Hi Ted,
I don't think we're quite ready to repower yet but have given it some thought.
We have the larger 9.9's, I believe their 323cc's. The new 9.9's are 212 cc's,
I wonder if that will make a significant diffrence in speed. From what I've
seen the 15 or 20hp would fit in the engine box but they only come in 15 or 20"
shafts. Anyone out there know if there is a shaft extension for these motors? I
would like a little more speed under power, and it would be really nice to be
able to run one motor at a good clip. The 15 or 20hp doesn't come with the high
thrust gearing but you can get a larger diameter high thrust prop for them.
Just some thoughts.
By the way were are you heading to? AJ

Some say that when it rains it pours.
We made it from Miami to Savannah, GA with comfortable early summer weather.
Now the afternoon thunder storms have become the daily pattern. And.....I
think we might have burned up one of the motors. One of the 10 year old
Yamaha's billows gray smoke from the exhaust port, make a tinny rattle, an
stalls after about one minute. I'm still investigating the cause and severity
of the problem but thought it would be a good idea to get the "scoaa troup"
responding about replacing the Yamaha's with new ones. I have read on this
post that the proper replacement is the 9.9 GEX. If I need to replace one, I
will most likely replace them both. No need to go through the expense and down
time again any time soon. We would like to get on with our first lengthy
cruise.
Your experience and thoughts.
Ted
