    Diagram for coolant system?

    I have the old engine, just in pieces. I intended to use the block from the vortec and the external parts from the original Mercruiser, (I think it is). I will get some pics to post.

    Diagram for coolant system?

    Sure wish there was! I appreciate all of you taking the time to answer. I'm collecting all of this great info. I figured it was gonna be a big job. I just want to get it right. I appreciate any advice. A good manual of a marine engine might help for starters.

    I appreciate all of the info. The boat came to me with the engine already torn down and I saw a huge weld on the inside of the block. I decided to replace it with a 350 vortec engine I had.
