Yamaha F150 break-in
 

I am about to purchase a Hydra-Sports 202DC with a Yamaha F150 4
stroke.
I have read the beak-in procedure.
1hr at 2000 rpm , 1hr at 3000 and the next 8 hrs no full throttle for
more than 5 mins.

My question is; When pre-purchase water testing, how much or little
damage is sustained while the sales guy or I run a new motor at full
throttle for a few minutes to see full speed and other handling
characteristics of the boat

I suggest you follow the directions to the letter.

Thanks for the reply but it doesn't address my question.

Answering your specific question would be difficult for anyone.

The Yamaha computer will know you violated the break-in procedures. If
this is of no concern, go for it.

I followed the procedures with my Yamaha 150, although I did take it
up to about 3500 for perhaps two minutes during my 'test drive'. No
way would I take it to wide open throttle for a 'few minutes'. But, as
to the damage, or lack thereof, who knows?

Thanks for the responses.
Forgot about the computer. duh

It does seem wise to be judicious with WOT.
Water test not till 3/21.

I'm gonna by it unless it sinks or doesn't work at the splash.

It's a leftover 2008 model and is priced right.

I really think WOT takes time off the life of an engine, particularly
a 4 stroke but that may just be me..

Automotive 4 strokes run at WOT for any length of time have very short
lives. I've been told by a number of people who should know that
3400 to 3600 should be about the max for normal operation, maybe 4000
for outboards.

Of course not, you've just met Harry. Vague at best because he doesn't
know anything, but wants people to think he knows everything! You do
realize that Harry claims to have a degree in Mechanical Engineering,
don't you? But, he also claims to have a degree from Yale, claims his
wife has two doctor degrees, his father once took a runabout across
the Atlantic in winter and got a fireboat welcome on his return to
NYC, he claims to have owned many, many boats, rounded the horn single
handed, sailed from SF to Hawaii, and on and on......

No, I didn't just meet Harry. I have never met him, but I have been
lurking here for 10 yrs, posting once or twice a year, while you guys
talk about everything but boats.
I first posted when I bought a new 1999 Luhrs Tournament 320 and Harry
was the first to respond.
Sold that boat 5 years ago and have been using my sisters 33ft
cruiser.
Time for a small boat to play with the grandkids.
This is hardly my first boat or outboard but it is my first 4 stroke.
