Thought I was sold on the duals. But I've been told that alot of guys are having issues keeping them tuned? Are the duals worth the extra $$?

I can almost bet you craig he's gonna say black death intake with a good Cody special port job, port matched to the intake manifold with some porting and polishing on that.

That's the best explanation I think I've ever heard.

stick around, you'll learn alot from this guy, wealth of knowledge with these motors.

One that will flow well, the evt was pretty good but it needed a bigger plenum and a better transition to the heads, a spacer works well. Still a hoss.

Now are you talking about a spacer between the carb and intake or a spacer between the intake and heads

Carb and intake

I prefer the single as well- better on the bottom end.

I also prefer the position of the carb on top of the motor w/ brush guard for where I run. Less chance of it getting swamped in rough water and the air filters taking impacts from brush. My grab bar is as much a shield for the driver as it is for a handle so my cowling takes alot of impacts.

I have the duals on mine and haven't had any issues keeping them tunes in the 123 hours I have on the engine now. But if I had to do it again, I'd go with the single. The bottom end on my buddy's boat with a single is a lot better than mine.
