We just moved down by the bay and the guy left a 1988 Shamrock 20ft with the house. The boat runs good but it doenst idle and it keeps over heating. Its got a 302 ford/pleasurecraft in it. Its a great boat but we keep having little problems with it. What temp T-stat do you guys run? What temp should this engine be running at? Were good until we get around 2500 rpms than we start having trouble. <br />Chris
