I ordered the Antigravity one on Amazon last week and it is due in today. I will give it a quick review when it arrives, hope I won't have to use it but at least I will be prepared.

Hey one other questions for the guys using these to jump their twin engine boats, some of the descriptions say to remove the jump starter as soon as the engine starts, any concerns to leave it hooked up while u start second engine?

I have not tried it to start the twin engine boat, but I would assume with one engine going, there is enough juice flowing to crank the other one..

My Antigravity came in and it is getting its first charge. In the instructions, it says it will start a 4 or 6 cylinder motor about 20 times. The removal is recommended so you do not try to charge the pack through the jumper cables but I am sure it is ok for a few to get the other motor started if needed.

I did consider this but from what I have read, the alternators on these engines do not put out much juice, so am not sure if there would be enough to crank the other engine. If/when I get in the situation, I would just start both as quickly as possible and unhook the unit as soon as the second fires up. In researching the model descriptions on Amazon, it looks like some of the updated models have increased circuit protection. So maybe this is a non-issue now?
