Great company right here. Purchased this for my Mercruiser 3.0, perfect fit, all parts needed were included, easy install. Absolutely love how it performed on my boat. Faster, smoother, quieter, but had a quality issue. Customer service did not hesitate in backing their product and immediately sending a replacement. Need more companies out there like these folks. 10/10 recommend

I was looking for a 15 tooth 14x21 pitch prop for my mercury outboard 300hp 4 stroke motor and this has been a perfect fit. It is very affordable and made well I feel it is a good quality part. I will give this a 5 star as it was easy to install and the motor runs smooth.

I'm used to stainless steel but if I'm not in underwater stumps, aluminum can work. I've always wanted to try a 4 blade prop so I'll give this 21x14 a try. Looks like a well made aluminum prop, but I'll stay away from the stumps.

I got this prop as a backup for my Mercury 200EFI. I had a stainless steel prop that is almost 30 years old so I wanted to get another prop that was a little newer. Also, I previously had a 25-pitch and this is a 21-pitch. My boat motor is getting older and with the added weight I have on my boat due to other mechanical upgrades, I needed something to get me out of the hole a little quicker. I received this prop quickly after ordering it and it came packed well in a box. It included the hardware needed to install it. And it was easy to install. You can see it installed in the first picture.The negative is that once installed, the prop was rubbing somewhere on my motor. I never could figure out exactly where it was rubbing but you could both hear it and feel it as I spun the prop freehand. Thinking it was rubbing on the outer diameter of the prop, I took it back off and measured the prop against my stainless steel prop. As you can see in the photos, my stainless steel prop is just shy of 4 inches outer diameter. As you can see in the other photo, the aluminum prop is 4.312 inches outer diameter. That is quite a difference. I did not want to use the prop when it was rubbing on my lower unit. So I ordered a couple of bushings to use between the prop and the lower unit. I extended it out just enough to minimize the rubbing. It wasn't completely gone but it was so negligible that I wasn't concerned. I then took it to the lake and tried it out. It worked great. My boat is much quicker on the hole shot. The motor seems to run smooth so there doesn't seem to be any vibration.Overall I am slightly satisfied. The prop works and I'm giving it 4 stars because of that fact. It would be 5 stars if they made it a little smaller in OD to eliminate the interference.
