doesn't sound like he deserves a good running boat!! if he can't fricken change oil???
Call your insurance company. When I was spinning wrenches at a shop in Ohio I replaced three 350's one Spring due to improper or un-winterized engines.
Two were covered under the owners insurance policy
Called my State Farm agent and asked if he covered stupidity and he said yes
I had twin inboard cruisers for several seasons up north and did all my own work but heard everyone else's stories. Inside, heated storage and a blizzard takes out power. Now what?
Had 318 Chrysler's in the cruisers and would always just drain everything. Didn't know at the time that they were known to trap water in rear of block. Knowledgeable marina's knew this and stored those boats bow down so the blocks would drain. Mine knew but as I was a smart ass (doing my own work) they didn't tell me Had the boat sold the following Spring and when I fired the motors the 1st time they both blew water out of the bell housings!!! Luckily it just popped the freeze plugs. Turns out my marina made their money off me anyhow.
I'd rather be competitive w/junk I built in the garage than win w/stuff I bought.
1) Pumping the air out of the 496HO is not good enough for a full winterization: especially in those temps. There are dozens of posts on this in the past. The air pressure system is designed to extend your boating season. RTFM. The air pressure system will still leave pockets of water in the system; and that's if it's working right. The actuators go bad.
2) The most vulnerable part of the 496HO system is the heat exchanger. It's very thin inside and one tiny crack compromises everything. If you try and do anything with it now, you are likely to push water into the antifreeze system and then also destroy the block.
Wait until spring, and pull the whole thing apart and pressure check each component; especially the heat exchanger. However, it's almost definitely toast, er rather swiss cheese.

That BS drain system is the 2nd worst thing they did when putting that engine together.
There's so much bad info and bad advise regarding maintenance on this engine.
