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

Really excited to try this prop, very disappointed when it arrived. It had a small little nick out of one ear that made me suspicious that the deal was too good to be true. I’ve had it on my motor for a couple weeks now, the paint has already came off in the same place on all 4 ears. Makes me think that it is not factory paint. Also the motor sounds different, I had a black max prop on before, at first I thought it was just differences in prop styles but now I’m thinking that it is out of balance also.If you want a genuine prop, considerpaying a bit more to get something you are sure to be genuine.

My 25hp mercury always seemed like it wasn’t operating at its full potential and made getting on plane loaded a chore. I heard good things about the 4 blade props but was leery to spend the money.One day on the water I had to make a sharp turn to avoid a crazy jet skier and ended up banging up my prop on some submerged rocks. Since my prop needed replacement anyways I figure nows the time!Boy am I glad I did! Feels like a new boat. Much more holeshot and even gained top speed (went with a bit more aggressive pitch based on the prop selector tool) and getting on plane is a breeze even loaded down with tackle and two big guys.Worth every penny. If your thinking about it, do it. I’d recommend using mercury’s prop selector tool (google it) to find the right pitch for your goals.

It works well on my Regal 2150 LSC with a Modified 4.3 EFI (250HP). I get around 52MPH with this prop with 2 people on board (well, almost 3 since i'm 300lbs) and fully loaded of gear and fuel. Very pleased. Goes to plane with 7 people on board in about 15-20 seconds, which is reasonable. Goes to plane with 2 people on board in 3-4 seconds.

UPDATE: After 3 months of use I'm still very happy with the performance of these props, but I'm unhappy with the paint. Both have paint peeling, one severely, revealing abysmal surface prep underneath. Loss of one star. I did see a massive improvement in fuel economy (10L per hour!) but I'm not sure how much I can attribute this to the props as I also rebuilt the carburetors. I'm not going back to the 3 blades to verify!Just as the manufacturer claims these props delivered identical top speed performance as the 3 blade Black Max units they replace at the same size and pitch (14x19). They also deliver impressive hole shot power and low speed handling, which were my motivation in buying them. Time will tell if there additional fuel savings. My application is on an 8000 lb boat (loaded) with twin 5.7 Alphas. I am very happy with them.

New Quicksilver nemesis aluminium 14 x 19 RH to replace Solas stainless steel 14 x 21 on Regal lsc 2150 2003 with V8 5.0. Out of the box looks good. First ride feels good to. Easyer to get the boat to plane on water, motor feels very responsive. Will see if top and cruise speed still efficient on gas.
