20 hydro pipe length question please

[vision craft boats]

I have a 20 cmd eagle I have been working on for a while and was checking to see where to start the pipe length at with a 7 port Nova, using a cooper quiet pipe. And also where you are measuring from. Thanks in advance, Shawn

hi shawn

i would start 8 1/4 and go from there.. but to be honest. you will probably want to loose that pipe.. they don't work to well in a hydro.. the best USER FRIENDLY pipe is still the OPS 3280 ran it for YR's before i started running the s-pipe

to measure you can buy a guage that is on www.woodrcboatproducts.com

or measure in line from the plug to the weld on the pipe i think is something like 3 1/2"

if i am not mistaken. but i am not sure

Shawn,

Start with a 1445 w/3.46" of cup and set the pipe at

8" or measure 3" from the center of the engine.

Have Fun,

Happy New Year,

3 1/2 from the plug to the weld on the pipe & ops 3280 pipe is the ticket
