Picked up a 1987 Blue Fin Sportsman 17’. Still researching but seems to be a Fish/Ski type model. Side console, walk through split windshield. Coast Guard plate is pretty beat but says 100hp max. Currently it has an 85hp Force of same era. My interest is entirely simple convenient fishing on modest size lakes. Considering repowering with a modern efi 4 stroke. Any ideas on what a minimal/modest HP would work well on such a hull? 25-30hp totally under powering? I am not the least bit concerned about going fast, simply want something that will keep the boat manageable and making headway if I get caught in the not unusual 2-3’ white caps and strong wind. Bit uncertain on basic hull weight, current motor is about 250 lbs. and a total guess by the way the whole package feels behind my truck I place the hull to be around 650-700 lbs.
