2005 chap with Volvo Penta GXi 5.0L engine.
The last outing we had, after a good while of no wake speed, i noticed my temp gauge creeping up to the 250 point. it never got that high, but it was hovering just below. I pulled up to the gas dock, and popped the cover, nothing seemed amiss, and there wasnt even a lot of heat coming off the engine, i could touch most exposed metal areas, and they were warm, but not as hot as i would have expected. I also checked for obstructions on the water intake on the lower unit and it was clean. I let it cool, and headed back in. In the no wake area it was warm, but the temp drops back to normal range once i got on plane. it went right back up, idling to the dock to load out.
the impeller is on its second year, and looked good when i checked it at the first of this season. I did notice some rusty (mayby muddy?) water coming out of it when i stopped to check the overheat issue. but replacing the seal should fix that right?
Ive been having a belt squeaking sound on the last couple of outings, and since the belt is new, i suspected it to be a bearing in a pulley, so i replaced the basic pulley, but the squeak didnt go away. After more investigating, i noticed a little play in the bearings of the circulation pump. I shot some silicone spray in there, just to make sure it wasnt dry.
somehow the square hole in the tensioner arm busted, and i suspect that it is the squeak issue as well so here is the order list so far
new impeller kit
new circulation pump
new tensioner arm assembly.
now, if you have made it this far, thank you. here is what i need help with.
what would my symptoms of overheating point too? should the list of stuff i am replacing repair this issue?
ive done the impeller before, and the tensioner seems pretty strait forward, but is there anything i should know about the circulation pump replacement?
use the paper gaskets it comes with or high temp RTV? both?
Thanks in advance for the knowledge!
