Walt,

ABC 1614/3 Chopper and reduce the trailing edge cup just a little bit.

8" pipe for the 21 should get you close.

The 45's are running X-450/3's or X-452/3's.

Have Fun Testing,

Mark

Like Mark said the 1614 is awesome when i had my ducer i put that on it man did it light up good combo

I agree with the 1614/3 for a seaducer. The 2 440/3's i have for my speedmaster are not as fast & don't lift/set the 'ducer as well.

Walt the s pipe doesnt work well on a mono it is a hydro pipe at least that was my test experence

Walt,

All of this advice,,, and no one has asked what engines you will be running?????

On my 21 Ducer with a CMB RSv 07 Valvola I had great success with to AB 21 Fat Pipe @ 8-1/4" Octura X440/3 I ran the ABC prop, I just didn't really like it.

Remember, we run with more heat & humidity than most who are offering advice.

I am now rinning the CMB 21 Nitro pipe, same measurement with one of the 707 "diamond" shaped muffler. good throttleability and great R's

On the 45 Ducer, I'm running a CMB RS45. A great pipe for that engine is the Mac's Exhaust 7.5 Marine Nitro of Muffled pipe.

I have on my Ducer the CMB 45 Nitro pipe also running a X450/3 A X646/3 orks well on SOME 45 ducer mono's

What will you be running for power on each of these?

 

[Walt Barney]

the 21 mono will be run using a N/R 21-35 with turbo plug will try different pipes this week before I go to Atlanta as I live on a large lake and can test at any time, I just jump on my pontoon and go test water is only 30 foot from house, boat stays in boat lift until need to test or go fishing.

PS water does not get hard in winter.

45 seaducer should run real strong on a 450/3 reduced tounge and barr cut 1/8 wide and 1/8 deep. In hot/ sticky weather a 447/3 reduced tounge and barr cut and pinched up quite a bit works real well
