How long do risers and manifolds last on freshwater cooled engines? I have a 4.3 GM Vortec in my boat. It lives on the Fraser mostly but does make a couple of one week trips to Bamfield every year.
It gets flushed with freshwater if ever in the salt.
Temps all seem normal and no external leaks anywhere.
The boat is a 2000 model,these are original units.
I know not being raw water cooled helps immensely,but how long?
