I'm doing my Bellows. Mercruiser A1G1. Are the Amazon Bellows Kits any good?

Has anyone used Amazon Bellows Kits? If so did they hold up. Just getting some ideas before I purchase a Bellows Kit. I'm probably only going to need the Bellows is all. My Gimball Bearing and all the other parts are fine. Just curious to know if the actual Bellows are halfway decent. Thanks

Amazon..................DOES NOT ............specify the quality of anything.
I have caught Home Depot selling a famous brand name item and model with derated quality. Just 1 letter or number in the original model number states a......ANYTHING.... goes. All part of big businesses doing HUGE volumes.

Amazon is fine so long as it's an actual Merc dealer using Amazon.,, can also be Sierra otherwise it's a crap shoot

FYI, my brand new OEM Mercruiser Bravo3 U joint Bellows that cost me like $140 is Made in China. So if Mercruiser Corp Purchasing/Quality Depts can find a worthy Chinese vendor, maybe you will too??? Point being made in China is not automatic disqualification.

Interesting, thanks.

Nope,..... But I once used a Sierra bellows kit on my ole Alpha 1,.....
After 5 or 6 years, it didn't leak, but was Extremely bloated, so I changed it out for a Merc / Quicksilver kit, which is still on that transom assembly,....

Get an oem merc. They last a long time. My original ones on my 2004 boat were changed at 18 years and still not leaking

the off-brand chinesium bellows kits are a crapshoot.... I put one in, and it lasted about a year and a half.... OEM will last usually 3-4x that. Sure you should be inspecting every year, but they arent cheap enough nor fun enough to do more than you have to.... and having one go out mid season is even less fun.... Unless you are using it to prove the hull/engine/drive and are on a strict budget, avoid and use Sierra or Genuine Mercruiser....

the gimbal bearings in those kits are pure unadulterated JUNK.... The one in my kit had metallic debris from machining in the outer aluminum ring.... DO NOT USE THESE without a GOOD inspection....

FYI the first 2 of 3 new Mercruiser OEM gimbal bearings (Made in Italy) ordered this May and produced in separate lots late last year had same machining debris. 3rd one had no debris but I could not articulate the gimbal function using alignment bar. Hoping it will bust free under force of engine and is not a mfg defect.
