Mercury Spitfire 4-Blade Aluminum Propeller Prop 9.3 x 11P 25-30HP 48-8M8026655

If you read the other reviews they did't do this product justice. If you are looking for more potential out of your motor this will do it. I have a 16.5' Polar Kraft with the ice breaker ribs. To say the least it is heavy! I just put a new 30HP 4 stroke Mercury on it. The prop that the dealer put on was pitched too high. They put a 9.25X12.5 prop on it. If I had 2 + me in the boat my top end speed was 18.5 MPH. Just Me in the boat was 22.5 MPH. I was thinking I under powered my boat at first, but just by changing the pitch by 1.5 degrees, and having 4 instead of 3 blades really changed how I felt about buying the 30HP. It did what everyone said. I got way more torque and 3.5 more MPH. Now the cruising speed at 1/2 throttle is the top end speed of the old prop. This will make a difference in the performance of your boat!!!!!

I have a 16 ft Starcraft with a 30 horse mercury. From the time I bought it I was disappointed with the lack of get up and go. The boat came with the standard black max 3 blade with a 9.3 pitch. I complained to the boat dealer about my issues and they had me try an 11 pitch.This did make a small but definite difference but it still took forever to get up on plane and I lost a bit of speed. Well after a little bit of research I found the Spitfire. I took a chance and ordered a spitfire with the original 9.3 pitch. It has made a huge difference. I get up on plane in half the time, don't big down in sharp turns and I have gained 6 to 8 mph!From what I have read these are very common issues with boat packages like mine. It amazes me that the Spitfire is not standard equipment.

I have a 25 hp Mercury and I was hoping for some power gains like others have stated in their reviews. The only difference I really notice between this and the three blade is handling in turns. It's a good quality prop for sure but just didn't live up to my more than likely un realistic expectations when it comes to performance.

Love this prop! Came wrapped up in so much bubble wrap i dont think it could have impregnated your mom but it has made my boat around 10 mph faster!

Direct replacement for my 2006 25hp Merc. 4 stroke. Huge improvement from stock prop. Installed on 14’ Livingston center console. From a dead stop to wide open throttle major improvement. Top end speed and rpm increased and total holding under load improved a lot. Would reccomend this prop 100% to anyone wanting to improve immediate throttle response. Excellent customer service. I live in Hawaii and received my package in 5 days. Will definitely buy again, MAHALOS !!

Not worth the money. I get better performance from the three blade prop.

Running this on a welded 1542 flat boat with a 25 EFI Merc. This prop is the ticket turning 5800 revs at WOT hitting 27-28 GPS. I tried the 9.5 pitch in this prop before getting this one and was hitting the rev limiter - my boat is light - all the testing performed by myself with a very light load in the boat. Holeshot is better than any other prop I’ve used.

Great improvement for my boat. Have a Alumacraft 145 with a Merc 25 HP. Gained around 5 MPH, and can stay on plane without maintaining full throttle. with my Sport 200 Hydrofoil I can have a lot of fun with my boat now. Turning is much better. can cut hard and still maintain most of my speed. With my 3 blade could not hit a plane with my live well full, now I can. Excelent replacement for your 25-30 HP Mercury.
