You are very lucky.
However, lets consider a few things. How many times have you actually run
this motor for hours straight at wide open. Where were you going? I can't
imagine riding in a boat w/ a 6hp engine running wide open for multiple
hours non stop.
Also, how many actual hours do you have on the engine given you have only
changed the points one time.

Hi,

I just gave up trying to find a used 9.9 4-stroke and bought a Shiny
New Merc
9.9 4-stroke. It's LIGHT!

Anyway, I've always run older 2-strokes and often ran them WOT for hrs
at a
time. Now that I have a new one, I'm more concerned. Are outboards (esp.
4-strokes) designed to run WOT full-time? I know inboards are not, but
what
about outboards?

The manual doesn't say: just describes break-in period. They say for
the
first 10 hrs do not run WOT for more than 5 minutes. After that...?

Both Harry and Tony are right on target concerning their thoughts on
running at WOT. Though I am running a diesel and expect a longer life, I
do
not run at WOT for any length of time.

Consider the following from www.boats.com

In typical marine use, which involves considerable idling and medium
speed
operation with relatively little full throttle use, a gas engine can
expect 2,000 hours before it needs an overhaul. A diesel used in a
similar
fashion might go 5,000 to 7,000 hours before an overhaul is required.
Even
at full throttle, a gas engine is going to need rings and crank bearings
in about 200 hours, while a diesel won't start burning rings or pistons
for 1,000 or more hours.

In a nutshell, continuous running at WOT will likely shorten your
engine
life to a tenth of what might be expected under normal use.




I've run our Johnson 6 hp at WOT for hours on end for over thirty
years... the engine has never been apart and I've changed the points
once... do these engines last 300 years or more with more gentle use?
