Problem with rib starting

Jwmarineuk · 04 October 2013, 20:52

Took rib down to the slip today for the first time.

It's a 2006 2 stroke 75 merc. The engine was running fine on hose and we thought we'd run it up on the trailer before launching.

Anyway it was difficult to start her up. But eventually got it going. Killed the engine to drop it off the trailer, then it wouldn't start again??

There was no sound of the solenoid clicking or the starter even trying to turn over.

Checked kill cord etc, battery voltage was 12.16v. Quite low by this point but bilge pump was still working and tilt/trim.

Any ideas? Blown fuse?

Could be inline fuse. On my Tohatsu 60C its a 20 amp glass fuse, (rubber plug) located next to solenoids near remote wiring loom.

Battery got plenty juice? Should be anywhere between 12.7-13.4v on full charge.

Check condition of wiring from battery to engine, including terminal connections. A multimeter is invaluable for continuity test.

Just reminded me - if you've continually tried to turn the engine over before (prior to launch) you could have damaged the starter motor. Again rule this out with multimeter, or strip out starter motor and hook it up to the battery.

Putting battery on charge over night and will get down to marina again tomorrow to give it a go again!

I understand to 2 stroke cycle, it was more that the starter stopped working altogether and didn't even try to start!

I'll get my multimeter on it tomorrow as it
Could be an ignition fault?

The wiring is pretty bad at the helm end, all corroded, thinking its a bad earth maybe or if negative wire is bad it might cause the fault?

Just a thought it's not in gear is it?

Might want to sort the above out before you try to launch again, head out to sea and find you need rescuing .....................

Yeah wasn't going to launch it fully just dropping on the slip at was going to run it up on a rope, safety first!

Have left the rib with a local marina now as I'm away for four months now!
