Re: glastron 1977 v195 engine removal
I just pulled the engine out of my 1991 boat - 7.4L V8. Yours is a bit older, so I'm not sure what may be different.
Outdrive would have to come off. Then you got to disconnect every thing electrical and fuel related. It is best to take the battery(ies) out of the boat before you start disconnecting things. Often the engine hatch has to be removed to gain full access to the engine and be able to raise it out of the boat. One of the last things would be to loosen the engine mounts.
So, what do you have to raise the engine? Figure that a V8 is going to weigh 800 - 1000 lbs. You could use a chain hoist if you have something strong overhead. You could also use an engine hoist with the extender bar. You will need to raise the engine to about 8 feet to insure clearing the deck height. the lower you can get the boat, the less you have to raise the engine. I had to get my engine almost 8 feet in the air to clear things.
You will want an engine stand or some blocks to rest the engine on as you lower it to the ground.
I'm sure you will get more advice from others, but that's my experience to share.
