Quicksilver Nemesis 4-Blade Aluminum Propeller - For Mercury and MerCruiser Engines

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.

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.

Works great as a general purpose propeller. Has good bottom end bite for pulling tubes and getting on plane quickly. Only downfall is losing a couple mph on top end. Highly recommend.

Made a big difference on my outboard. Built very nice. Easy to install.

2023 Tracker Classic XL (17') 50 4stroke Merc. It gets out of the hole better runs a little faster. I don't like how easy it is to ventilate, both in turns, and with little trim. The factory black max was better in that area, but this prop gets out of the hole a little better.

Great Product ..what do expect from Mercury Marine . So I listened to all the hype Look on uTube on the Prop also named Spitfire . It does what it intended to do faster acceleration and hole shot . I would estimate 20 % faster with 2 people and 30 % faster with 4 people . Plus it will hold a wake at 2500 RPM on our boat at 22mph . So when it gets rough its nice to be able to plane and think of the fuel savings . Our Boat with do 50 MPH with a 3 blade Enteria 19 inch at 4500 RPM buts its a $600 prop and this prop will out accelerate it . Top speed is 47MPH at 4750RPM 14x19 NEMESIS with this prop . But we just cruise and do wakeboard and pull tubes . We have a Crownline 21SS with a 4.3 TKS Mercrusier 190 HP motor for reference . Highly recommend this prop and Amazon has a great Price ! ..Also this prop is great for docking and getting in tight corners at a Marina or in cross wakes or loading your boat on your trailer because with the 4 Blades it tracks very true . If you get this prop ..do yourself a favor to make sure everyone is seated because this prop has a lot of bite .

This prop fit my 1999 Alpha One, Gen One, 5.7 liter Mercruiser out drive perfectly. (21’ SeaRay BR Select Boat). I replaced a 3 blade 19” prop with the 4 blade 19” and it operated as advertised. Much faster to get on plane with less bow rise…Better handling in rough water…Stays on plane at somewhat lower speed. I did not experience significant loss, if any, of top end speed and stayed within WOT RPM range. I’ve not tried the prop yanking skiers yet but with the way it has operated so far I believe it will get multiple skiers on slaloms up much easier. I really like this prop for the money.

This propeller has changed the game for our skiff (16 ft Carolina skiff). Before I had to have my passenger sit on the bow to have a chance to get on plane, and couldn’t get up if there was any chop. Now I can go 0-25 in no more than 10 seconds with even 3 people and gear in the boat running into the wind and chop. If you have a lower HP motor like me, or are struggling to get on plane, look no further.
