Can I start my 14hp diesel boat engine with an emergency 12 volt pack (600amps i think?) if the battery is fla

Question

I bought quite a cheap starter pack from k mart. it is 12 volt, has jump leads and I think says 600 amps.

Can I start the 13 hp diesel boat engine with it, if the battery is flat, and what terminal do i connect (it says to only connect the positive ones)?

thanks

Answer 1

if its a 12 volt battery you can start it with a 12v jump pack.  connect black to black (negative) and red to red (positive).

some people connect the negative lead to a ground on the engine to avoid damage to electrical components, but i've jump started hundreds of cars and never seen this happen.

the correct order to hook it up is positive then negative,  and to unhook it is negative then positive.

Answer 2

It should do - that is a small engine.  If it is any interest I was once told that the reason you connect earth (black) to the engine is to go direct and to save one battery trying to charge the other - but I'm not convinced (though I still do it!).

Answer 3

I've never tried you particular jump pack, but I've attempted to start diesel sail boat engines many times.  Even with a large 500 AMP Charger, with boost capacity several times the 600amp claimed by your pack.  I still had to wait for the charger to run for several hours before the engine would crank.   I'd done this on Volvo's, Perkins, Westerbeke, and Yanmar engines.  So, I'm thinking the starter load is just to high, but I could be wrong.  P.S. I loaned a really nice charger to another mechanic.  He brought it back "fried" in just a few minutes.
