I have one relatively new gm 260 5.7 engine and one old engine that has a cracked block.

Hi,
I have a '86 Sundancer 300.
I have to change all four manifolds and was thinking that it may be a good time to switch to a closed cooling system. The boat was in fresh water and will be used on the west coast in the ocean now. Has anyone done this with good success?
4x exhaust manifolds

Thanks

Best to take it one step at a time.
Thanks for the input.
You are right. I have also noticed that all four exhaust manifolds are cracked. Fun, fun, fun..................no boating this summer, I guess...............
Do you have any suggestions for parts at a reasonable price?
My starboard engine freeze plug popped out. Has anyone put a freeze plug in without pulling the engine out? Any tips?
