Last Sunday, had the engine temp. warning go off on me. Thought the intake was blocked, nope. Able to bring the temp. down to half way point if I backed off of throttle. Yesterday was able to get back down there and I put a new impeller and seal in on the seawater pump. 3 things the local boat mechanic told me-
1) check temp. sensor - can't be this, since I am getting linear movement when temp. rises when I was planed out, and then drops when I ease off throttle.
2) check impeller and replace if necessary - this is what I did yesterday (see pic of old one before I removed).
3) flush out oil cooler water intake, sometimes sand/muck can build up in this and cause engine temps to rise 10-15 degrees - this will be my next task when I get back down there. Usually I use the muffs on outboard before the season starts, but this time I did not... wondering if this could've also lead to the higher temps since when I normally perform this I get some sand/dirt to come out.
I also attached a picture of the dash gauges when planed out (disregard trim gauge as this is not working) and photos of the oil cooler which is located on the top/aft of engine. The yellow circles are the water hoses. Question - which to remove to flush out with garden hose or should I just use the muffs on outboard and call it a day?
Any other insight would be appreciated, cheers boaters!
