Was out on the weekend, one of the engines temp gauges showed high... it was at 190-200deg or so, the other engine showed 160 or so. The gauge that was showing 190-200 flickered once and a while. No overheat buzzer came on.. does this boat have a overheat sensor/buzzer?
I will test the gauge this weekend and see if its working, if it is, I will pull the thermostat and replace, and put a new impeller into the engine pump.
I will leave the drive units impeller last, as it was replaced a year ago. And dont want to have to pull the boat out of the water.
Any other ideas? Is 190-200 hot for these engines if in fact its not the temp sender?
its a open water cooling system, in fresh water.
any comments or ideas are welcome.
Also... on a side note... how hard is it to sync the throttles on these old school engines? at WOT one engine thottle is about 1/2 inch away from each other to match revs, and one engine is 600rpm away from the other one at WOT. Is it just a matter of pulling the carb covers, and looking the the throttle plates and syncing them up with an adjustment on the cables?
