Default Catalytic converters
The link above has a article on what the future appears to hold for gasoline powerboats in 2010.
What struck me immediatly is the width of the engine with converter. It looks like a twin engine application would not fit into a 8 foot hull !
Plus the plus 15K price increase per engine from Mercruiser.

I was at Mercury Service School last week for Catalyst Products. (they have been shipping them to California boats all year) It's not too bad only fractions of an inch wider on 496's. It is still work in progress. 500HP and up are currently exempt as the EPA looks at the whole line.

Inside the converter, stainless steel mesh holds the catalysts in place, according to Indmar, even during rough conditions. The interior has also been designed to be easily serviceable; remove an O-shape snap ring and you can replace the interior components.
I like this part.... I'm sure the cost of these suckers are astronomical if they fail and needed replacing. A servicable unit will keep the cost down a little. Could it be that someone is looking out for the owners wallet?
