150 HO G2 top speed prop?

Hey guys,

I am new to the evinrude world, as the forums. I purchased a G2 150 HO about 3 months back and so far love it. They outfitted me with a 17 pitch RX4 prop to being with. It holeshotted like crazy but only topped out at 42.

I tested a 19 pitch Viper, got into 45 mph with 2 others kn the boat but only got 56-5700 RPMs out of it trimmed up, and it was cavitating slightly.

Anyone have recommendations on a prop yhatll get me to 50 without compromising too much acceleration and hit the mac rpms?

Depending on your boat, its weight, and hull design, you may try a Raker HO to see if you get more speed but you may lose a bit of acceleration. There are adjustable exhaust holes that may help increase any loss of get up and go.

 

Propping is trial and error.

Often an Evinrude E-TEC G2 is mounted too low on a transom and its design allows it to run higher than other engines. You may want to experiment with raising the motor one or two (or more) holes first. It is also a trial and error procedure.
