they weren't any less of a production engine than something from someone like Ilmor?

There's always some "persons" who will protest these engines if someone fits them for racing right now - unfortunately. So this needs to be discussed at the ORC (RYA), agreed and sorted before going ahead. Frankly I am all for these engines being made available to Joe Public, great idea Pete!

Correct me if I'm wrong, but isn't there something in the rules about a production line of minimum 500 units in order to qualify as "production"? Seem to remember that it states that there must be an "intented" run of 500 units, so why not make 2 and say you intend to make another 498 ?

Looked for that in the rules - where does it mention a minimum production run?

Don't production engines need to be homologated? Surely the rules don't leave "production" undefined?

Marathon engines don't homologation and I haven't found any mention of production numbers, just that they have to be advertised production "Mainstream" production motors - maybe that would scupper Peters plans, does anyone have any more of a definition?

The idea of the smaller classes engine rules, was to make it as affordable as possible and fair...not expensive and elite.

If motors like the D-max were allowed, it would mean ANYONE who wanted to run diesel in D class would have to run these VERY expensive specialist engines to be competitive and std Yanmars would be serious underdogs.. Why is it so hard for some to understand that. Or is it only Goldfish and their agents that think it would be 'fair'. Do you think that would be likely to increase the numbers in D class?

No ones upset, it's just frustrating when no one seems to understand why the rules are as they are, and everyone wants to change them all the the time.

Well said Jon.
We must avoid the "Arms Race" on engines which has destroyed all similar racing over the years.
Remember "P" Production Classes - Mike Lloyd certainly does !
Right from after the 1962 race, when Tramontana 1 had 2308 hp against most others 650 or so max, we have had this sort of thing.
Can't some racers understand the ethos of a "level playing field" ?
With finances for many so tight at present - why try to rock the boat ?

Where vast sums of Money are involved you build to the rules...Because the rules are the rules, as drafted by those who know...
if some "Other Understanding" Was intended then it would have been included within the rules, as those who drafted the said rules are "Experts in their field"
No one is perfect and rules are open to interpretation unless drafted concisely.

Dangerous minefield ground is trodden by those drafting.. best advice is always consult a legal advisor - at least you can sue them if things go wrong....
Sorry Jon if this upsets you but hey.. every penny spent on legal advice is a penny well spent for rule makers, just take a look at Motor Racing ie. F1 - massive advances through interpretation of the rules

Hi SIDEY,
Having had the misfortune to work with diesel engines most of my life i definitely don't want to come home at weekends and play with them. The reason for looking at alternative power units is to try and find something that is very cost effective. A brand new 6.2GM crate engine complete with ECU and serpentine accessory drive is only £6000.00. Being fairly handy with the tools i can marinise them myself and then make my own surface drive which could be used in E Class as a single and in D Class as twins for a lot less money than propriotry engines and drives, i am not wishing to change the rules here.. just saving money and providing me with a great deal of entertainment during the design and build

Peter

Sounds really good Peter - and as we all know Powerboating is never going to be a cheap sport - and even less so with Marathon racing.

But if we can make the entry class, E, more accessable than all the better.

OK, I've dug out the rules.

a) Engines eligible for Marathon classes other than the classes A, B and C (all these are "free") must be based on currently, or previously advertised/available mainstream production units (ie, Mercruiser, Volvo, OMC, Yanmar, Cummins, FPT etc) available to the general public through normal distribution channels with a minimum production run of 500 units. Engines should be from the pleasure line, not the race line of engines from any manufacturer.

If the engine is listed with separate runner exhaust, as described in section (g), the motor is not acceptable. As an example, the Merc 525hp motor used in P1, has CMI headers with runner lengths greater than 6” long, so these motors would not be permissible. The old Merc 500 carb, had GILL/Merc alloy manifolds with common plenum, they would be acceptable, as would STD Merc 496HO‟s, or 502efi‟s.

b) The original bore & stroke must be retained, however, an allowance will be made for OEM piston oversize, i.e., +0.030.

c) Inlet system (intake manifold, intercooler, throttle body etc) MUST remain OEM; throttle bodies must retain OEM internal dimensions


I don't know what mods are made to a D Max - are their exhausts compliant? are they bored out? How about the inlet system? Can someone who knows more tell us?

Apart from that there's some woolly wording in paragraph a. It gives us the figure of 500 units, but what does "based on" mean? What was the thought behind that?

What does "race line" actuall mean? Presumably it had something like Mercury in mind, but does it actually mean anything?

As far as I can see, as the rules currently stand, anyone could take a mainstream production engine and breathe on it within the limits of exhaust, bore/stroke and inlet system and legitimately race it.

Providing they don't specifically market it as a race engine then they could also sell them and they would remain legal to race.
