Funny you should ask, I just got back trying a Raker 24. It ran 67.4 mph. Hot and humid not a good day to make hp. By myself and half a tank of gas the Raker was too much for my 250 SHO to spin 6000 rpm. I run a 23 pitch that came with "don't know what type" normally. I will try a 22 Raker later on.
What is the max rpm for your SHO ? Not too familiar with it. I'm still a 2 stroke man.( 200 saltwater series yamaha ) but just had a phase 3 kit installed. Propping it now but my next motor WILL be a sho. By the way, what hull you running?
A Raker on a Yamaha? May have to try that one. I am running a 23 pitch M Series Yamaha prop on my 250 SHO Blazer 2220 Fisherman with a 10" Altas Jackplate. She runs from 60-65 depending on load and condition. Best so far is a hair under 68.
The 24 has too much pitch. The raker is a great speed prop I just have to find the right pitch . I was half way up on the jack plate and almost trimmed out and it still didn't blow out. The best speed was at only 5300 rpm at 67.4 mph. I'm trying to find a 14.5x21 to try. Had to get a omc spacer machined for a spacer.
The propeller is for a friend, he had to bore out a OMC thrust washer to run it on his 250 VMAX. He has a 22' Path Finder Tunnel hull. He picked up over 5 mph over the Tempest he was running. The 24 Raker is too big for his setup also. I hope to find a 21 Raker at a reasonable price and get it tweeked. I will post what happens.
