Fishing season is probably officially over for me for the year and just got back from local dealer looking at outboards. I have 1983 22' Revenge Cuddy with 1983 175 HP Evinrude. I have been thinking about repowering as I purchased 9.9 Yamaha kicker last spring and would like to be able to run it off my main tank. I found a real sweet 2000 Yamaha 200 OX66 for sale with less than 50 hours. It was purchased by a fellow that seldom uses his boat and decided he needed a four stroke so he traded it. My Revenge is rated for 240 hp but "think" 200 hp would be adequate. The reason I say this is I've been running the old Rude for a couple years now and usually haven't had to worry about being underpowered. It cruises great at 25 mph on gps. I trust the dealer as he has been straight with me in the past.

I was looking for a 225 hp but haven't been able to find a late model for a reasonable price. He seems to have it priced right and threw in stainless prop which was on it for $7695. He is also willing to store it for me till spring as I have a little transom weld problem to take care of. I realize I will have to purchase controls, cables, ignition harness and was told my hydraulic steering and mounting holes would probably be an easy changeover.

Is there anything I appear to be overlooking? Does anybody have any feedback on a similar setup for performance? Is anybody interested in a good old Rude?

The Yamaha Ox66 engines are great great engines. Very reliable and gutsy engines.

Mine (a 250hp Yamaha) starts as fast as a car engine, even in 20 degree weather.

I need to let the guy know by Tuesday if I am going to take it. I am doing some measurements for cabling and binnicle mounts right now. Froze last night so starting to button things up for the year. I understand there is an auxilliary oil tank that goes with the motor. Where would one locate that? I relocated my batteries into the cuddy, removed the rear seat and really cleared out the back of the boat and by eliminating the spare tank for the kicker I had hoped to have it wide open. What could I expect for WOT on this setup?

You can locate the oil tank anywhere you can find space. As a rule of thumb, however, I like to have mine as close to the engine as possible to keep the lines short. In my 1986 Revenge, the oil tank is located on the port side, stern corner inboard of the splash well, about two to three feet from the motor.

You'll probably see a top speed of about 40 mph propped right with a nice cruise at 25 - 27 mph turning about 3500 rpm.

I have 1999 ox66 225. Paid $12k new with controls and prop. I did not realize that they made ox66 after 1999. Been a great engine. I mounted oil tank in stern upper level of bilge. Had an aluminum cover made for oil tank and battery to keep water away. 1989 22' OR.

Actually they still sell the 200 Saltwater Series II ox66. Yamaha discontinued the 225 in '03. I missed out on an '01 225 last summer for 10K. It was there for a year but I didn't have the cash at the time. It is kind of hard to justify that kind of dollars for a 1983 boat but I do plan on hanging onto it till I can't handle it any more which may be quite some time...hopefully.

I generally stay within 20 miles of the harbor and I troll with the 9.9 all the time. I installed an hourmeter this spring when I installed the motor and ended up with 156 hours. Not bad for 2 weekend trips to Lake Superior and 3 trips to Lake Michigan!!

John- I maybe able to help you on the Yamaha 200 Ox66 since I just repowered my 22' '86 Outrage with a 2003 model. The Yamaha replaced an old Johnson 225 that I donated for taxes.
So far I have 15 hours on the Yamaha and love it. The engine has far more power than the tired Johnson 225, in fact my son has told me to take it easy on him when pulling him up on a ski/or wakeboard. What surprised me more than the additional power over the Johnson (carb) was how quiet the Yamaha happens to be. It strikes me from the sound perspective to be more toward the DFI in sound than the coffee grind carb V6's. Also, the engine is 453 pounds, a good 50 pounds lighter than the Johnson which I suspect accounts for part of its quick performance out of the hole. Cuurently, I am running an aluminum 15'x 17'pitch prop- might buy a 19' pitch SS eventually but I am still evaluating the top end. Currently trimmed out the engine turns 5400 rpms with the aluminum 17'pitch. We shall see.
FYI I paid less than 10K for the engine (03) with 2 years of warrantee. You be the judge as to how these $$'s relate to the same engine 2 yrs older with 50hrs on it. Good luck. David

I too repowered my '90 22' OR with a 2002 225 OX66, SS Yam 19" prop, mounted one hole down...5000 rpm, about 46 mph, cruise at 3100-3200 = 25-28 mph, 3+ mpg. Love it!!! I tried the 17 prop and went too high...5800 rpm. I mounted my oil res. under the console.

Thanks for the replies, guys. The new prices on outboards must vary greatly across the states. I was just looking at some info on them. I thought the 200/225 shared the same block but apparently not. The 200 is 2.6 liter and 225 is 3.1 liter. The 200 shares same as the 150! The 200 is also 30# lighter than the 225. Weight is a consideration with notched transom.

David, what kind of wot and cruising speed do you find the best? Sounds like you got a great deal on your 200!!

John- The Yamaha 200 seems to have a sweet spot for cruising at about 3800-4000 rpms with the aluminum 17'pitch prop- speed at this rpm I don't know for certain. I too have my oil container in the center console. With the engine rigging I had new Yamaha gauges installed- analog tach, volt meter, water pressure, and engine hour meter. The original OMC speedo remains and has been rigged to work
by my mechanic- how accurate???. Picked up all the gauges new at a marine surplus shop for about 50% off Yamaha list. E mail me and I will give you the fellows direct telephone number- he has more gauges.

With regard to the price, I too was about to buy a 2 year old, used but nice Yamaha 200 off a Contender. The owner was repowering with HPDI's. He wanted $7500. 50 hrs and just out of warrantee. I was talking with a couple mechanics in Central Florida about rigging the preowned engine- one also deals new boats. He said, look at this new Yamaha 200 on the back of one of his new boats. We struck up a price, and he took it off his boat and rigged it on mine. His motivation was to reduce the price of the new boat by putting a Yamaha 150 on it, or just selling without power- giving the buyer an option. Anyway, I felt
the price with warrantee put me close to the price for the
used, unwarranteed engine.

Like I said previously, I am studying the wot rpms with the 17 pitch at this time. Regardless, whether I settle on a 17' or 19'- all a 22 OR needs is 200 hp. With half a tank
of gas the boat screams out of the hole. I can actually run my AM/FM radio and hear it with the new engine.

Good luck
