44348T Upper Exhaust Bellow 4" Tube Pipe for MerCruiser 4.3L 5.7L 7.4L V6 V8 Engines Sierra 18-2748

No complaints. Everything worked as advertised!

Seems to be as good as original part and fast availability.

The rubber components were pliable and fit well. The hose clamps were substandard quality and were too short to be engaged properly. Upon inspection I found that someone else had struggled with the clamps and had stretched the first few threads trying to get it on. The product came timely and was well packaged. I like to forgive and forget if I can, but the supplier needs to know that the clamps are not adequate. I have an alpha 1 gen 2. It could be that my mercruiser elbows are a little thicker than some other aftermarket elbows. Just adding a half inch to the clamp length would solve the problem. thanks

Thick and heavy duty. Nice hose clamps. Feels exactly like the OEM one I'm replacing that got old and stiff and crusty.

I have a vacuum/air system in my wood shop that has a large metal air intake. Unfortunately, I was having issues finding a connection that would stay on correctly when the air switches on and off with the CNC cutter. This slides over the connection point very snugly and has the provided hose clamps to help stop any shifting or movement. So far it has worked and has been the best solution I’ve tried.

The material was well shaped and seems sturdy enough to survive. I've got no issues with the fit and finish of the part. Nice to have a backup.They match the size of the existing bellows.

just as advertised and came quickly. seems sturdy and of high quality - will update this review if that changes

I got this for my classic 1988 OMC Cobra powerboat. It’s essentially a heavy-duty 4-inch diameter rubber sleeve with the worm-clamp rings you need to secure it. It was just right to replace the old upper exhaust bellows.
