2 or 4 stroke
 

Another thread concerning a 9.9 hp got me wondering what to use to
power a boat I will build. It needs to be up to 75 hp.

Does a 4 stroke really give noticeable increase in mpg?
Are 4 strokes really finicky compared to 2 strokes (I mean reliability).

Duh, where have you been looking? 2 strokes are most certainly
available.

The 4-stroke will give you noticeably better fuel consumption, is a lot
quieter and generally more reliable. The down side is that they are
heavier. That can make a big difference in a dinghy motor but not a lot
when you get above 25HP.

2 strokes ae readily available in models that are a couple years old.
These may be a good deal if still under warranty.

Considering the hassles of how a 4 stroke cannot be tilted some ways,
how reliable are they compared to a 2 stroke?
How expensive to repair compared to a 2 stroke?
Considering a cost differential of about $1000 (US), is fuel economy a
real consideration for a 4 stroke?

Since the gov't got involved, 2 stroke is no longer available, so it is
a no brainer.

Duh Lew, I helped put the government in place and so did you if you
voted. Since private industry will never do the socially responsible
thing unless forced by law, and since most consumers are as dumb as
posts, it takes the government to shall we say, guide the stupid to the
correct answers. In this case, outlawing two-stroke engines. Of course
it could just be that I'm all wrong and allowing 1 out of every 5
gallons of gas passing through my two-stroke to go straight into the
lakes un-combusted is really an okay thing for us to be doing.

I understand the newer 2 strokes are fairly clean.

You want an argument, change the subject.

Ah, those dumb consumers. We surely need a gaggle of wise guvmint
bureaucrats to make all our decisions for us.

How about a gaggle of intelligent, dedicated people who are looking
out for the common good... but that's against your philosophy, right?

The common good... Interestingly, that's a communist philosophy. Or
perhaps, more recently, Al Quaida. Personally, I don't need you, or any
other racial to advocate your preferences on anything.
