Thanks for the reply Tom.
I don't send anything out to be rebuilt, if I own it I fix it, that's how my grandfather taught me to be.
The air orbital sander I have is very light weight, one of the perks of where I work lots of free top shelf tools to take home when they break. Take them home fix them and babammm high dollar tool to work with for dirt cheap.
The air flow is adjustable on mine but I was afraid it would still be to much power for the kind of work that will be needed done on the boat build, but you and others saying it works fine remove's my fear's about it.
