[Rhodes22-list] Engine Discussion

[Kroposki]

Bill,
	Last year (or before) we had a similar debate whether electric
engines would be the way to go.  Last week there was a race of solar
powered cars in Japan.  They were racing at 45 mph without smoke or
noise.  Maybe we can get Roger to design a main sail that is also a
solar collector.  Now that would  be a main sail that even Stan might
want considering he is alleged to use a trolling motor to dock.

Well,

Not necessarily.

Did you see the letter in the latest Practical Sailor about the guy with
the 2 hp Honda 4-stroke that was such a lemon Honda gave him a new
engine after more than a year of total unreliability? 

As a group, small 4-stroke engines are not as reliable as 2-strokes.  At
least not now.  Maybe never.

All of the testing cited by Roger and Michael is for much larger engines
than the ones we use on our boats--and the engines are run nearly full
throttle--something we almost never do.  

Manufacturers have already demonstrated that they can develop 2-strokes
that meet the emissions requirements in the size engines they put into
PWC.

Take a look at this beauty from your friends at emissions concerned
Yamaha:

Please note that even Yamaha cites the reliability of 2-strokes over
equivalent 4-strokes.

Small 4-stroke carburated engines like the ones we use on our boats do
not meet the cited specifications for fuel efficiency in the way we use
our boats.  Because they do not start reliably, and do not run reliably
until they are warm, they start with an over-rich fuel/air mixture--much
of which is dumped into the water, just like our 2-strokes.  By the time
they warm up, we turn them off.  We never run them at the tested RPM,
and they never achieve that efficiency.

I'm sorry, Roger and Michael, if you find this thread frustrating, but
you are slanting your statistics, and presenting as fact information
that is inaccurate.

When I have to buy another engine it will be as reliable, fuel
efficient, and environmentally friendly as possible.  But for people who
have to make that decision today, it's not so clear which way to go.  I
don't think someone should spend 10% of the value of a boat to buy a
brand new 4-stroke engine which will seldom be used, cannot be counted
on, and will not be nearly as environmentally superior to an older,
cheaper 2-stroke, as your posting would lead new Rhodes owners to
believe.

There.  I've said my piece.  Nothing more on this thread from me.

Today.

Bill Effros

Well, I'm glad that we are going to finally clean up our lakes and
waterways. 
I still think the original legislation was passed to get rid of those
pesky 
personal watercraft, but the industry will adapt and conquer.
By the time my 2 cycleTohatsu bites the dust, they should have all the 
problems worked out of the four strokes.

Rummy
