Bennetts Vs Kiekhaefer tabs...

Even with mine legthened I can only feel them making boat handle slightly different, it does drag my boat when they are buried BUT I could drive there and boat wouldn't trip on a wave or anything real crazy. On the other hand I have driven a boat about the size of mine with the giant race ones, holy SHIIT, with them buried it felt like the boat was going to bury the bow and go under water and if they weren't even it was dangerous to drive , my guess would be they put some pretty big tabs on that boat to make it act longer/run stable and it is critical to have the tabs in the right position, Smitty

Huge difference. I've run single ram Bennett's, dual ram Bennett Sport tabs and Kiekhaefer all on the same hull.
I exploded a ram on the single Bennetts, upgraded to dual ram sport Tabs and exploded one of them (both while running in conditions way beyond their design limitations) and now to the Kiekhaefers.
I liked and was used to the action/reaction of the Bennetts way better. I could bury them and keep the boat on plane at 20 MPH's (30 MPH min planing speed w/o) in wicked conditions and run some down tab, up trim and the fly the boat through chop on the motors/tabs at speed. Large fun.
The Kiekhaefers are actually too big for this small of boat (24') and they're way fast. Keep in mind the Bennetts run off a single, tiny pump for both tabs where the Kiekhaefers have an individual pump (trim pump from a freagin I/O!) for each one.
Mine are so fast in my boat that if you just tap the button they free wheel past the happy spot almost every time.
I know people that won't even use their tabs because they're scared of them. Hold the button until the boats where you want it and it's too late.

I was under the impression that SV43 was a guy from the Outerlimits and this is what he said on page 1:
"Everone is fine. I am sure this post will have many storys, but only one tru story. Indicator on tab did not show proper display (new L.E.D. type) Doesnt take much to go over with a fast single engine boat."

Run some heavier oil in them, that will slow the speed of the ram.

Upgraded to billet 24's on a fast single Checkmate, big difference ( and no more blowing the clamped-on oil lines off the dual instatrim rams at 90+ ) but tab adjustments needed to be made with care and in small increments, letting the boat's attitude adjust after each small bump of the switches.

It takes time to learn but there are boats like mine running over 90 mph with no tab indicators and these are driver's boat that require a lot of input via constant small changes in tab and trim when driving fast. Mine has been running on the Great Lakes for 7 years now and I have hit my fair share of rogue waves and freighter wakes and not flipped the boat. If these were test drivers pushing it to the limit in turns then I understand how it could happen but if a new design has already overturned at moderate speed then maybe they need to find out why before more of them end up in the hands of inexperienced boaters. JMO and excuse me for telling it like it is.

That is a valid-accurate point you made regarding the inexperienced boater, regardless of the earlier criticism, that is from a legal perspective. If you (manufacturer) knew a defect exist(s), then you put that product in the market place and it fails, and you knew it would fail from manufacturer testing then watch out. That is not applicable in this accident, but now it is known that a potential defect may exist, so hence the defect (potential defect) needs to be addressed.

OL makes a good product, they will get that tab issue rectified.

I agree. It is an interesting topic though. I'm still just saying that in a smaller single, which is where my experience lies, I wouldn't use tab indicators to dictate my tab use anymore than I would trim via the trim gauge. Now it might be nice to have an indicator to look at and see where the tabs are when you've tweaked them but I drive by the feel of the boat and, as said, it is in small increments of tab and trim. If you hold the switch until you feel the effect then it can get you in trouble. I'm also aware that K-planes are different.

It sounds to me like these guys were maybe just pushing the boat to it's "Outer" limits to see at what point it would spin or get ugly and they found that point! I hope that's what it was.

thank you, thats what I use to break.:party-smiley-004: I had seen a big different between my 280s and 380s on both boats 24, 28 running them.ART :cartman:

And it makes more sense if they were not running hard, because at speed you would definately feel the tab being off. I can't comment on this or any other boat, but I would never drive mine without working indicators. On my boat a small tab change makes a big difference, only need to tap the buttons to make normal adjustments.

I found that out, 1st test run last yr lol. we still had air in the steering too. so we only ran 30 to 40 while testing the 1st prop. overnite we got the air out, but with my high x I like the 380s, so we changed them the next week. my 24 loved them in the rough with the higher x too.:cartman:ART

Right about what? The fact that they need to find out what happened and rectify it? Umm...of course, not sure of your point.

Your statement in post #76 is "Gimme a break will ya? WTF do you know?" in response to thirdchild's post.

You further wrote in post #78 "Oh...thank goodness...I guess that slams the door shut on the OL29, thanks for saving the poor suckers that were going to purchase this machine."

Thirdchild was right in regards to his post that stated, "if a new design has already overturned at moderate speed then maybe they need to find out why before more of them end up in the hands of inexperienced boaters. JMO and excuse me for telling it like it is." You disagreed with this statement in your posts in #76 and #78. I find thirdchild's statement to be accurate.

I hope that clarifies any misunderstanding. I am not attacking you.
