I installed a SST Hydrofoil on my 88 Spl on a 22' deckboat.<br />It seems to help with the planing at a lower speed. Around 3000-3500 rpm the front end comes down now. More so than without the hydrofoil.<br /><br />At 4000-wot the bow is glued to the water with it trimmed down.<br /><br />20 bucks well spent.
