9.9 High Thrust vs. 15hp outboard
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? Jim |

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. |
"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 bull****." hp is hp. I own a 22' Grady White with a 225 Yamaha.

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? Dale |
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. wrote in message oups.com... I bought the Honda 9.9 a year or so ago.

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, and you and dog pile are a pair. but let me answer your questions.
So, Genie-ass, can you answer the very easy question? 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 engine? yes. and, like tens of thousands of others, I knew the difference while still an early teenager. next?

No Jaxass you did not answer the thrust / RPM question completely. And you
explain to me how over-sq and under-sq differ. And why an over-sq engine spins faster. Hint on your test. Use an engine with a 2" bore and a 20' stroke.

Just because a motor is rated 15HP at some RPM does not mean you can actually use it at 15HP in your application. |

billie, if you were not pie-eyed drunk, maybe you would understand the easy
things. "easy things" does seem to include that fact that "high thrust" has no meaning in and of itself. 500# of thrust at 50 rpm (on a 6" pitch prop) is less hp than 50# thust at 500 rpm (on an 8" pitch prop). wanna tell us just how many degrees crank rotation the piston is stopped BDC on an engine with a "long" connecting rod as compared to the same engine with a "short" rod (something most any woman you have every known complained about, at least behind your back).
