I am far from an authority on the subject, but will give you my two cents. I've owned a 1988 OR20 with matching Johnson 200. Boat did 44mph on its best day with mediocre SS OMC prop. 200 definitely worked well on that boat, would I go less, not unless it they made a 175 that shaved 150 pounds off the back. So the short answer is NO. Would I have liked more...an emphatic YES.
One of the great things about Classic Outrages is their terrific power to weight ratios. Why sacrifice that? Other benefits are better fuel economy at cruise with more hp as it works less hard. Another benefit is resale, you will take a serious hit, if you actually price it at point that it will move and not these dream list prices on many of them you see out there) with less than max hp. In this case they don't make a 240 but 200 would be minimum IMO to avoid this. 225 much better.
The superior design and setup of these boats also makes them somewhat susceptible to stern weight. No you won't sink it or ruin it, but it may not perform or ride like it otherwise would with a four stroke on it. Also, these boats are pretty light to begin with, I'm not sure a 4s would give you much better, if any, mpg than a DI motor. Also, why ruin that power to weight performance factor by a heavy 4s and mediocre torque curve.
Lastly, besides being unsinkable and safe they are also FUN. In my book, and its just my opinion, why throw out your fun by underpowering this rig. I just bought a 22 with 225EFI Yam. If the engine goes, I'll research the insurance premiums and engine weights and seriously consider a 250hp. Not to just go blazing when its calm, but for the great hole shot, easy (on the engine) cruise speeds, higher cruise speeds, more useable engine rpm choices, and yes the fun of firewalling that throttle. I'll definitely never go less than 225.
There is much debate on brands of engines to go with. My opinion, to keep it simple, is to spring for the bucks and go with a new DI engine. Yam, Rude, Merc... your choice... all are probably fine if you run the right oil and do your maintenance etc. Pick a dealer that you like to work with that is close by and go with the brand they sell. If more than one choice of brand still, start price shopping. Whether your 225 is M, Y or E you're boat will rock.
Hope this helps. Good luck.
