Hi Phil
We be talking 2 or 4 stroke?
If you are talking 4 stroke they are a great kicker
I am on my second 9.9 Yamaha high thrust since I bought my AS in 90.
First one I would guess I had 2000 hours or more on it.
The 9.9 4 stroke on my boat now I bought new in 2001.
I have a hour meter on this one...reads over 2000 hours....runs like a top.
I change oil every 100 hours and I think I changed the water pump twice.
Great motors as long as you maintain em
They have got me back home more than once when the main engine took a dump
