i was running 27 tempest but felt it was giving to much lift hardly no trim. ran 28 bravo today ran very smooth great hole shot but still walking at 70mph didnt feel i was getting enough rpm. could the problem with the walking be the factory installed 6″ slidemaster was anybody had this issue and gone to bigger fixed plate with any luck. i fish lake michigan i dont need 80mph but feel i should be able to run 75 stable. fury or trophy?, or 8″ plate?
I have 07 Puma with 250 ProXs and I run 26 Fury to 76mph with me and full load @ 6000rpm with right water conditions before I get any significant walking. I think your wheels are to big and your having to give too much trim trying to get Rpms up. Try the fury get trim between 1/4 and 1/2 you should be right with plate set about 1/4 up. Be sure and get to trim slowly. Lots of posts about that set up and about chinewalk in general check FAQ section. Seat Time cures most of that, the lower pitch bigger diameter I thing will help
I have tried numerous pitches in the Trophy, Tempest, Fury, and Bravo. I have found the Bravos to give the best all around performance. Bravos are designed to run about an inch higher that most applications. I would leave that 28P Bravo on and with the 6 inch slide master, start raising the motor in slow increments (1/4 inch at time). My inner plate is set about 3/4 of an inch higher than my outer plate. This is about 3/4 of an inch higher than set from the factory. At higher level, the Bravo has great hole shot, great grip in turns, loads easily, will break 80 with me fully loaded, and runs 20+ lbs on the water pressure. I had 4 extra PVS holes drilled to help hole shot. When weight is balance perfectly, I get zero chine walk up to 78; it feels like its on a rail. Things happen fast at speed, and Im recommend l vest and kill switch always, but especially when running a new or recently altered set-up. I run a 27 P in the summer for “break neck” holeshot/acceleration, and a 28P in the winter. I turn the 28P over 6000 rpm in the winter. These props are easy to turn and compare to Furys 1 size lower in rpms (27 Fury = 28 Bravo; 26 Fury =27 Bravo).You have a great prop in the 28P Bravo. It is well worth your time to experiment with motor height. You will be impressed!
one side of plate is about 1/8″ higher i tried to straighten it but could not must have been drill off center could this cause the chinewalking? i have been running bassboats for 15yrs seat time should not be issue
I have been hearing some good reviews on the Bravo 1xs prop.
Not meant to imply that you do not know how to drive a bassboat. I have been running Bullets for several years now over 90mph and if you look back at my initial threads I had real issues with side to side rocking in my Puma when I first got it (almost backed out of purchase). Got some tips here and re-learned to drive and now I love it. They do run different than a lot of other boats mostly from what I understand is a little flatter pad, translate to less trim. Im still realitively new in mine so get adivce from some of the more experienced guys on here
plumber, You may have been driving bass boats for decades, though how many BCB models have you driven? You only use a portion of the trim on a BCB and not the whole trim range. Stay under half trim and work your way up to that in small taps or bumps of the trim button. Other brands of boats you usually trim as far as you can and they then are still dragging the hull in the tail while lifting the rear. BCB models use a lot of air compaction for performance and not just water. You have to pack that air and hold it where it performs best. BCB
Basscat on all of these types of walking questions ………. Could worn motor mounts or other things be part of the problem too? I noticed suddenly my 12 was getting a little hard to handle the other day and found the problem to be a loose bolt on my sea star. Since the disaster Aaron Martens had Ive been paying a lot more attention to bolts, etc at the transom………
High CottonOf course! Steering play as in fluid requirements, play in the cylinder itself or bypass of fluids, loose motor mounts increase all the wear and make driving hard, any bolts that are loose, engine mounting bolt and other factors all could play into this. One of the most major factors we find is actual play in the yoke that drives the side steer on the steering cylinder itself. We would replace and find spacers to remove that play where the aluminum to aluminum plate to cylinder caps wears. You can remove those and tap the ends out replacing the bushing spacers. We used poly or nylon spacers and removed excess tolerances ourselves before.
i think i will start by going down in prop pitch.
