Hey all..Picked up the second boat in my sig for parts..I was searching for a donor long block for the 1988..
As I read I get the idea that there were changes over the years..
I am looking to find out if I can mix and match parts between this 75 and 88 in case I can only muster up certain good parts from each motor..
So far I have torn into the 75 ..Looks like it took water in .Exhaust ports on the head had sighns of water damage .
Bottom end was stuck..Have since pulled crank and it is in great shape and so were the bearings ..I am hopefull that I have a usable block here..Hardly and cylinder ridge, maybe just carbon.. Hoping to pop the pistons and hopefully get away with a clean/check, bearing and re ring...
Just unsure of the compatability with the 88 3.0 head??? Not sure but I think I read the manifold port orientaion may be diff as well between the years???
Any help would be greatly appreciated..Still searching the forums..
