1986 23.5ft Bayliner Ciera 350 Volvo Penta<br /><br />My above listed boat will overheat everytime i go full throttle (45mph) it will start to overheat pretty rapidly, about (40-90) seconds.<br /><br /> when i back off the throttle to about 1000-1500 rpms it will gradually get cooler and then maintain the proper temperature if i stay at this speed. <br /><br />Im just requesting info on what may be the cause and or solution to this dilemma i may have, any and all input on this topic would be considered a great help.<br /><br />Thank you

Replace the impeller.<br />You should have done this every (or at least every other) year.

Mine is an OMC but with mine I had exhaust leaking into the intake water below raw pump. worked great below 2100 over that exhaust blocks the water flow. <br /><br />Alex
