pull start an opti forget it it will not happen, i dont care how big and strong you are, also the battery has to be a minnimum of about105amp hr of which about 8 volts are required to power up the pcm and the ign side to start so if you have to have a good battery to start

Back to the original post. WHY WHY have you only 1 battery? 200hp engine fit a second battery and a change over switch. For safety if nothing else even if you have a jockey engine you won't regret it.

I actually have three batteries on board!
And a change over switch! Two in the console and one under one of the jockeys.
The boat is at my house and the other two were removed for charging, just left one for the trim when servicing the engine.

I was just throwing the possibility of being able to do this in an emergency out for discussion.

If uncle al has said NO then I think that's the answer!

I'm not quite sure what having a second battery has to do with safety. I can understand having a 2nd for convenience in case you are in a distant port and you have accidentally flattened your main battery (or its died from natural causes), but I wouldn't consider that a safety issue. Equally if you decide to cut your engine whilst afloat, then just because your engine won't start doesn't necessarily mean you are at risk (and you'd be asking for trouble if you'd cut the engine in rough seas). My car only has one battery. The only time it's battery has failed is whilst on the drive.

It would be interesting to know how many people have had battery failure whilst underway. I suspect most power failures would be wiring and corrosion related.

But you can get left in the situation of recharging a battery that isnt too old, thinking thats all it needs, only to find out too late and well off shore, that it has a fault and fairly quickly discharges, plus with 200Hp on board, I'd be certain to have a bit of space for a spare guy! .. AND notwithstanding the fact that IIRC an optimax is best rigged with two always anyway, a special just for the engine and a service one, alongside

Left the AIS on overnight in Alderney, house battery was slightly down in the morning, everything worked-just a low bat warning on the compass. No drama, engine batteries still ok, once underway the engines will charge the house battery. But it seems the battery didn't like running down and wouldn't take a charge so one by one my electronics went down on the way home.

Combining the batteries sorted the issue out, just a shame I didn't think of it till I was back on my berth

ECU needs about 6v to power up, We did modify some DFI engines for rope start, but we had to keep a small battery under the cowl for the ecu to work, It takes one hell of a good few pulls to get them going. So to answer the question, if your solenoid goes and you have battery power i would suggest get a screw driver hold it over the two posts on your start solenoid and fire it up that way!!! But yes in theory you can rope start if you have some battery power!.

Your car has only one battery yes but you can stand beside it and look like a muppet.
Maybe in the Channel Isles it would be ok but not much chance of the AA coming along up here. OK replace safety with self sufficiency.

Can I just point out that at the turn of this year, one of the dealers on the E-tec forum decided to test out this on a variety of etecs. The smaller ones have always been sold on the fact that they do not need a battery to start or run, and guess what - neither do the 3.3/4 litre models! The crank needs half a revolution and it's gone!

Another great reason to buy an Evinrude!

If you flick through the posts you should find the video links.
