I thought blowers fall under the bigger is always better rule 

you didnt happen to pick that up from riverdad/jason did you?

Ya picked it up from Jason this weekend.

well whats this going on buddy?

  My dads 21' v drive

nice one of these days i will own one of those

Thanks! The boat setup with a turbo 400 trans 3spd and cav plates it should move out good   

  I'm in need of some headers for this deal, the cast iron center risers weigh a ton, anybody running a set of CMI split top headers is it worth going deep in the pocket for these compared too the heavy center risers , I found a deal for a set but they are not cheap.

   Well its not going to be a drop and go setup after all, had to cut the rudder arm for clearance  crank pulley lined right up with it    had to make a bracket for the steering cable also so it lines up with the rudder arm.

hey I  found these on cl http://inlandempire.craigslist.org/boa/2879944266.html

Thanks bud! how bad of idea would it be to run these,it has no hatch right now.

brian that guy is on this site and only asking 400. But with that thing being a v-drive are they gunna work? They might be pointed at the sky.

If they're water jacketed headers, and it appears that is what your looking at, no real problems. Plumbing them is always an issue, not a problem for you, and they do run hotter (to the touch, not to the engine) so make sure they're clear of everything, hatch, seats, engine cover, potential mates, etc.  AND that your bilge blower is working!

Perfect addition, and really required when droppin in a blown engine!

Now the intake side of that...........

     Ray I'm looking at my options for what's headers to go with, I'm looking at a solid used set they're selling for $1000- $2500  for water jacket headers, my question is what about the Bassett threw transom they are not water jacket headers they work off the t valve, so water goes threw only at 3000 RPM'S.

Yeah, enclosed engine, do NOT go with the Bassett's IMHO. Safety over HP in this instance Brian. I'll agree, water jacketed's are pricey, but well worth it in this instance. You have kids, I have kids, Fire doesn't play well with them.

The long and the short of it, we may be discussing somewhere around 60 hp or so going to headers on your blown boat switching from logs to headers? Why not center risers? Far more economical and far less $$$ than water jacketed headers?
 
You won't lose enough HP to even notice, seat of the pants.
