2008 Cougar with Optimax Pro XS 250 with 26 Fury no plugs in holes… great take off and speeds before Talon install.. Now even after removing some weight and moving some forward it is a bit slower but with live wells full it is real bad.. wondering if just a move to a 25 Fury would fix that or is there anything I can do with this set up to make it better.. Det wiler All -in one Jackplate full down on take off.. any input? Water temps about 68 and air temp about 75… Motor is running fine no issues there.. Full gas and oil.. 4 Battery set up All yellow top Optimas.

I had the same issue with my 2012 Eyra and in my experience there are two things you can do. 1) Send your 26 Fury out for additional vent holes to be added. This modification does seem to help hole shot. 2) Buy a Bravo XS in 27 pitch and have additional pvs vent holes added. I guarantee this will substantially help your hole shot. Handling is way better, mid range lift is better, WOT is easier to drive however you will lose about 1-2 mph at WOT vs. the 26 Fury.Some say dropping pitch to a 25 Fury help or going to a Trophy may also work. In my experience for my Eyra those options did not work as well as what I mentioned above.Good luck to you and I hope this helps.

My Cougar has a really bad hole shot with both tanks full, live well full, and two people on board. And…I have no power poles. I have a 26 Fury. Its a bit better when I run my 26 Trophy Plus though. I dont worry about it, as I dont tournament fish, so I never have water in the well anyway.

With hydraulic plates you can raise the plate for a hole shot and lower it to achieve maximum performance. This is not really what they are for, though it is a benefit. The hole shot sufferage is from more rotating upper weight that prevents the nose from going down and cantilevers against the boat weight. The effect of poles is more than effected and as stated here before those are a fairly recent development. We are going to do more to address power poles in the future. To achieve more hole shot we would release more ventilation behind the blades and drill more holes. Increase size till hole shot desired is achieved and you can always go back and add PVS plug or smaller holes on a Mercury propeller. Of course we are often wonder going back to the older electric anchors. We took them off boats to save weight, and now power poles are being added that add more weight. Sometimes things are not as sensible as they were many years ago? Oh Well!Good luck with your hole shot and hope you get it better.

With 30 years mechanical experience.. and fairly handy with any tool BCB do you think I could drill a set of holes myself with little negative or no negative impact? If so does anyone have a picture where they are located? Maybe even hole size and location? Thanks.. I will try lifting the Jackplate this weekend a bit and see if I can counter that way as well just as a test.. Thanks again

Definitely lift the jackplate. If its too low, your holeshot will suffer. You will have to play with it. Once you get it where yoy need it, you will need to lower it only slightly or not at all. As long as it doesnt blow out excessively when it come out the hole and planes.

My buddy added two Talons with brackets and tilt mounts and experienced a similar loss of performance and struggle to get on plane on his Stratos. He was actually so frustrated that he considered getting rid of the poles. Someone at a tournament suggested adding one of those hydrofoils to his Yamaha, and while he has still lost a few mph off the top end, performance has otherwise returned to normal.2011 Sabre FTD w/ Mercury 150 Pro XS, Power Pole Sportsman 2s, Humminbird 898 w/ 360 and 858 at bow, 898 at ConsoleFor lots of BCB love, follow me on instagram: @professorbeard
