Hi there, I have a 1986 Bayliner Capri 19.5 foot with a Volvo Penta aq125 and a volvo 270 outdrive. First off, I am new to boating this year so I am learning as I go, aka hoping for suggestions!<br /> Here is the problem, the boat starts up and runs fine once its in the water, usually at a temp of 170-180 degrees. Once on open water and the RPMs increase to above 2500 the temp rapidly (under 2 minutes) spikes to about 250 or until the RPMs are reduced. When idling or proceeding slow or moderately the temp remains just under 180, but under load or pulling a skier, (anything to go fast) increases the temp to dangerous levels. The wierd thing is the quick rate that the engine returns to a normal level if left idling or slowly proceeding . So????<br />I have eaten though an exhaust bellow, and initially thought this may be the problem...not so. (told you I was new), I do not have much help in the local marine store as they refuse to deal with Volvo- and treat the problems as an "see...they aren't good" instead of helpful suggestions. So I look to you. Those knuckleheads refused to replace my impeller!! I had to take it to a shop an hour away for this service. I had a new impeller installed, new engine bellow put on, new radiator cap, and all the oil changed. I have heard of air getting into the water intake tube from the outdrive.... does this make sense? Whats the easiest way to fix this? Please help me out!! Thanks-
