i've got a 2014 Tahoe Q5I with a Mercruiser 4.3L V-6 and i need a new engine. I've been quoted on a couple but i just think its more than i want to pay. I found a 2015 4.5L Mercruiser with Engine Serial Number 2A573536, Drive Serial 2A536978 and Transom Serial 2A526006. Is there a website, book or anything like that that i can make sure this motor will fit my 2014 Q5i?
Any help would be greatly appreciated.
Thanks
