Did you consider that a four stroke may be passing a quantity of oil into the exhaust too? That would be fairly common. If there is absolutely no tolerance then you better just ban all engines on boats and get used to fish and chips hold the fish.Quote:

We are all polluters, every one of us, its a case of making an effort, which is why I spent $14,000 on a high tech outboard motor, instead of persisting with the "old" 2 stroke.
Of course, you were not floating, were you?Quote:

A Qld. Main Roads engineer tells me that the standard for Main Roads Dept. works now is maximum 10% grade.He says in Qld, Cunningham's Gap, Toowoomba Range, and a section of the Gillies are all on the 10% limit for short sections with around 100 metres of the Gillies still at 12%, it being deemed not of economic benefit to reduce this. I read this as being "will cost too much".

Lets make it simple..... go back & read the two strokes pollute water bit with my first post. I dont give a **** about boat engines be they 2 or 4 stroke, the comment was made that "2 strokes pollute the water" Mr. Whippy didn't understand how they could pollute & I explained. As you stated, yes the injected 2 stroke is WAY better & yes the 4 stroke could be dumping a bit of oil as well but that isn't what it was about.
