Hi Nautijohn,<br /><br />so I've decided to give your trim tabs a try. I have a 13' Avon Searider (ex-coastguard) rigid hull inflatable with a deep v running a 50 hp outboard. I will be using this in the Pacific Ocean to cross the channel to the islands. I accidentally purchased the trim tabs with the 30 lb actuators. My question is, should I be using the 30 lb or the 40 lb actuators? Whats difference will I experience with the 10 lbs between the two? Thanks.<br /><br />Boaster
