John Griviskis from Ship Shape TV interviews David Rose (Aftermarket Sales Director) from Bennett Marine on the SLT Self-Leveling Tabs. Get on plane faster and eliminate porpoising with easy installation. No pump or controls required.
What size would work for a crestliner 1750 superhawk? Actual length is 17' 9" and boat weight is only 2000lbs at it is an Aluminum deep V. Motor is a Merc 150 4 stroke OB. If 90lbs is too much force and it causes too much of a bow down attitude, is there an option to reduce the downforce?
Our Self-Leveling Tabs kits (SLT6 = up to 16’, SLT10 = 17' and up) will handle some of the basic running attitude situations of bow high, hole shot, slow speed plane, porpoising & limited listing issues (same side all the time), but we can't be sure they will work for your specific application. Normally, vessels above the 20' range will be better served by installing controllable trim tab systems vs. the SLT type (spring-loaded), since large vessels tend to need more trim tab control over their running attitude than spring type actuator maybe be able to provide. The best next step would be to call us at (954) 427-427 or email BMI_Info@Yamaha-Motor.com. Our techs would help you diagnose to determine what type of issues are you dealing with and trying to correct. Once properly diagnosed they would have specific recommendations. Thanks!
You & some other people caught that too, Bennett is a good co. but this is on the cheesy side, looking to make better royalties, what about backing down when tabs are in the full forced down position, effect on steering, water coming in from the stern ?
Will the SLT tabs work to level a load? Like on a small boat you're the only person in the boat, and it leans hard to the right, would installing the SLT tabs fix that?
Connor, Remotely adjustable Trim Tabs such as the BOLT electric system would be better for that. But if you install the SLTs and adjust them so one side has a little more downward force by using the holes in the tab where the actuator attaches, they would help.
I have a 17-foot Arima with 70HP 4-stroke engine and 8HP kicker and installed Bennett sport tabs. They worked great for about 4-5 seasons and then crapped out. One side works, when I switch the hydraulic fluid lines, the problem travels to the other tab...........so issue with hydraulic pump? I am interested in possibly replacing with the SLT units since this would be cheaper than replacing the pump. Any thoughts from Bennett would be appreciated.
