Good News! SB engine mystery solved
 

Some of you may remember my previous posts with regards to my 99AT w/350magMPI's....I had overheated during the Jammin on the James PR and had experienced some minor engine noise(ticking, knocking) after changing the sea water pumps & running for several hours. Well, I believe I have found the problem to be a minor gasket leak between the Stainless Marine exhaust manifold and the head. After speaking with a few engine guys about upgrades and my options, I got some help from a source in S.FL and he was right! Thanks Ron P.; what a relief....
Thanks everyone for chiming in......
BTW, I'm keeping the engines stock and spending the $$ on Imco full hydraulic external steering.
Spilman out.....

Good news, wish my engine woes would have been that small.
