Whose money are we spending?

I have twin Yamaha 150's that can get me up to the mid 40's.

they are 8 years old.

My guess would be that twin 150 eTec's would get me in the low 50's and probably 30% better on gas.

Twin 200's would be what, mid 50's+?

That is some choice you have.

Twin 200 would be nice if you just want to go fast,If I was repowering id go twin 150's, less money,less weight,150 would push it beautifully, especially etec's they got plenty power.

the 60 degree 150,175 and 200 etec's are the same weight. Might as well put as much as you can on it. I am.

First we need to know if you have a cc or Scepter style. What is it you want out of your boat? Top speed, range, fuel economy? As many on the board here know I just have little 115 4 stroke suzi's and they perform wonderfully. 25k cruise at 4k burning 10.5 gallons. If I bump the throttle up to 5k rpm's I can run about 31-32kts and in the gulf of mexico in a 2 foot chop that's about the fastest I can run comfortably. 115's will cost you about 15.5k for the pair 150 Suzki's about 19k Twin 200 4 strokes or etec's are going to weigh roughly 1000-1200lbs. That is really pushing the limit for the CC a Scepter may handle it better due to their forward weight of the cabin.

I think my advice for you if you want a good power to weight ratio are the Suzuki 175's. You will probably be in the low to mid 50's. I don't know what etec's cost but someone recently told me a 150 etec is more expensive than a 150 Yamaha. Good luck with whatever you choose and post some pix here!
