Mercury 100hp efi 4 stroke

Have a 2006 one of these on the boat i just bought.

Just wondering whats the situation if theres a fault?

On my Suzuki DF140 when i turned on the key i had 4 lights water temp, oil etc and an alarm sounded but with the Mercury there is nothing like this.

When a problem occurs heating,oil pressure etc what is the warning?

I have a 2006 Optimax and when I turn the ignition on there is an alarm, which stops when the engine fires up. Fault warnings come up in the small windows at the bottom of the gauges or if smartcraft is used, also shown on the chartplotter.

We have a 2007 115 EFi and get the same sounds as 250kts (we also have smartcraft gauges) - I can have a look in the hengine destruction manual tonight if that might help?

Smartcraft

If you have a Mercury or Mariner engine and install Navman(Northstar) instruments such as chartplotters or fishfinders, you can get a smartcraft cable that allows all of your instruments to "talk" to each other.

So for example, i can can get all the engine data displayed on my chartplotter if I want, together with a load of other parameters that the basic gauges are not capable of showing, including faults. It is a good way of setting all the alarms, which sounds as though yours are either not working or disabled. Your dealer/service agent should be able to plug in a laptop and run a diagonistic on it

Hi Ciaran

Sorry, I'm not sure I can help much on your specific problem. I just had a read through my manual which also covers the 100hp engine (riveting stuff, un-put-downable...) and it wasn't much help. If all is well you should get a single beep from the warning horn inside the engine, or if things aren't well you should get a series of beeps to indicate why it's unhappy. In your case you don't get any beeps at all though, and the only references to that in the manual are:-

Engine Runs Erratically
POSSIBLE CAUSES
Overheating - Warning horn not working.

and

Performance Loss
POSSIBLE CAUSES
Overheating - Warning horn not working.

So not much use at all really

Sorry I can't be much help, hopefully someone who actually knows a bit about mechanical things will be along shortly

Ian

Spoke to the previous owner of my boat.

He said that the 2 ways he would have the alarm sound when he turned the ignition was.

1.Lanyard switch in the off position, turn ignition and the alarm sounded

2. lanyard switch in on position,boat in gear, turn on ignition and alarm sounded.


looking at point number 1. does this sound correct, thought it would sound if lanyard switch was on also?

what is meant by these:

Engine Runs Erratically
POSSIBLE CAUSES
Overheating - Warning horn not working.

and

Performance Loss
POSSIBLE CAUSES
Overheating - Warning horn not working.


I went for sea trial and engine was grand. Up over 5000rpm for 20- 25mins and no issues.

On further investigation i got more info about fault alarm.

one dealer said

" I'm informed by our engineer that the F100 engines with Yamaha powerheads (which this almost certainly is) do not always give a beep when the ignition is switched on. There will be a beep under some fault conditions, such as those you mention"

The previous owner said he heard the alarm when

1. lanyard switch in off position, throttle in neutral and when key was turned to crank engine alarm or beep heard.

tried this. No beep on turning on ignition but with lanyard switch off and turned to crank the alarm sounded until i turned off key or turned lanyard switch on.

Some forum's ive read people who had no beep on turning key tried what i did as a self test and the exact same happened.

I found my manual which doesn't mention anything about a beep when key is turned it just said a horn will sound if a fault occurs.

This manual is different in that part to the manual that a mercury dealer sent me and to the one that ianhappy has.

I'd say by reading the manual, going by previous owner, engineers response and getting the horn to sound when i made a fault by having the lanyard switch off thats it ok.

cracking system , I love it sadly it only works with certain merc mariners and mercruisers and this engine isn't one of them. neither will this engine operate the smart gauges.

yet another good reason t upgrade to an opti

no beep from our 2001 merc 90 four stroke but from experience when the oil pump seal failed when the engine was 3 weeks old it makes a **** of a noise. Followed by the sound of tears dropping on the deck as the engine siezed and we had oil everywhere (except in the engine!) Neither of the two replacements we had beeped either from memory. Our suzooooki beeps though.

Phew, glad it's all working as it should. I think my attempt at helping just confused us all further
