My thought has always been, if I replace the motors would the boat be worth what I put into it and go from there....I had OX 66 250s on my 26 Regulator and put 1700hours on them...The o2 sensors were replaced a few times but except for the fuel bills they were great....There thirsty things...if you do sell the motors to repower call a few marine contractors first..they love to put them on there barges...

They are good motors. 500 hours is ok. Check them out for corrosion. This is all obvious. Of all the used engines, these are the best you can get. Run them for a few years or until you are annoyed with the fuel bill and then repower. Pay no more than 5-8k for them and you can win because if you keep them running you can sell them for what you paid for them. People want them and they sell quickly. They are very easy to work on. If they were trailer kept, thatís even better and can be in great condition. Get them checked out thoroughly.

I think they are the best 2 stroke engine that Yamaha made. Relatively simple, easy to work on. I bought the same year, HP and basically same hours two years ago. I ran that engine one year and loved it, then moved up and sold the boat. I wouldn't hesitate to buy a boat with those engines

"Of all the used engines, these are the best you can get. "

There are more Gradys at the marina with these old bad boys hanging off the back, than any other brand.....and there's a reason.

Prolly the best engines Yamaha ever made. I would look for maintenance records and have compression tests done, then go fishing.

This is a good way of looking at it. To help you in your analysis, here is a repower estimate to chew on. I recently asked a dealer what it would cost for him to completely install brand new twin Yamaha 200 hp motors on my boat. He quoted me $40,000 complete.

I run the predecessor to those motors, the 225 Saltwater Series II (carbed). 1997s. I was hesitant at first but they get much better mpg than I expected and are supposedly bulletproof. The math will never work out with replacing so I'm going to run them until they die which unfortunately may be never.

My 225 Saltwater Series II was EFI. Agree on being good motors overall though.

I did, here's my story:

2000 Grady Gulfstream with OX66 200s. I bought the boat in 2016 and the engines ran good, had 800 hrs. Everything passed on the survey, good compression and no issues. When we negotiated the price I placed very little value on the motors because I figured I will have to repower soon. Sure enough the 2nd summer the port motor blew a piston out the side of the block. To be honest I didn't like the engines to begin with. I was only getting 1.2MPG and the smoke and noise was annoying. I found a local used engine broker, he gave me $1k for the blown motor and $3500 for the running. My mechanic told me if I repower with a pair of pre-2012 Yamahas I could use my old cables and gauges. This saved a bunch. It took some work but I found two 2010 F150s on CL. I paid $7200 for the Florida motor (650hrs) and $7500 for the Minnesota motor (350hrs). I paid my mechanic $1800 to switch out the motors and install new balancers. So net it cost me $12k to upgrade-and here's the best part-the value of the boat went up $15k! AND I'm now getting 2MPG and the noise and smoke are drastically reduced. So in my mind this was a home run. If you like the boat you might want plan on repower with a good used motor right out of the gate.

I have a set of 1999 225 OX66s and as much as I would love to re power, they still have enough power to jump my 7000 lbs boat on a plane and push it to 52 mph. They both start at the bump of the key, and as long as you keep the filters clean, and the pesky oil tank filter clean, mine seem indestructible. I can cruise at 1.5 mpg. It takes ALOT of gas to make up for spending 40k on a repower. I do not hesitate to go offshore with mine. I would have an OX66 over a 4S 225 of less years any day.

Good advice on here. I love my 01í ox66 250s, hand tools can do all the work on them I need. Super basic and I really get confidence from that. No smoke after start up, quiet at idle. Pennzoil XLF oil. Never skipped a beat. Extra fuel and oil is way cheaper than new motors.

I will upgrade to some zuk 200s at some point in the future but not right now!

I had a 2000 200 HP OX66 I bought new on new 21 Regulator - ran 2000+ hours - repowered w F200 in 2012. The OX66 drank twice as much gas as the F200 4 cylinder 4 stroke plus oil - that said it was a reliable engine! Guy who bought my used motor had it crap out 3 weeks later . . .

Maybe mine are just Saltwater Series then, they are definitely not the OX66 or fuel injected.

My 2002 OX66 200hp blew up last year unexpectedly. Totally sucked. I used ring free religiously and the expensive Yamaha 2 stroke oil. Those hours seem suspiciously very low. For one, I didnít think those motors had hour meters, so thereís a question about where that info is coming from. Also, like others have said, maybe they have been rotting unused for long periods of time, which isnít great either.

I switched up to an F225 four stroke (which has its own issues), but Iím never looking back. While 2 stroke oil smoke does smell like fun, if the wind is going the wrong way it can make trolling much less fun when youíre sucking it down all day. The four stroke is so much quieter too. I miss the instant power of the OX66, but I would never go back.
