If you have a Highfield dinghy, Hurley makes some nice trim tabs that work great. They also fold up and out of the way when not in use or trailering. I have the 310 Classic with a 20 HP Suzuki and if will jump right up on plane. WOT is a little scary so I knee down and hang on.
Highfield Trim Tabs
Highfield Trim Tabs are easily installed and very functional. Clever design tabs to UP to allow the tender to be tied down tabs.hurleymarine.com
i love these, we have them on our 310CL. I keep them in the neutral position but they help keep the boat level and planes at super low speeds
