Has anyone added or seen a second battery on a Sport 150? I have a 2004 Sport 150 and I am thinking of adding a second battery. If any has seen this or done this please let me know the details. Thank you in advance.

tydog,

I am a firm believer in (1) ONE, battery as long as your main engine has an emergency pull rope system.

The only other time I would recommend a second battery is if the boat has an electric trolling motor or of course, twin engines where each engine needs (1) battery each.

Two batteries cost twice as much and have twice as much upkeep.. Not worth it in my opinion.
If you need another battery, the best option is to put it in a battery box and somewhere out of the way. That includes the wires connected to the battery also.

Maybe someone with a Sport 150 that has a trolling motor can give you more specific details.

tydog,

A simpler option might be to take a portable power pack. I carry one on my larger boat that already has a built in house battery and a seperate engine battery.

The portable pack carries a 400 cranking amp capability and it's fairly easy to carry and store.

I thought about it a few times but, as mentioned in previous posts, there are too many problems w/ 2 battery's on a 15' Whaler

Less room

If I need two battery's to run all my equipt on a 15' Whaler, then there's no room what so ever on the boat for me, just for the equipt.

switch over and wiring

weight

I can pull start my engine

I have "Sea Tow" (cost of "Sea tow" per yr. is less than the cost, maint. set up, and life span expectation of the extra battery), the "Sea tow" pkg. includes all types of marine salvage inc. groundings, jump starts, fuel delivery, prop change, unlimited towing, etc... so for that cost alone, it makes it more valuable than an extra battery to me, "Sea tow" is $149 a year, to put in an extra battery (yourself) w/ proper set up and switches is probably going to cost you more than that. Like "Joe" said, it really works out best to keep 1 battery in that boat but, make sure that it is new ( I buy one about every other year), and is in good shape, (do not store on the garage floor in the winter, battery is charged up, and put inside the heated house on a work bench, after it has been cleaned.
