2000 Mobius V repair / service manual

Hello;

i was wondering if anybody knew of a repair or service manual for a mobius V boat. my engine block recently cracked and a new one needs to be installed. the local marine shop said that in order to remove the motor out of the boat, they need to cut away some fiberglass to do this. becuse of this they want to charge me extra labor for pulling the motor out and putting the new one in.

anybody heard of something like this? i just find it wierd that the engine can't be removed without cutting up the engine compartment to get it out.

needless to say i was hoping that a repair manual would have instructions on removing the motor without too much effort.

thanks!
