Typical

Single main
engine 012
Evinrude ETEC 175hp
engine has a 50 amp
charging sys. Image.
so I can not use a separate battery smart isolator BC the
Evinrude has a builtin isolator.
problem is the required (OME premade)cable
is only 16’ long which will only stretch to less than mid ship. I would prefer to have this house battery in bow
area so cable will need to be another 10’15’ minium depended on which side port would be the 15’.
Helm is on starboard side all
rigging is on star, ideally placing the battery on bows port side would be desired.
Before I decide where to mount this house battery I will
cruise around a bit elevalueate the lest listing it causes
Then mount inside a
battery box.
This bow mounted battery will be inside the
cabin, which means if the windows are closed I will be exposed
To toxic an flammable battery fumes.
How long can the battery vent tube be? Will this vent tube require a end piece similar to the
fuel tanks vent
Which blocks
water from entering tube from above? Or can the vent tube outside
hull just be bent or elbowed
Downward?

1.(extend an enlarge the diameter of cable) for the isolator. I was actuely thinking of making my own isolator
