It depends on the type of bow thruster.....
write type and model and should be easy to find.
these are for Max Power:

thanks for reply, but the NC11 is already pre "tubed", it looks like cover plates glued over the tube, so I'm trying to find out what size that tube is so I can look at options.

Which brand is it??
check on google

the tube is sized for a 185mm bow thruster
