Time for me to change out my transom bellows and shift cables. Any difference between the Merc. and Sierra products aside from pricing?

In short.....YES. I don't mind using Sierra parts on several items, but bellows is not one of them. The Sierra ones seem cheaper and I don't want to take a chance as a business on something that could potentially sink someones boat.
This is one part that I would spend the money on and buy Merc. I normally would not recommend buying from Merc., but this is one case.

Is replacing the bellows a pretty straight forward job? No special tools needed? Just remove the drives?

Thanks Eddie!

One of my oldest friends has been a marine mechanic for 40+ years and has experince with both and would never use anything but the Mercruiser bellows. His experience says the typical life expectancy is atleast 2-1

Buy the real stuff you cheapskate !!!

I have never needed any special tools, and I've replaced a couple on my boat.

I think it is pretty straightforward. Some people remove the Bellhousing to put on the U-joint bellow. Some do not. If you are replacing the Shift Cable Bellow you will HAVE to remove the bellhousing.

How long do the bellows usually last ? I have a 2000 with the Bravo 1 and wondering what to expect. The boat show 282 hours and don't appear to have ever been stored in the water.

Time to change if only for piece of mind.

huh?
