going to look at a 253 convincor with a 454 mag efi in it tomorrow. and was wondering what they are known for having wrong with them. any help would be great thanks.
That is a well built boat theirs nothing I herd of being problem spots. The only thing that you have to worry about is how the previous owners took care of it. 500 hours on a engine in a boat that size means the engine is very tired and it wont be long before it needs a rebuild. If it was used in salt water find another boat it wont be nothing but problems.
Their is no reson that boat cant still look new if it was taken care of
