What are the current regulations in Cali at the moment? Do new performance boat sales HAVE to include a CARB certified motor regardless the size? I was involved in this a few years back and at the time there were going to be exemptions for say engines over 500hp or so. Is that no longer the case?

Even the multispeed Weismann transmissions will handle the Teague motors. |
I was wondering what was going to happen to the independent builders, if you can understand it here is an interesting EPA doc
http://www.epa.gov/nonroad/marinesi-...8016-chp03.pdf Tyson has done a great job on the 2 speed. As far as single speed transmissions go the VD looks good. We are adding them to our product line. I will have pricing and installation drawings soon. They are a bit longer than the 72 series currently in use, but it is the same unit for both driveline & plug in style which is nice! You either bolt a flange or an adapter plate on the back. |

http://www.epa.gov/nonroad/marinesi-...8016-chp03.pdf What a nightmare. This means one thing for sure- prices are going up. Interesting doc loaded with great info- "Ilmor commented that they estimate that 80% of the High-Performance engines are produced by 5 or possibly 6 manufacturers. (Mercury, llmor, Teague, Sterling, Flagship, Chief). An additional 10-20 very small businesses, produce as little as 15-25 engines per year each." If tohastu thinks they are going to be squeezed imagine the little guys. UD |
I've had a couple of questions via email on how long those transmissions would last at their maximum rating of 2,500 foot-pounds of torque. I am going to try to find an answer.
However, my best guess is ... not very long, just as an engine capable of producing that level of torque likely can't produce it for very long before it fails. But if a product is rated to handle a certain max output, and your highest output is well below that max, the product should last. In other words, I suspect the transmission in question is overbuilt—a good thing in this case—for its intended use. |

Yes, 1500 ft lbs constant. The horsepower depends on the RPM,
HP = 1500 x RPM / 5252 |

The testing is at a state level with the California air resources board - or C.A.R.B.
These guys are nasty strict- to the point that we cant even buy regular fuel cans anymore- they all need big brother caps et all. Uncle Dave |

We tested here at our facility. Marine is a little different than auto.
Cool! Id bet you guy have word class facilities then. How many specs does a carb engine have to meet? UD |
