I'm here to share my experience now that my boat is working and on the water. I have seen several questions and discussions on this subject so I figure I would share my experience and with that will pose a question at the end of this post
I bought a 1995 Bayliner boat with a non winterized engine with a cracked block, one head and both exhaust manifold cracked. I figure there is no point in saving the engine. Too far gone
I got myself an engine from a 2002 Chevy S10. I sourced the intake and exhaust manifolds from https://www.michiganmotorz.com/ (the 1995 intake does not fit as I'm sure most of you know)
At first, when I started the process of finding a 4.3 engine for my the boat I didn't know the difference from a marine engine to one from a Chevy truck/van. After I got the engine I learned about the camshaft differences.
I proceeded to install the engine anyway exactly the way it came from the truck. I redid all of the gaskets on the engine by removing the heads and oil pan and cleaned it up very nicely as well.
Since the 2002 engine come with a serpentine belt I removed all pulleys and the water pump. I used the water pump and other components from the old engine. The timing belt cover on a 2002 vortec is plastic and the bolts stick out further. The water pump would not fit with one of the bolt heads in the way. I took one of the bolts by grinding down the head and cut a grove so that I could tighten the bolt with a flat screwdriver.
There were a few other small modifications I had to make but everything works.
For those of you who are highly familiar with the 4.3 engine and knowing the difference between the marine and truck/van engine what difference does it really make once in the boat is on the water?
The engine performance nicely.
I look forward to some feedback
