OK Im going to ask ! If you dont know whats wrong with the motor why are you looking to replace it ? it might be a nothing job might be motor out job but untill you know whats wrong its all speculation !surley you'd be better off finding out first ?
Ask the guy in the shop to give you a list or summary of what is wrong with the engine, then post details up here.no other Yamaha engine bolts in. Fex Ex or some other service can ship an engine on a palette for a reasonable price
guys before i talked to you i was in a shop...and the guy said it would be better to find a motorcause just to open and find whats wrong is expensive enough.......
