Super sweet ride by the way . . . you gotta be excited to get that thing out on the water :cool: This one is not the biggest, fastest or newest boat I've owned but I think im gonna really enjoy it. Just a boat to go and enjoy without trying to entertain a crowd. Simple and manageable with no stress. :party-smiley-048: RR |
A decent jumper battery pack is not light and would need to be secured, I do always carry a set of extra long cables in case I can help out.

More homework. The Merc bulletin SB mentioned states 150 amp hours or 650 cca. We've now established that the 76 amp AGM battery is 600 cca. I can't remember my physics equations from school so amps, ohms, coulombs, watts and volts are a bit of mystery now. I figure a pair of the 600 cca's will do the job. They'll be fitted tomorrow morning.
Reading the label on the battery, I'd say they come from your West Coast. Tell me they're a pos battery if they are but it's the best I can readily get hold of here! Thanks for all the helpful input, greatly appreciated. Cheers, Jon. |

Fôund that bulletin you referred to and if amps are the same as amp hours, even the little 4 cyl 2.5 and 3.0 liter engines require 90 amp hours so there's no way a 496 would turn over! The electronics guy I'm dealing with supplied new batteries for my last boat and he checked his records, they were 76 amp AGM batteries. That was for Verados and I was told they needed pretty substantial power to start them. Never had a problem.
There must be a different measuring scale. This guy supplies batteries to most of the boats in the marina and he couldn't be that far off. Back in Australia we used CCA as the measure. Google, hello! Are you there? Damn it. :) |
