Volvo Penta have now Launched Boat Engines With Catalytic Converters

August 2008 The first gasoline engines, fitted with a catalytic converter for leisure boats, have arrived. ther will be four sterndrive models and one IPS, they will all meet the Requirements ot the Califiornia air research Board (CARB)
The catalytic converter components are fully integrated into the aluminium exhaust system.
and they will be equipped with advanced electronic engine control systems, comprising -
Electronic multiport fuel injection with two oxygen sensors, before and after the catalytic converter, enabling the optimum combustion process
The fuel system also includes emission monitoring and diagnostics to alert the driver if the exhaust emission control is not functioning correctly

These engines also have double walled exhaust systems with cooling water flowing between them,this keeps the outside of the exhaust cool while allowing the catalytic converter to run at the correct temperature.
These engines will be rated from 150 hp (4 cyl) thro’ 270 and 300 hp (small block) to 400hp (big block) they will be low weight and low corrosion due to the advanced and Titanium coated aluminium alloy exhaust materials used which is a first in marrine applications.

Quote: Volvo Penta is offering an uninterrupted supply of its 8.1L big-block power for all of 2010. Despite plans by General Motors to stop production of its 8.1L engine blocks, Volvo Penta has worked with GM to ensure its ability to supply customers with the popular 8.1L engines for sterndrive and IPS propulsion systems

Good to hear they will still be available for those of you looking at new units but did I not hear or read somewhere that all marine engines require catalytic converters and that new boats will be going up by apprximately 5-10K for these changes?

How would that work? Automotive catalytic conveter normal operating temperatures can range up to 1,200 to 1,600 degrees F. This would have to be upsteam of introducing water into the exhaust. That would be a lot of heat in the engine compartment.

Well live and learn. Leave it to California to force another change that impacts the whole world and costs us all money. I'd hate to have to replace one of those.

I can't help thinking that emissions/ fuel consumption/ health of your wallet/ global warming/ global cooling / climate change whatever you prefer would be positively affected, certainly in a reasonably low weight boat, if you had 250kg Al engine(s) rather than a 5-600 kg lumps of cast iron as engines!

Cap'n..... Any idea on cost impacts? This may help the used boat market come spring time.
