Re: Trims Tabs
Hydraulic trim tabs are real nice on a stern-heavy boat or underpowered boats, such as an I/O. They were great on my 18' SeaRay/Mercruiser They are less useful on an OB powered boat, like my 21 Seaswirl with OB power, but still useful. My 21 footer is kinda nose heavy, compared to the SR, hence the less need for them.
I used them mostly for rough days in the ocean. Drop the tabs down and you can back off the throttle and go slower, still staying on plane. Makes for a smoother ride. Also helps plane the boat with 8 people or less people and someone on skiis or a tube.
