Clean Burn Engines

[Dangerous]

Dont forget that most of the venues can be quite rough so i doubt if there is gonna be a lot of boat racing anyway!

No one control's the weather ,,,,, not even the RYA!

Clean & Green fleet then is it?

so no old black max 175's with 150 covers etc.

I believe the 175 was a crankshaft rated motor and so put out 150 at the prop. I thought they no longer produced a 175 after they started rating them at the prop as it effectively became the 150.

Can't see a 20yr old Merc holding up against the modern stuff for a whole season.

A well put together 150 merc would be a lot lighter and could potentially be quicker than the modern stuff. 150 mercs come in 2.0, 2.4 and 2.5 configurations too!!!

It would be alot thirstier though so the weight saving could be offset by the extra fuel that would need to be carried.

who stated or questioned any 175 hp motor,as stated before if it has 150 hp on the powerhead/engine cover of any make year mobel it is f3 a 175 is not f3 as it has 175 hp on the cover,this may seem easy to fiddle but if any boat wins to far out in front the engine will be looked at very closley any team or indibvidual breaking this or any other hp (or in other formulas cc) ruling will be dealt with by the racing committee and if found guilty banned its as simple as that,you are just helping the committe look for the cheats or people who like to try and bend the rules!!!

[JamesM]

All I was saying is the old 175 is a 150 when rated the way they rate motors these days. If you were to take a 1981 175 and a 1982 150 they would be the exact same motor except the for the number on the cowl, as 1982 is the year merc started rating their motors at the prop shaft rather than the crankshaft. I don't think there was a 175 blackmax after 1981.

There you go again Bob, It's here mate, the legislation is in place. Move with the times or bail-out.

[OCRDA]

Five more years at least !!

Check the rules !!

[Wacky Racer]

F2 & F3 Classes now rated on horsepower to take into account new engines with higher cc ratings, we are basically following Europe and what they have put in place, Trying to get F3 in Europe to be any 150 hp engine, rules seem to state clean burn only, but it only arrived on the website a couple of months ago. I feel this change has mainly been brought about by Nico and the X class they are running in the Euopean Cup races and Euopean Nationals, This year was the last year for the XR2 in Europe F3, and then they had a separate class for it F3s.

Appologies for delay but struggled to find it .

Anyway the specific OCR engine Ruling as you know is as per the AGM 2002 in Wales which I believe was granted an extention until 2007. (This had no relation to Green Engines) and as yet Green / epa engines have still not been discussed by the OCR committeee or at an AGM .

September 2002

Re: Future class structure of OCR
At last years AGM we discussed the future of OCR classes and engines. It was decided and agreed that we would seek to gradually phase out the 2 litre class and move forward as follows:
1. No new entries would be permitted into the 2 litre class after the end of 2002 and any combination of rig not raced this year would not be permitted to race in 2003.
2. From the beginning of the 2003 season the current 2 litre class will adopt the prefix of X class.
3. A class will be 1850cc 2 stroke or 2200cc 4 stroke with minimum 18 foot, 575kg boats experimental for approx 3 years. Standard production engines will be sealed from new.
4. From the beginning of the 2003 season the current C class (1350cc) will become B class with 1350cc 2 stroke or 1600cc 4 stroke engines, again experimental for approx three years. Minimum weight to remain as is.
I am pleased to report that at yesterdays Offshore Racing Committee (ORC) meeting, the above proposal was accepted. Rule B82 in PB1 states, in paragraph 2, “No changes may be made to the class engine limits (either overall or between sub-divisions) without giving competitors a minimum of six months notice.” The implementation date of these changes is therefore the 5th March 2003.
We also discussed the introduction of a 1000cc “starter” class, to become the new C class, a working paper is underway and will hopefully be ready for the next ORC meeting.

OCR can now move forward knowing where we are going and as important letting others know where we are going. Spread the word , tell people all about it, there is much homework to do on the engines which are available and plenty of opportunity for serious competition between manufacturers. Good luck.


All the best,

Bob Baker


Whilst we no longer Technically come directly under UIM Rules we have always taken guidelines from their rules and as such we agreed with their epa compliance which can be found on the following

If you can't find the minutes of the AGM that first discussed this I am sure I could find it and forward it to you.

If you are still unsure or have further questions please email or call me.
