Re: Where do I mount smart tabs SX?? HELP PLEASE!
Since I have a slightly heavier boat with a V-8, I bought the 80# tabs and mounted them at the end of the last boating season. I took the boat out once last year with the tabs in the mid position.
They really worked well to control the amount of porpoising and bow rise on acceleration. The improvement in slow speed (idle) handling was worth the price of admission all by itself.
However, it did seem like the tabs slowed my WOT speed down by about 2 mph on GPS (54 vs 56 mph.) I boat in salwater so the tides affect speeds by 2-4 mph

. In other words, its hard to know what your actual speed is even with a GPS. I guess I could come to a stop and measure my drift speed and then add or subtract that from my "total" speed but I digress

.
Since I was thinking that maybe I should've purchased the 60# tabs, I moved my tabs from the mid position (3) to the lightest position (1.) Top speed really didn't seem to improve but the porpoising is worse than the mid position. Still not near as bad as pre-Smart Tabs, though.
Today, I moved the tabs to position #2. Unfortunately, work will preclude me from trying them out for about two weeks.
Overall, I'm very happy with the Smart Tabs and highly recommend them.
