These parts work fine. We bought extra items so that our order would qualify for same day arrival because we needed them quickly. They ended up a day late which was a little aggravating but glad we got the parts.

Bought for my Mercury Outboard motor on my boat. The price is excellent and made it easier to get than running to a boat shop,
