After 2 years in storage, I fired up my 1990 johnson 90 and after 5 minutes the overheat alarm sounded so i shut it down. A few hours later i tried to start it again but it wouldn't crank over at all. While running the water flow in the lower unit looked good initially then a little intermittent after the alarm sounded. Is this a tell tale sign of a bad water pump? Is this something i should try to can repair myself or should i pay for a boat mechanic?
