This is probably a dumb question, but will an old gray torque master gear case fit on a new pro xs four stroke 225 ( 2B738585 )? I wanted to ask before I put the old gear case up for sale. I also have another weird question, is it common to have 14+ hrs already on supposedly NEW engine. Just seems a little much. I could see 2-5, but not 14. Is there anywhere on the engine that will tell you what year it is? I was told I bought a 2021 mercury 225 pro Xs. Now im wondering if that what i really got.
