Hull HP Rating

[chuckz]

I have a 15' 1987 Bayliner Capri Bowrider. I cannot find a capacity plate on the hull. Does anyone know the ratings for this hull? I've searched the Bayline site without sucess.<br /><br />Also, is seems this is the only year witha 15' boat. Were subsequent models described as 16'?<br /><br />I ask these questions because the boat has a Force 50 HP on it (35HP at the prop). It is slightly under powered. I procured a Force 85 HP (60 HP at the prop). I know that the 85 HP was routinely installed on the 16' boats and want to know if I would be exceeding the maximum HP rating for my hull by installing the 85HP.<br /><br />Of course the guy I got in from said no problem, but I have two teenage boys and would rather be safe than sorry.

Re: Hull HP Rating

The power loss between crank and propshaft is more like 15% than 15hp, Chuck. That means that your "50" is probably 43hp at the propshaft and the "85" more like 72hp.<br /><br />Since this is not an engine trouble question, I am moving it to Boats.
