Nemesis

I replaced a 3 blade Volvo Penta prop with this 4 blade Nemesis, using the proper hub kit. My boat (a 2008 Glastron GT with a 5.0 GL) had a 19 pitch prop and it was over revving just a bit. I ended up using the 19 pitch Nemesis and it dropped about 200 rpm (which is what I was after). Better hole shot and plane speed. It's just a few MPH slower than the 3 blade. Over all, it's been great.

Make sure you get the hub kit for this prop sold separately! I own a 2001 Bayliner Capri 2150, a 3,000 lb 21 foot boat bow rider with a 5.0 L MerCruiser Alpha One stern drive with a 1.62 gear ratio lower unit. We like to take the kids tubing, so acceleration is important to me. I was currently running a quicksilver black diamond aluminum 15.5 inch three blade prop with a 19 inch pitch. We would typically load the boat with a 35 gallon tank of gas, 3 adults with 3 kids, food, cooler, and gear coming in with the gross weight of appoximately 4,361 lbs. When I was pulling a 3 person tube the bow would come up real high and take a minute to get on the plane. The boat would want to plane at about 23 miles an hour but my tube riders liked it closer to 20 miles an hour so i had to keep adjusting throttle to balance speed. My top speed was around 46 miles an hour. I switched to the nemesis 14“ x 19“ pitch 4 blade prop. Took it out today, and I was immediately satisfied with how it shot out of the hole! The acceleration felt good. It quickly climbed to top speed of 42 mph at 4.200 rpm when trimmed perfect. I backed it down and could maintain plane as low 16 mph! The bite the prop has gives me way more control and traction though the entire throttle only giving up 4 mph of top speed compared to the 3 blade prop. The recommended wide open throttle of my engine is 4,500 to 5,000 rpm max. So I feel like if I had a lighter load I may get that range, but today I was running a 4,000 lb gross weight with people and gear included. My max rpm was 4,200 rpm at 42 mph. Overall I’m super happy with the performance of this prop, definitely worth the upgrade! I hope this review helps.

I replaced the original 3 blade prop after doing a lot of research about the HP , pitch , diameter etc to be the best match for our boat pulling a wakeboard. This works great for out of the hole, you lose a little top end speed, but we didn't care since we're mostly running 20-25 MPH. Nice OEM prop.

Works awesome. Gets the pontoon on plane in no time and speed went up by a couple mph with no loss to rpm.

I upgraded from the stock 3-blade prop that came with the boat to gain a better holeshot and get on plane faster. This prop did both extremely well. As far as performance goes, the holeshot was amazing, it had much more dig and I was on plane 10 seconds faster than the old prop. I didn't sacrifice much in the way of top end, maybe 3-5 MPH, but I very rarely run wide open, so this was pretty much insignificant. The one word of caution I will offer is that this prop revs higher than the stock prop did. My Mercury Pro SX 115 is rated to 6300 rpms and when I trim to find the sweet spot, I could conceivably push past that. The one drawback for this prop on my setup is that the sweet spot for trim is very narrow and when you wander outside it, it's begins to porpoise. When it happens, I just trim back a bit. Overall though, I'm very happy with the purchase!

Was exactly what I needed for my Trophy fishing boat. The little diesel needs to keep its RPMs up to not overload when I have a lot of gear or people loaded up. Changed to this prop and it works great now. Lost a little top speed, but the engine is much happier. Seems well built and paint coating is good.

I had a Mercury Black Max 10.3x14 on my 60 EFI (17ft Tracker Grizzly) and boy was she slow to get on plane with two people and gear. I heard from some friends that this was THE prop for Mercury 60 on a 16-18 ft Jon boat. They were absolutely correct. The hole shot is much much better now and I'm on plane in about half the time. I only lost about 2 MPH top end at WOT, still runs 33 MPH which is plenty fast on the rivers near me. Low end handling is also much better, feels quite a bit more torquey at the docks when you have to make a tight maneuver. All in all, would buy again if something happens to it.

Works perfectly! Been in my Mercury 2002 50hp 2-stroke outboard for a couple of months. Improved low end but lost high end speed. Which is good for pulling tube on pontoon. It does come with a hub that was correct for my outboard.

Exactly as presented with exceptional delivery.

Unfortunately the was damaged when delivered, it was dropped over my tall garden gate

c'est un produit original (Mercury) et est arrivé a la date que Amazon avait dit.

Fits and works great on my alpha 1 stern drive

Fait parfaitement sur mon moteur Mercury
