Post subject: 9.9 High Thrust vs. 15hp outboard
Archived from groups: rec>boats (more info?)

I own a 22' Grady White with a 225 Yamaha. I need to replace the old
kicker. This engine main purpose is to get me home if the main one breaks
down. I was told that the 4 stroke 9.9hp High Thrust is a better outboard
choice than the 15hp. I cannot understand why an engine that has 33% more
hp would be not one to choose. Is the 9.9 High Thrust the best choice?

The high thrust is the best choice. The 9.9 may not be. I run a Yamaha T-8
high thrust on my 3400# aluminum jet boat. Get hull speed (6.5 mph) at
about 3/4 thottle. The 15 Mariner that it replaced would only get me about
5.5 at full throttle. The motors are designed to move sailboats and
displacement hulls at a lower speed. The T-8 and I think the 9.9 both have
25 hp gear cases, with lower gears. They now have the clearance to run a
bigger diameter, low pitch prop. This keeps the prop from cavitating and
moves the boat better than a small prop with a lot of slippage. As to the
9.9 and T-8, the T-8 has power tilt. You can also get it with remote
throttle. I love not having to reach over and lift the kicker on the OMC
bracket. I now have a fixed bracket and just push the button to tilt the
motor. Is the extra long shaft (25" it think). Mine was about $2300 2
years ago. I think the big Yamaha dealer in Florida sold them at about that
price, no tax and about $90 shipping. They may make a 9.9 power tilt now.<!-- ~MESSAGE_AFTER~ -->

I bought the Honda 9.9 a year or so ago. An acquaintance advised me to
not by the high thrust model, but to buy the high thrust prop only.
(Maybe Honda calls it Power Thrust) By doing so I saved about $75 as I
recall. The only difference? I didn't get the "Power Thrust" decal on
the cowling. And I'm ahead by one standard prop which is my spare.

Maybe Yamaha's marketing of the bigger prop is as silly as Honda's?

"high thrust" means the prop turns slower, nothing more.

Horsepower, on the other hand, MEANS thrust multiplied by rpm.

you are right, hp is hp and 15 of 'em is more than 9.9 of 'em.

"high thrust" vs hp is the old sales technique, "If you can't dazzle them with
brilliance, baffle them with bullshit."

hp is hp.

billie, be quiet. you don't have a clew what the relationship is between
horsepower and thrust. knock it off. the guy asked a valid question and you
want to babble on like you are on your 5th beer.

a non-sense answer, billie. however, no more than what can be expected of you.

You can only put so much diameter prop on the leg. The High Thrust have a
bigger area for prop and the gear it down so it turns the bigger prop
slower. Less slip.

Jaxass, you be quiet, you do not have a clue about anything! What happens
if you put a 250 HP O/B with a small surface piercing prop on the boat.
Good kicker? Lots more HP!

billie, attempting rational discussion with you is a useless as attempting such

So, Genie-ass, can you answer the very easy question?

Do you know the difference between torque and horsepower?

Do you know the difference between an over-square and an under-square
engine?

billie, and you and dog pile are a pair. but let me answer your questions.

 >Do you know the difference between torque and horsepower?

This question was answered, by me, a couple posts back. apparently, you either
were not paying attention, or you are not capable of understanding. if the
later, ask a high school kid to explain it to you.
next:

 >Do you know the difference between an over-square and an under-square

yes. and, like tens of thousands of others, I knew the difference while still
an early teenager.

next?
