- Mercury Spitfire 4-Blade Aluminum Propeller, 10.3” Diameter x 13” Pitch, Right Hand Rotation

The Mercury Spitfire 4-Blade Aluminum Propeller (10.3 x 13 Pitch) was a perfect upgrade for my 60HP Mercury EFI. Install took me about 10 minutes, and everything I needed was included—except for marine grease, which would’ve been a nice touch if they had tossed in a small tube. Still, that’s a minor gripe.Once installed, the difference was immediate. The prop dramatically improved my holeshot and got me on plane much faster than the stock 3-blade. It grips the water better, especially in tight turns and rougher conditions, and overall gave the boat a smoother and more controlled ride.Build quality is solid, and it feels like it’ll hold up well to regular use. For anyone looking to get more out of their mid-range outboard, this prop is a worthwhile upgrade. Highly recommended!

i have never wrote review before but the prop saved me couple thosunds dollers on buying a bigger motor. ranger 60 with 900 pd of people the boat would not get on plane that is 400 pound over what the boat is rated for put the stiker 4 blade on and plane out just fine gained 500 more rpm’s u can tell the difference right out of the gate and gained couple more mile per hour it runs faster with the four blade with 4 people than it did with the 3 blade with two people so if your having problems like that this prop will fix your issue

Last week I placed a new 2015 mercury 60hp efi on my Palm Beach fiberglass, deep V 16 ft cc: approximately 1000-1100 lbs, without me or engine, ....probably close to 1600 lbs overall. It had the new three bladed prop that pushed it to a GPS of 35mph, but took approximately 75 yards, and what felt like a minute to plane. I utilized the program at Mercury in every category, ie. fishing, performance, etc., and the 10.3 x 13 prop continually came up as a choice, so without a tach connected, as of now, I decided to purchase and see what it would do. With two people (340lbs?) and six gallons of fuel it literally pushed my hair back taking off. It continually planed in approximately 6-8 seconds with a top speed of GPS clocked 33mph. It appears that it has dropped a couple rpms, at wot and I might be able to change, but the engine doesn't struggle in any rpm range ie., ...slowing for wake and then taking off again. Yesterday I had my bud and his wife with me (approx 470lbs) and there was absolutely no performance drop...and a GPS 33mph. It came with everything needed to put it on, except grease of course, and took about two minutes to change it over. If you are in my boat's weight range, you won't be disappointed with the performance of this prop.

18ft Lowe roughneck 60hp 4 stroke. I swapped to this prop from my factory 3 blade hoping to gain hole shot without sacrificing too much speed. Wow. Gained 2mph top end. Hole shot is amazing. Boat plains almost instantly. Gained 400 rpm at wot. Boat will turn on a dime at any speed without prop blowout. Why is this not Mercury's factory prop? Great value and great performance!

This comes with all of the needed parts for installation, including the internal rubber hub, which fit perfectly.My previous propeller was pretty beaten up. By the real reason I switched it out was because my rubber hub was "spun" and initially I had ordered just a new hub, but it did not fit even though it was supposed to be for my motor (not from this seller). So I tried again and decided to upgrade my propeller in the process from A3 blade to a four blade. I was pleased that this actually came with the rubber hub and all the needed parts for a complete replacement and fit flawlessly.

Purchased this prop for my 2014 175txw with 60hp 4 stroke.. It fit great. Planes off much faster than the factory 3 blade. Lost some top end but I dont run wide open anyway so thats not really an issue for me. Shipping was faster than expected.. I recommend this prop.

Brings my 13" Boston Whaler Dauntless out of the hole like a rocket. But I also have a hydrofoil on the engine. Top end has no slow down at all, in fact the top speed is better. Great prop for my setup, If you find that you're not getting the same results, add a whale tail to your outboard.

I was having trouble getting my 16ft Carolina Skiff on plane if I had three people onboard. It has a 40 hp Mercury 4 Stroke motor which should have been more than enough power. I thought I would try this 4 blade Spitfire out.It was east to install, a DIY project for sure.I have yet to try it with 3 adults on board but with 2, it gets up on plane faster and has been working fine all summer in the bay.
