Took the boat out today for the first time since the virus lockdown opened up. Over winter I’ve replaced plugs, low pressure fuel filter and external fuel filter, drained VST but not changed HP filter, fitted new impeller and housing and had lower unit rebuilt and pressure tested at a local shop.
i haven’t changed T Stats. Water is coming out through telltale.
We went on a good run - 8miles offshore, fished the drift many times then thought I’d open her up to WOT for about 5 mins on our way back in. All fine no issues. Then we slowed down to idle to setup to drift local reefs and the overheat sensor went off (red light on throttle housing and continuous alarm). I switched of engine and check water inlet filters on outside of leg - both sides clear. Restarted engine and ran her at higher revs for a bit to get closer home - again no problem. Slowed down to hand line for mackerel and again at low Revs the overheat alarm went off. Switched engine off and Had a bite to eat before heading in as didn’t want to risk damage. Again as I’m trying to manoeuvre boat in the harbour the alarm went off.
The thing I don’t understand is the overheat alarm is only going off at idle not when I’m pushing faster - could this be caused by faulty T stats or something else? Help appreciated.
