Nice looking prop but it won't slide on the shaft all the way. I am going to have to hone out the bushing a bit to get it to work. Other than that nice product and very quick delivery to my house.

This 7.8x7 prop is one size smaller than.the recommend 7.8x8 for my Mercury 4stroke. This is a perfect fit on my HEAVY , overloaded jonboat. The smaller size helped bring my r.p.m.s back up to an acceptable range. A very well made product ,supplied in a timely manner. James W.

well built prop and performs like it is suppose to.
Propeller reviewed on Aug 2nd, 2017
Had to re-machine the prop's bore to fit the shaft on my outboard motor. Was tapered from +.008 " diameter on both ends to -.004" diameter at center. My e-mail to Iboat's service department got no response at all. I won't bother trying again.

Great match for an old 14' lund and light load using a 30HP Mercury 4-stroke.

we work on a shallow river and go through a lot of props. iBoats has the best deal on them.
Propeller reviewed on Jun 11th, 2017
Prop delivered was 9.9 inch diameter by 11 inch pitch. Close but not what I ordered. Was stated to be factory replacement but isn't. It is just a bit slower but it will have to do as a back-up.

The prop fit my 30hp Mariner perfectly.

After too many logs and rocks over the years it was time to replace my prop. This was an oem part, so no surprises. My motor runs like it did when I first purchased it.
