Will Quicksilver oil filters 35-866340Q03 and 35-866340K be interchangeable for my 4.3 Merc v6 carbuerated engine ? The engine has the K filter and I just purchased a Q03 filter so Im confused ! Thanks Email donbradley3@gmail.com Thanks

Answer:

Both of those part numbers are basically the same item. The one with the K is a Mercury Brand item. The one with the Q is a Mercury Quicksilver Brand Item.

Their parts breakdowns are very good, but in my particular application, they were not all the correct part #s. Their pricing is very reasonable. Trying to get a real parts person to help you on the phone with the right part selections can take a while. All in all, I would definitely order from them again.

Problem fixed: Alernator belt broke and soon discovered that one bracket was broken and the other one cracked.

Lower alternator bracket failed and upper alternator bracket cracked which wrecked the alternator belt so battery couldn't charge and power steering was disabled. Crowley Marine had the only upper bracket I could find and provided it with a good price and free shipping.
