I have a 6″ slidemaster jackplate, 25P Fury and a 4 Blade 25P turning point. Engine height is 4 1/8 inchs below pad. With equal loads (2 guys, light tackle, wells half full, half tanks of gas) I get: Fury – 68.8mph , 5,500rpm. Whole shot is 2 seconds, all rpm feels responsive but man it gets loose. Chimes pretty bad. The roaster tail is about or maybe a but under the high of the engine. 4 Blade – 70.1 mph , 5,480rpm. Whole shot is 1 second, rpm feels good but not as responsive as the Fury. Chimes a little but feel a lot more stable and easier to drive. Roaster tail is the same. I had this boat out in December and it ran 74.1mph with the same setup and the 4 blade. Guessing the cold air and light load really helped, wow. Some of my question are:Anyone have the same or similar setup? If so what are your numbers ?What should my engine height be ? What PSI should I be running on this Opti once I start to play? Should I even mess with it ? 70mph is a nice round number ! Thanks in advance !UPDATE:Raised the engine to 3.5″ below pad with the Fury 25P on it and had same hole shot and performance (68mph) and lost the chimewalk. Issue is I lost PSI at 8 trim. It will drop to 9PSI at full trim. I really feel this Fury is NOT the prop for speed on this boat and thinking maybe a 26P tempest is next on my list. Thoughts?

I had a 2005 Puma DC with Merc 225 Pro XS, and got my best performance from a 27″ Trophy 4-blade; yes a 27″ Trophy out-performed a 26″ Trophy and a 26″ Tempest. My best speeds were 74.7 mph GPS, and my engine height was set at 3.25 below pad. RPMs would run 5600-5700 on the Smart Craft.I miss that boat! It was a great performer and looked good with Candy Apple and Malibu Silver color scheme…Good luck with your set-up. As water and air temps rise, along with the humidity, you will loose some performance…Gary Hollander

Thanks for some feedback on this Gary. I have a feeling this 4 blade may be the answer but reading other guys numbers I feel like I could be missing something with only hitting 70mph (GPS) and 5500 RPM (smartcraft). Maybe I should be happy with that number?

I have an 08 Cougar FTD with a 250 running a 26 pitch Fury. I found speed by trimming all the way out and then bumping it down a little. trimmed all the way out it would run about 73.5, but when i bumped it down it would run 77.7 mph. These numbers are with 2 people and full loads. Still learning to drive it and hope to hit 80. My water pressure is about 20 at wide open throttle. I know it is a different hull and motor, but it is worth a shot. Trimming down really helped chine walk as well.

Waterboy, that is where I found my speed actually. When I started losing water pressure all I got was rooster tail. I ran out of lake a little but feel by dropping the engine to 3.75 ” below pad I may actually hit the best all around performance but realistically dont expect to hit 70mph. Ill test this setup on the coming weekend. I honestly feel I should have no uses with full load and 72-74mph in this hull and engine. Just need to find the right hight and wheel! Thanks for the advice and Ill try your suggestion a little more.
