Mercruiser 5.0 upgrade to 5.7 Vortec
I recently purchased this 1996 2300SC knowing thr engine had major issues when I got it ( pulled the dipstick to check the oil and water came out instead).
Instead of trying to fix this engine I decided now woild be thr time for an upgrade. Even though Ive never even ridden in this boat Im gonna go iut on a limb and say the 5.0 non vortec with a 2 barrel carb is underpowered.
This past weekend I turned on pandora, brought a handful of tools on board and went to town, getting the old engine stripped and ready to oull iut. During the disassembly, I now aee why the engine failed or at least what the end tesult was. The was a huge crack on the starboard side of the block, below the head. Im attaching pictures of the teardown.
Aside from the manifolds, risers, and bolt on accessories, everything will be replaced.
