trim tab question

appreciate the tips guys. unfortunately i have no pump to repair. i salvaged the tabs from a katrina boat that an angry track hoe operator destroyed when he was told he was fired for looting. i gave the yard dog 50 bucks and he said take what you can. i left with a 120 gallon aliminum gas tank, stainless marine bracket with platforms, 2 big surflo pumps, and trim tabs minus the pump and switch. the entire console (bout a 30' contender cc) was gone. so pump and switch didnt make it. i just wondering if the insta tabs are anywhere near the performance. tx
