Hello everyone ! I am trying to find out what the hp rating is for my son in laws 16 ft tri-hull .He has a 50 hp on there now but it seems underpowered . I have an 85 available and was wondering if that would be too big . The boat needs a full rebuild deck ,stringers ,and transom . We are just weighing our options . Thanks for any help !
