Engine removal

[Cinken007]

How do you remove 6V53 Detroit Diesel engines from a 1990 Hatteras 40DC. Is there a best method since the mechanic company does not want to rebuild in place.

In pieces.

Short block goes out the saloon door with a long reaching fork.
Out the saloon window may work.
Both paths require a twist on the short block to get it out.

How bad was the damage requiring an out of boat rebuild?

Unless there is block damage there is really no reason other than laziness to remove detroit diesels from the boat for an overhaul. I would find a new mechanic before I went to that extra expense.

I thought 53 series was long gone by 1990 and yes unless you overheated and cracked a block there’s no reason to remove.

Most of the 53's went away by the the 1980's but for some reason the silver-series 6v53ti's carried on up to I am pretty sure 1999 or the early 2000's when new emissions regs killed it. They worked them up to 400+ horsepower. Not sure about the reliability getting that much power out of that small of a displacement, but it must be alright since I've never heard much bad about them. In any event, they were around then for sure.
