Any ideas?

I'm getting an engine warning indicator on my Mercury Smartcraft gauge.

Was out for a run last week. Boat and engine ran well. Engine serviced just two weeks ago.
No problems during 3-4 hours out.
Back into the marina and as I was tootling around waiting for a space on the slipway to clear I noticed the engine warning light flashing on. No alarm sound. No loss of power.
I recovered the boat and headed home.

Only just now got a chance to go look at it again.
Turned on the ignition an yep there is the flashing warning indicating engine trouble.

I'm going to ring the company who serviced it in the morning and book her in again.
Just wondering if anyone else has come across the problem and any ideas what it might be?

Was it flashing a regular beat?

With older warning lamp systems the flash rate told you what it thought the problem was (e.g flashing once every x seconds was high temperature, double flash was low oil level - 100% on was "shut down asap" kind of thing)

Not sure about opti details tho', sorry. - does your manual say anything?

I had similar issue last year with my 1997 150 V6 two stroke. The oil warning light came on constantly we tried everything in the mechanical water and oil system no difference we then checked all the electrics and there was the problem bad connections. So check all your electrics wires and connectors. You never know.
Hope it helps

Are you sure at the service they reset the service interval warning system?

Thanks all for the suggestions.

Took it back this morning and plugged the computer in - seems it is a faulty water thermostat

Seems to be intermittent too. We managed to get teh fault to show up and then cleared it to check again. Would it show up again?

Anyway a new thermostat is now on order and the boat is laid up
I had been hoping to get out this weekend

OUCH!!!!



In pain after getting the problem fixed. Seems the thermostat was stuck open causing too much cooling of the engine.
Replacement thermostat, gaskets, springs, belt tensioner, belt and labour ---- £192!!

OUCH!


At least the boat is back on the water and going well.
Had a sporty trip from Kinnego Marina on Lough Neagh to Battery Harbour on the western shore of the Lough. Straight into a wind causing lots of white horses and water spray.

Trip back with a following wind and wave formation was great
