Features
    • 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.

Just got them on. One short ride during the hurricane. Waiting to get out again this week. Hopefully this was the answer.
Comment: I appreciate the wrench however what wasn’t discussed is the need to apply a torque wrench so the wrench becomes redundant to having the correct sockets anyway. Zach was great.

The 4x4 changed was a massive improvement

I have a 220 Sea Ray sundeck with a 3x3 22 pitch props, 5.0MPI and Bravo 3 outdrive. It was having trouble getting on plane quickly. Per Zach's recommendations, I upgraded to a 4x4 18p prop and the boat is like a different animal. It gets on plane quickly and has plenty of power in the mid band now.

Definitely notice the difference

Much quicker out of the hole and minimal sacrifice to top end!
Highly recommend the 4x4 set up!

Bravo 3 prop switch

I have a Sea Ray 240 Sundancer with a 5.0 engine and Mercruiser sterndrive. Really under powered for a cruiser. Factory props were 4x3/21 pitch but could not plane out when loaded. Switched to Mercruiser 4x3/20 pitch with little change. Called Hill and ordered Signature series 4x4/18 pitch and it changed the whole dynamic of the boat! Gets on plane loaded and only lost about 7mph on the top end at WOT. RPMs were perfect and throttle response impressive.
