UIM 3C EPA/Carb. Engine rules

Hi all. Next week it is 3C World Championship. I'm looking for answers on some issues regarding the rules.

1: 2010 Mercury 200xs does not have EPA/carb rating even thought UIM rules requires that. How should this be judged?

2: adding material to exhaust in midsection. According to rules you may add material to lower noise but exhaust plate must be in place. How about removing the plate and add a exhaust silencer?

Hi Jonp.. The matter of the exhaust has been taken up before and was adjudged to be illegal as it allows the engine to breathe more easily . By removing the exhaust plate and adding a silencer it gives the exhaust gasses another exit route. Some Scandinavian teams did run them on the XR2's and the way they were gasflowed internally did allow the gases to exit easier from the leg, but they were allowed to run them as they did in fact make the engine slightly quieter as the plate had 10 x holes in the latter ones and 1 large one on earlier models. The XS plate has none... Hope this helps.

Exactly. But my question is if it is ok to remove the plate and put a silencer instead? I find it to be against the rules. To keep the plate and add the silencer should be OK though. But there comes another issue and that is if the engine now complies with EPA/Carb classification? It should not since the engine is only classified as is from factory. And as a follow up on that how about the 2010 Merc 200xs that is not EPA/CARB classified. Seems to me that that engine does not comply with the rules at all since the rules state only EPA/CARB is allowed. Please help me clear this out.

I see. There is nothing that shows that it is not compliant to EPA/CARB but it has not been classified and therefore I was looking for answers as to if the 2010 Merc 200XS actually is legal in 3C?

Regarding the exhaust issue.... well doesn't anyone read the rules anymore?

Hello Bob. I received your voice mail this morning. Sorry for my delay in responding to your question. The 2nd generation of the OptiMax 200XS ROS outboard is a race engine - sold without warranty - and thus we didn't apply for EPA/CARB emissions regulations. The previous version of the engine - (Gen1), which had been sold as a consumer - recreational engine - was certified as a 2-star CARB/EPA emissions compliant engine.

I hear that the 2010 XS is badged as a 225hp engine!

Now that sounds pretty strange for a 200hp class.......

There is a lot that's strange with the 2010 200xs and 3C. For example that the engine is not EPA/CARB/EU certified but the rules state that it should be. To bad since the engine is such a gem. Another example is that 2010 200xs is sold as a non warranty racing engine (stated in the e-mail enclosed above by OCRDA) but the rule clearly state that it has to be a consumer engine manufactured in no less that 250 units.

The 2010 200xs SST (the circuit racing version) will be rebadged to 200 hp by just changing the badge on existing engines according to rumours in Sweden.

According to another rumour UIM and Mercury are negotiating on how to solve this issue.

This email was sent to JP and many others in authority. Photo is to big to attach...sorry


Hi John



Here as promised is the photo of the engine plate for the 2010 version of the Mercury 200XS. The photo is good enough quality to be able to zoom in on the relevant portion. All class 3c boats with the exception of us and one other were running this engine in Corsica. The rules clearly state that engines must be…under 3000cc, EPA compliant and 200hp, the Mercury 200XS 2010 model only passes one of these criteria. We do not wish to make problems with respect to this year’s event, as it was superb for all who attended and after our crew injury on the Friday we were completely out of the running anyway. However the rules need to be clarified for future races and events.



Cheers Paul

From the UIM

6. Regarding the Mercury 200XS as used in the 2010 Worlds the UIM confirmed the following: This engine was not EPA or CARP approved however Mercury have advised the UIM that this engine meets all current CARB and EPA emissions, a letter from Mercury to this effect has been lodged with the UIM. The concerns raised regarding some of these engines having Mercury plates stating that they were 225 hp engines was also explained by Mercury. Mercury stated that a small number of 200 XS powerheads had been fitted to mid sections which are also used for 225hp units. Mercury apologised for the confusion and assured Cominoff that this would not be repeated. This was accepted in good faith by Cominoff delegates.

Great that problems been solved eventhough I feel it leaves av slightly bad taste in the mouth. Mainly because part of it is untrue. Merc does not produce any motors with 225 hp with the 15 inch mid section.

The statement from Mercury is so ridiculous its untrue, how can a governing body be so inept to take this statement at face value without doing any simple research itself. I cannot see the FIA accepting this type proof from an auto racing manufacturer.

All 2010 200XS in Corsica (at least 25 units including spare engines) had the same saddle sticker, stating that the HP was 225. The very same sticker has 200xs above the HP rating. Surly if the Mercury statement was true, some of the engines in Corsica would have a 200hp rating, and surly if the engine had been placed on a differnet models mid section, the model would not have said 200xs above the HP rating.

What happens if Evinrude send a letter stating that their 250 HO is really a 200, but was misbadged due to a factory error, would that mean UIM would accept this engine also........I think not!!!!
