Drive bellows is too small on one side. Had to order another kit and spend more money as I already installed most of the other parts.

I always use Quicksilver parts on my boat, especially the Bellows kits. They fit as expected and since I keep my boat in the water all year, I sleep good at night knowing that I have these Bellows on my boat and it will be floating when I get to the dock.

I made the mistake of purchasing a low cost "economy " kit of seals, bellows and components when I overhauled my MerCruiser Alpha One Gen 2 outdrive 2 years ago. This summer I open my engine compartment to find that it was full of water. When I examined the outdrive, I found that the Shift Boot had torn, allowing water to stream in through the transom. I also noticed cracks in the Exhaust and Drive Shaft Bellows. I was advised to purchase a Quicksilver kit which is OEM grade. Much more expensive but much higher quality and longevity. I also noticed a host of superior details over the inexpensive kit: The water transfer hose is molded to the correct shape to fit in the Bell Housing in the OEM level kit. The inexpensive kit's water hose is just a standard piece of hose that is more prone to collapsing. The hose clamp grounding straps on the OEM kit are riveted to the Bellows so that they cannot fall off during installation. The straps that come with the economy kit are separate and have a tendency to fall off during Bellow installation. This can effect the integrity of final joint strength especially as the glue will be compromised by repeated removal and install in attempting to get the straps to stay in place.You only have to have one premature failure using a inexpensive kit to justify the extra cost of the OEM level kit.My suggestion is to resist the urge to save money up front and invest in this better quality kit.
