21 Outrigger pipe length starting point

[Shane Bastick]

Does anyone have a good starting point for pipe length for a 21 Outrigger, I have a CMB 21 VAC powered rigger using 21 AA pipes

any recommendations are greatly appreciated - i know this can vary with engine brand and hull type

Correct me if wrong but I believe the CMB line is a rear exhaust engine. So that hand tool will not work for this style engine, its for the wrap around exhaust engines!

I run my vac 21 just over 7 3/4 in. 8 in is a great starting point like Greg said. Ex is out back but it is front ex engine.

7 3/4 was with cmb nitro pipe though. (not the AA pipe)
