Our water lift muffler has sprung a leak here and there and we are looking to replace it. It is currently a Centek I believe, 3.5 inch in and out. The Lehman manifold elbow is 3.5 inches in diameter
However when I took the hose off I found that what I thought I was a hose splice is actually a custom reducer and that the old hose that goes all the way to the back of the boat is only 3" diameter. My plan was to replace all the way to the stern with new hose.
The boat is a 1967 and several things have been 'modified' over the years so now I am left wondering what size should be in there. To complicate matters Centek seems to say for our 120 the hp rating should be a 4", 3.5 is rated at 85 hp.
What are the other 32's out there running for size? Any shared info would be appreciated, thanks.
