my mercruiser 228 has developed an interesting problem ..... took boat in for tune up and servicing when i got the boat back it started overheating if i run it over 4000 rpm ........ took it in today to have it checked and they couldn't get it to overheat ....... put it back in the water and it's heating up again ..... the mechanic that worked on the boat has been in business for a long time and seems to know his stuff ...... any ideas ?
