The subject boat is a 22'outrage powered by a 225 yamaha 1990 small block 158cc. The engine has had some troubling issues so I am planning on repowering soon.

In light of all the issues with the high tech injection motors from the big 3 I would like to stick with simple fuel injection systems.

I'm thinking that a new 200 158cc ox66 yamaha would be very close to the motor that is currently on the boat. I'm not certain that I would really notice the small drop in hp compared to the increased performance in a new injected power plant. The new 3.1 liter 225 big block yamahas weigh more and displace more fuel and for a minor 25 hp it probably isn't woth it.

What do you guys think?

By the way I think I want to stay with yamaha power on this rig!

Cost IS a factor!

I think that the 200 Ox66 EFI should be a fine motor for the Outrage although if you can get your hands on a 225 with the 3.1 liter block, that extra displacement is a better setup in my opinion. The extra weight (50 lbs) is not a problem and it is probably about a gallon per hour more in fuel consumption at the typical crusing speeds of 25 to 30 mph. The 225 will likely last longer if you are planning to keep it for a while because it isn't going to work as hard as the 200. I run a 2000 3.1 liter 225 on my 22' Revenge and I think that is a great setup.

Watch out on the 225 Yamahas of the early '90s vintage for corroding shift shaft problems.

I run a 2001 225 Saltwater Series II OX66 on my 22' Outrage. Sweet, powerful, very reliable engine. She does like to chug her gas though.

The engine that is on there has reportedly had the shift-shaft replaced. When I first went to see the boat the engine would not turn over. The seller said it was a frozen bushing somewhere on the drive shaft and was replaced. Does anyone know what exactly this problem was and if it is common to this model?

Having driven almost identical boats powered by both the Ox-66 200 and the Ox-66 225, I can say that the difference in torque between the two motors is incredible. One reference in which you may be interested is David Pascoe's test of a GW Sailfish 27 powered by pairs of these two engines. I hope that this helps.
