"Howdy,i have a 1985 260 weeke
"Howdy,i have a 1985 260 weekender with the 260 merc, eng runs good but when i run WOT 4500 rpm the temp guage climbs to just about the red,if i back off the power 300-400 rpm the needle drops right to halfway mark and will stay,drop it to idle and it goes below 1/2,only at WOT does it flirt with redzone,has new impeller,water feed hose,bellows.exhaust flappers all done this past winter by a merc repair shop,could it be a bad sending unit?eng runs strong,no oil/water mix,the port risor does run hotter than starboard at idle but otherwise if i did not look at guage i would not notice any problems,any direction i should go?
Thanx
