Hey everyone, I just picked up my first inboard boat a few weeks ago. Itís a 1976 Century Sabre with a 318. It uses a raw water cooling system that I am currently going through to variety itís condition and functionality.
I have a quick question about the brass tubes in the exhaust manifolds. In one manifold the tube spins but does not pull out and on the other it is set and does not rotate. Iím assuring they are not supposed to spin around, but Iím not sure how they are secured in place. Are they pressed in somehow?
Any input would be appreciated, thanks!
