My risers on my 05 340 were definitely changed. I can see they are actually taking a smaller foot print than the originals. They also are definitely not cast, appear to be very shiney to look at as opposed to the more typical matted finish on the cast ones. A very knowledgeable friend says they are either stainless or some kind of copper material and do not degrade like the cast ones do. They therefore don't need the 3-5 year replacement. Does anyone have any thoughts here as to maintenance? Does this sound correct? Also, the manifolds are mercruiser. The motors are the 8.1 horizons. Aren't the manis fresh water cooled which would require far less maintenance ? I recently looked at mani temps under full load conditions. Hot spots were about 138 degrees. Any thoughts greatly appreciated. Thx.
