Through trial and error I found that this replacement belt was the perfect fit for my car. The durable material ENSURES that it lasts longer than other belts I've tried. It has worked seamlessly and keeps my car running smoothly..
Genuine Mercruiser and fits my MPI 350 Mag a little tighter than the -003 version. My old belt has gone out of its tension range as it has stretched over time. These belts tend to break over time due to water pump torque and I always have a spare belt and can now change the belt in 5 minutes or less.
Pros
Replace worn or damaged belts to maintain proper operation of belt driven engine systems.
