Any general comments on the performance/reliability/fuel usage/weight of OMC V8-250HP? I always thought they had a bad reputation, but my local OMC shop seems to like them. Of course he may make plenty fixing them...

To be blunt, they were dogs, heavy and not very powerful for their size, and never went over very well. Mercury's 3.0 liter V-6's will run rings around them. I definitely would not touch them, and would doubt that Bombardier will be supporting the parts for them. Pretty much an obsolete engine. And only the 27' hull Whaler drive was designed to accomodate them. Not recommended at all for a 25 Outrage.

That is what I thought. I was surprised when my local OMC guy said they where reliable. He didn’t seem to know about how they performed vs. other 225/250s. Of course he may like the V8s because of the high repair bills.

What to you think about '94-'97 OMC loop charged CR 150 HP’s?

From what I've heard, the 60 degree OMC V-6's are excellent, powerful engines. People who have them like them. They won't keep up with a pair of Merc 200's, inspite of the larger cubes, however.

They should push the 25 Whaler Drive about 45-48. The Whaler drive models have more bottom drag than the notched transom boats, so I would still recommend the 200's if possible. But I think you would be happy with the 150's also.

Just as new purchase guideline, you can buy Merc 150's new for $7500 each.

What a dilemma. For my budget I have found ether a single '86-'87 merc that matches my 200, I would end up with a non counter-rotation setup. Or a pair of newer low-hour CR-150s! From reading the pro “Merc 200” threads it sounds like even an ’87 Mercury will significantly out perform a brand new carb based Johnson 150… It one of those decisions money would clearly fix… I should wait for more money to grow but my current single 200 is tooo weak for the swells…

Ahhh, what to do, what to do...

If new carb-150's are $7500 what do 200 or 225s go for.

Of course I can only buy opti-max's here in clean-water land and the two local merc dealers say I can have a pair at a real bargin for 23K. (same for the 2002 "Bomb-barts")
