Re: 140 merc parts in Car Parts store?
Soo, no way u can get internal parts for the 140 merc at your local automotive store,like crank bearings, piston rings ,etc?
Yes, if you know exactly what you are looking for... All the internals are GM parts, with GM part numbers, so yeah they should be able to get them, but you are not going to be able to cross the 140 to a specific year/model of car or truck.
Napa and Car-Quest have marine catalogs, so they can look it up there, but you will most likely be paying a "marine" price. A machine shop would defiantly be able to break the engine down and crossreference over to less expensive auto parts, that are the same thing as the 140 part, without the "marine" up charge,,, if they are available.
If you can cross reference your marine parts to automotive parts (talking about engine internals) you most likely will save money. I replaced all the rocker arms on my 140 during rebuild and the marine price was something like $15 each, auto part was $2 each, exact same part.
Just be aware there are many automotive external engine parts that will fit and make the engine run, but they are not up to marine specifications, could will wear out easily or create a dangerous situation.
