Contemplating buying one. No owner experience whatsoever with boats, other than family and friends. What should I look for? I'm thinking... Make them run it for a few miles full throttle. Make sure it doesn't miss. Ask them to turn it off and start and let it cool down and start again, making sure it starts quickly during both cycles. Make sure the water pump appears to be pushing sufficient water at idle and full throttle. Check for water leaking in the bottom once finished. Anyway to check for blow by on a 2 stroke? Anything else?
