I have a hose on the inside of the boat that is plugged and goes through the drive and I can find the other en hanging in the air
I am assuming that it was for a old bravo that had the speedo pick up in the drive
Is there a plug kit for the gimbal assembly so I can just remove the tube?

Yes, it takes a 1/8 " brass pipe plug

thanks
is it from the inside or outside
wont be to hard to figure out
