    • The Signature FOUR by 4 is the ultimate combination of eight blades. Designed to work on the *Bravo 3 and *Yanmar ZT350-370 drives. These twin four blade propellers are so efficient they blow the competition out of the water.
    • The Signature Four By 4 Propellers were designed to be a direct replacement for the OEM three blade propellers. It may be necessary to drop pitch sizes when going to the four blade combination due to the efficiency of the extra blades. Generally, a decrease of 200 RPM’s is achieved when like pitches are installed. All mounting hardware remains the same with no additional hardware required.

5 of 5 4x4 stainless Mercruiser Prop July 24, 2020
Reviewer: Larry Elliott from Aberdeen, Idaho  
I asked the sales staff for a recommendation for a problem I was having with my Sea Ray 2005 Boat.  I had a problem that it struggled coming out of the hole  when fully loaded or pulling skiers or tubers.  The staff recommended a 4x4 20 pitch stainless.  I ordered the prop to come right after the 4th of July.  It arrived just like they said it would.  Our family put the prop to the test on Lake Cascade north of Boise, Idaho  The prop did even better than I had anticipated.  The boat seemed like a new boat.  It would come out of the hole great and handled wonderfully.  We are very happy with how the boat operates now.  Thanks Hill Marine,  you made our vacation great.

5 of 5 FOUR by 4 on Sport Cruiser June 9, 2020
Reviewer: Rodney Kranz from White Lake, Mi  
My Boat is a 2007 Sea Ray SD 310 Length OA 33' 4" Weight 14,000 lbs. Motors Twin Merc 5.0 MPI 260 hp each. Stock Props. 22P 3 blade WOT RPM 4300-4400, Speed 37 MPH Very slow out of hole and could not hold plan under 30 MPH. I went with FOUR by 4 with a 20P The difference is Amazing. I'm running 4900-5000 RPM which is the recommended max HP RPM for those motors. I gained 2.6 MPH on the top end and out of the hole is very fast. No need for trim tabs. The motors are running quieter, smoother and boat stays more level Port to Starboard. I can easily hold plane at 24 mph and it handles waves better because the props are holding the stern of the boat so well, you can feel it grip. The props basically checked all the boxes with this performance upgrade. I would not recommend going down in pitch unless you need to increase in RPM, for me that was needed. My motors are running with allot less stress and you can here the difference. This was a great improvement on my boat. Thank you!

5 of 5 4 by 4 Duo props for a bravo-3 June 12, 2019
Reviewer: Rick Curtis from peoria Arizona  
so I called Hill Marine and spoke with Joe, I explained to him what I was trying to accomplish to eliminate my 1999 Cobalt 230, with a 454 mpi. from hitting the rev-limiter when trimming the bow up too high. I've also put the corsa captains choice exhaust on it. Joe explained to me the difference of the duo 4 blades VS. the duo 3 blades. I needed to go up from my 3 blade 24 pitch to a 26, but based on what information he gathered from me he suggested I go with the 24 pitch 4bades, more hole shot thrust and less RPM on cruise speed. let me tell you.. I've been a boat owner for over 18 years and Joe nailed this. it's a rocket out of the hole, it holds the bow up, my friend is his boat said he has never seen that much of the bottom! on full throttle I gained 2 mph with 300 less RPM. I have to mention its easier to handle at low speeds and trailering.
BIG thanks to joe and Hill Marine... the only manufacturer of the duo 4blade, and they look as great as the picture!

5 of 5 380 Cruiser Yacht October 2, 2018
Reviewer: John Gaines from Ogden, UT  
Hi Joe.
I finally got to use the new props you sent me.  
Wow...   I jumped on plane in no time at all.    I was going through 30 mph in under 20 seconds.
I held plane at 24 mph.   Turning hard over was sharper and I didn't need to add power to stay on plane in the turn.
All this test was done with out using trim tabs.   All this great performance in a 20,000 lb boat.  
I couldn't hold plane with my old Merc props unless I was at 4000 rpm or more and 30 mph.  Even then it was work.
Every wave I hit, I would have to add power to maintain speed.
t took forever to plane out as well.   Without trim tabs, it wouldn't get on plane when the boat was loaded.
I also want to point out that I could get into my Engines RPM range with my Merc props. Even so, they still performed like crap. The engines sounded great with Hill props, like they were working less, and my fuel consumption was 20-25% less at similar speeds with the Merc props.

Thank you for all the help.  I should have done this years ago.   It's like a new boat.

5 of 5 Great Propellers!! June 11, 2013
Reviewer: Jonathan Richards from Tucson, AZ United States  
Hello, This is Jonathan Richards, we spoke via phone, and I ordered your 4X4 20p propset for my Bravo 3 350mpi powered 23 foot Tahoe deck boat. They replaced my 3 blade 22p. I bought these props I believe in February, and haven't tried them out till this last Sunday. WOW what a difference, I believe you nailed this one on the head! Great job. I'm sorry I haven't tried it till this last weekend. I am very happy, snappy, planes quick, very, very happy. I just wanted to type you a note to say thank you, And if I manage to ruin these, I'll be sure to buy the next ones from you!
