newbie engine removal. 3.8 to 4.3

[Goat_hauler]

Well Im new here but this looms like a good forum to ask, I got a 1985 Chris craft with a 3.8 merc in it. The engine is bad and I can't find another 3.8 so my buddy has a 4.3 were dropping it. Hopefully its a easy swap. My question is can I pull and install the motor without pulling the out drive? And what parts should I Change while the motor is out? The 4.3 is out of a truck so I'm doing brass free plugs and marine he's gaskets. Anything else or anything on the out drive I need to replace? Thanks for your help!!

Also whats this alignment tool? What a!l gaskets will I need to replace?

Sorry, drive MUST be pulled before the engine is removed. The alignment tool is used set the alignment of the engine to the drive... Have a look in the stickies and you'll find my videos on removing and re-installing the drive, also on doing the alignment...

thats quite a project

you'll have to replace all the engine externals too, not just the long block

your best bet is to find a rotten donor boat with a good engine/drive package in it
