[QUOTE="DaleH, post: 418938, member: 15636"] FWIW my 16' V-hull (16-degree deadrise) with full floor & raised bow deck, weighing an estimated 700-800 pounds before adding the OB motor would go 30mph when it wore a 40hp Merc. I upgraded to a 60hp Johnson and theoretically it should push me to 40mph, but I have opted to run a Turning Point 4-blade 17" pitch prop that will carry a load of std gear (that's [u]always on the boat[/u]) and up to 5 people, without lugging. With me alone she'll go 36mph, so I have no doubts she'd be up to 40hp if I had the right pitch prop (19" pitch per Turning Point's prop calculator - see here: https://forum.tinboats.net/viewtopic.php?f=4&t=37433) for just me or 2 people and the typical gear. Can't say you'll need to change your prop or not, but I too think that getting to 35mph WOT with the 50hp OB is doable. [/QUOTE]
