Hi All,
I have a 2012 40 Hp Tiller Steer, that has been changed to Forward, or Remote Steer.

Mod E40DTLINM
Ser 05339834
Build 01/2012

The Boat is kept 250 KM away, and so I don,t Have instant access to it.

Basically, I have full Volts, from Battery to the Motor.
But the Motor will not turn Over. It is as if the Battery is almost Dead.
I have assumed, that it is a Earth Problem, but recently thought it might be the Wireing Loom connection, from the Key.

The Boat is a "Second Boat", and is rarely used.
I doubt it has done 150 hrs.

If somebody could give me some where to start looking, that would be apreciated.

TYIA
Jeff

If the battery shows only 12 volts it's dead

Sorry, it was 12.6 V I think.
The 90 HP, I have, turns over, and Starts, below 12 V, going by the Sounder.
I am confident, it is not the Battery, because that is the obvious item, to check first.
I took 1 of the Batteries, out of Boat number 1, thinking the same thing.

Any clicks on the motor when key turned to start?
Is fuel pump running when key turned on?

Start with voltage measurements on the 12v stud on the starter and the motor block while cranking.  Should measure within 2 V as measured on the battery directly while cranking.  No Less Than 10.5v cranking V on the starter stud while cranking.

Really need the E. service manual for your model #, has detailed wiring diagram of motor and external wiring.  Plus numerous detailed troubleshooting routines.

The fuel pump does not run at "key on" on inline engines.
"The motor will not turn over" is too vague to tell if the starter is energizing and trying to turn the engine.
Removing spark plugs to take away compression load could help.
I have also seen water pump impellers put too much load on the engine to turn over.

Thank you Steelhead and Rick.

I have not been down to the Boat, for 3 Months. (probably the longest time, in 15 Years).
We are hoping to go down in 8 Days.

The 12 V Stud, on the Starter, is where I checked, that I had full Battery Power, to the Motor, but I did not check the Power drop, while turning the Key.

From memory, there was a "click", while trying to start, but the fly wheel, would not move.

I guess it is possible, for the impeller to be stuck in position, because even though it is Winter down here, I live in Darwin, which is at the top of Australia, where we do not actually get Winter.

We have 2 Seasons. The Wet, and the Dry.
The Wet, is at Christmas Time, when the Temperature, ranges between about 25 Celsius at night, up to about 34 Celsius during the Day, and probably rains 4-5 days, out of 7.
The Dry, (we are nearing the end of now), the temperature range, is generally between 18 degree Celsius, at night, and 35 degree, during the day.

The Boat is kept Outside, and is possibly being cooked every day.

I have limited access to the Internet while there, but can usually do what I need to.

I will test your theories, and try and get back on here Next Week end.

Thanks again 


Jeff

Put a wrench on the flywheel nut and see if you can turn the flywheel nut clockwise.

Thanks for that olypopper, I had already decided that was the easiest way to check if the Impeller was stuck, and was the first item, on my list to check.

If the impeller is stuck, I will probably need to replace it straight away.

I am not totally useless, around Motors, but I am probably closer to useless, than an expert.

I have found the Fault.
The main Power Feed, between the Battery, and the Motor has corroded.
When I checked the Power before, there must have still been a small amount of Power getting through.
When I checked the Power, this time, I was getting basically nothing.
Looks like all I have to do, is Solder another Eye Terminal, to the Motor Feed, and a second smaller wire, that has also corroded through, at the same junction.

Thanks for your help Guys.
