I have an 8hp....
Art, I have an '85 Nissan 8 HP on my Hunter '86 25.5 and it is GREAT....I just bought the boat in March 2001, and the previous owner had all of the paperwork with the boat, and he bought the Nissan 8, back in 1988....When I got the boat last year, the boat had sat in the marina for almost a year without any use(divorce sale). After I got the boat I changed the spark plug and changed the gas, and she started right up. I had to move the boat to my marina, 12 miles away, and wouldn't you know it, the fog was so thick you barely could see the bow from the cockpit. My son and I motored for almost two hours at about six knots, to the marina, and the Nissan never skipped a beat. It starts on the second or third pull every time (because it has to suck the fuel in the carb). I run it dry every time I use it. Great little motor. I( am well pleased....Good luck.
