local area dealer has left over new 1999 150 hp merc engines for a great price, under 5K. Can these engines be converted to CR engines, If so how ahd what is approximate cost? thanks JIM

Unless you are thinking of using the motor as 1/2 of a dual set up and already have a counter-rotating motor, why change anything?

Standard motor torques one way, counter rotator torques the other; you might have to shift a little weight if you don't have trim tabs but probably not, and you'd have to get used to docking with a prop that spins opposite, but even that is not as big a deal with an OB as it is with an IB.

Question is fuzzy. Are the engines CR now or do you want to convert to CR?

If not CR and you want to set up twins, you can rebuild the one lower unit for under $1k. You can also run hydraulic steering and leave as-is. Cr is great but until the mid-80' NEVER existed in outboards so it is not that "crucial", more like a comfort.

Sorry for the fuzzy question. I am considering a twin engine set up on a boat that presently has a single with hydraulic steering. In previous posts forum members said a twin set up required a CR engine. The engines that I referred to in this thread are not CR engines. If my boat has hydraulic steering, is there any reason not to mount twin Non-Cr engines? thanks JIM

Do yourself a big favor.....BUY THOSE ENGINES YESTERDAY! Mount them and run them. If you decide after a day, week, year that the twins pull too hard or list too much, have the one lower unit rebuilt to CR standards. I assume you do not need to replace everything, just the gears. housiong is still identical, etc. With that and a prop....maybe a grand and you have CR engines but why not mount them as-is and try them that way. At $5k a pop, you should have already bought them:)

If these are "still-in-the-box" new 150 "99s for under $5k, I think you should tell the dealer to "stuff it". In fact, I'm so outraged, e-mail me the name, number and address of this so-and-so, and I'll tell him off for you personally.

Just trying to do my part for a fellow enthusiast. ;)

Do you remember Roseanne Rosanna-Danna on Saturday night live? Her shtick was to take off on a long impassioned harangue about some subject that she had misunderstood by virtue of inverting two words in the subject line, or mistaking one word for another because they sounded alike or something equally simple, the effect being that she would be haranguing about something entirely different than the original subject and her standing comment when someone pointed out her mistake at the end of her tirade was, "Never mind..."

Well, "Never mind..."

I completely mis-read your question and would like Scotty to kindly beam me up now...

Like I said....question was a tad fuzzy. You did fine Kingfish because I thought the same thing but decided to see if that was his intention. Kinda like I did on another fuzzy question today but instead was beaten to death by Bernard Getz wannabys. Anyway....Thank you everyone on this thread for treating me with dignity so I could answer the question as well as possible.

I agree with BS and if these are for a 25'O... perfect. Deal with the CR later if you really need to.

Be sure to check out the shaft lengths relative to the application. Until 1987, you could only power a 25 Outrage with twin 20" non-counter rotating engines. With a side mount hydraulic cylinder, installed between the engines and in a reversed tilt tube on starboard engine, for $10 grand I would go for it. Steering pull will not be bad at all. See Reference section on transom jacks for steering info.
