The only thing you will use from the truck motor is the short block and heads
You will need to install brass core plugs and marine head gaskets.
You will need to swap over your marine stuff from your current motor. Water pump, electrical system, accessory drive, oil pan and dipstick, fuel...
Not sure why you are looking up GM parts on the Mercruiser site. 500% markup
I use a few GM industrial sites to get GM part numbers.
However if rebuilding, my local machine shop
4.3 GM marine cam part number is suspiciously the same as the GM Silverado/S-10 truck cam
Not sure where you are getting your info.

@jimmbo I had an opportunity to tour Barr when working on the Verado CAC. They make castings for Edelbrock, Volvo, PCM and many more. Lots of design commonality across various brands
installing a carb spacer and increasing plenum volume increases low and midrange
BTW, Volvo Penta manifolds and Edelbrock manifolds both come out of the exact same casting boxes at Buddy Barr castings.
Not sure what your issue is with your motor, however I suspect tuning and potentially carb...
Other than making sure the HIN and paperwork match, you have a boat with an OMC stringer in it
Boat brand means nothing to trouble shooting and fixing your issue.
If you are looking for a manual, it doesn't exist other than the OMC factory manual
