I know there is a button on the junction box, but is there a mechanical emergency stop mechanism on the KAD300's?

IIRC on the KAD32's there was an emergency stop near the injector pump, you pulled a small lever? (which I guess stopped fuel supply)
 
As far as I am aware, the button below the junction box is the emergency stop mechanism on a KAD300.
KAD32 has the lever near the pump.

What if, god forbid, there was a fire or the electrics melted?! I should probably go to bed, i'm thinking too much!
 
Shutting the fuel cocks will stop the engine after a delay.
And I suppose in theory, isolating the batteries and disconnecting the alternator would stop an EDC engine with a load of unhappy errors on restart, but I can't imagine trying to do this on a running engine.

Blocking the air intake might be a bit quicker if you can get to it.

If there was ever a fire in the engine bay the last thing i'd be doing is opening the engine hatch, though.

For safety, I want to introduce a system where I have an emergency mechanical pull-stop for the engines from somewhere within the cockpit, so I don't have to open up the engine hatch... is that even possible with these engines?

I'll need to try and find the solenoid that kills the engine, and maybe introduce a mechanical pull cable to that
 
If these engines have a rotary type inj pump with the fuel solenoid, then loss of electrical power will cut the fuel supply and stop the engine

volvopaul, where art thou? :D It's something i've always been paranoid of... if lost electrics, how do I kill engine?
 
Further to my previous post I have just checked on marineparts Europe and Item12 on the exploded parts list in link below is the stop solenoid

http://www.marinepartseurope.com/en/volvo-penta-explodedview-7738870-23-1973.aspx

This requires 12v for the magnet to energise, lift the piston against the spring. Therefore a loss of electrics will cause the magnet to be de energised and the piston will be pushed down by the spring shutting off the fuel stopping the engine.

Hope the helps and puts your mind at rest
 
talltim - Thank you very much for that link. Yes, it puts my mind at ease 99% knowing that if the worst ever happened, a loss of 12v to the solenoid would kill the engines.

The other 1% in me is thinking "If I got hit on the head and a guest needed to kill the engine, with no knowledge of turning the keys, how would they kill the engines"

To combat this, I would like to introduce 2 push buttons at the helm with something like "STOP" written on them. The idea here would be that when the buttons are pressed, the 12v is killed.

Has anyone ever done this before? If the power going to the solenoid is low current, an easy method would be to use 'push to break' switches, tieing in with the +ve feed that goes to the solenoid - would this make sense?

You would normally energise to stop on these, very easy to link a push switch into wiring at back of keyswitch to add an emergency stop
 
Well turning off the " breakers " in the electrical locker shroud kill 12v to the solenoids ?If you or crew cannot access the engine room?
On a more general safety note - i tend to brief my crew/ passengers before going out ( even in the SoF all dressed in high summer swimsuits etc)
I show them the ignition switches ,bow thruster and anchor controls at the helm .
Also show where life jackets ,flares and the Sat locator ,grab bag etc along with basic VHF chan 16 button .
I think most folks car owners can grasp ignition keys technology ?

A few y back we went to visit our appartment in Antibes via the boat ( quicker by boat than road in french school hols )
From La Nap .
Anchored in the bay off Salis beach - tendered in just wife and my self - left kids on board -nice calm in about 4-5 M with say 20-25m Chain out of 50m laid out .
Teenagers son was 14 daughter 12 .left on board
Off we went ,we got waylaid what was supposed take 1/2 h took longer -wind got up -off shore and boat started to drag into deeper water towards a Manguster 130 with crew -Son casually phoned us ( mum ) to explain this and I told him to start up ,bring the anchor up and move the boat .
Wife and I ran to the Ramparts in Antibes ( like an ancient sea wall ) and looked out to see it all unfold .
Son expertly averted our boat dragging down the side of the Manguster ,who started to " fender off"- and launch tender .
Thing is you need to make sure " crew" can cope if skipper is knocked out or like me temporarily not on board
I have even taught kids to stern too moor -in a fashion!
