I am looking for information on how to evaluate what the maximum (and safe) outboard HP rating for a given boat should be. True, manufacturers typically have a plate affixed to the boat. I recently acquired a 1960's-something 14' fibreglass boat, but I can't read the plate markings. It has a 1975 Mercury 65 HP outboard motor, and it just flies!<br /><br />Does anyone have further information on this subject?<br /><br />Thanks.
