I'm not much into skiing/boarding, Think the trim tabs are necessary?
How much more performance does the H.O. give? Is it worth the money?
The HO was a 5000.00 upgrade and 50HP on my 24, with my boat I am glad I did it. It also came with a beefier outdrive as well. IMO the 21 and 496 mag is a great set up. Trim Tabs are worth it regardless of boarding or skiing, your boat has saddle bag tanks, more prone to uneven loads, tabs will help level it out. Also in chop you can trim the boat down and the outdrive up for a way better ride it willl take away the pounding or porpising. People that have never had tabs dont get it untill they put tabs on a boat, then they get it. I am looking at tabs right now for mine, should have done it from the get go.
