can i link two batteries together without risk?

Yes.
What are you trying to do?
What are your plans? I have plans to run duel batteries and capacitors. I will have a main battery and a back up, the capacitors are to run electronics like fish finders and a sound system, so that way there is less strain on a battery.
HUH?!?!?!?!
A Cap would only be useful as a buffer against a high sudden drain. Totally unneeded on a boat unless your running something like a BIG BIG amplifier on a radio that depands high current suddenly.
A Fishfinder draws very small amounts of power.

tks for all the input...my plan was just to have them linked so that I can have back up power as well I am planning on adding more lights (mood lighting...lol) and stereo with sub.....also, when i am putting my outdrive into travelling position it seems to really draw a lot (volt meter drops)....sorry brand new so bit of naieve
That's what I though but after first hand experience they allow long periods of power draw and no actual power drain from the batt. Had a cap power 3 12" subs for about 8 hours before it went dead. I also had a fish finder drain a batt dead in a days fishing, it was a brand new batt charged to full. Luckily I had a back up on the boat.
From what I thought a cap did which was for sudden power drains from a amp, acted like a second batt.
Huh!!!!!...first off, what do you think charges up the capacitor in the first place? Second, do you realize how big a capacitor you would need that would hold enough charge to power something drawing as little as a fishfinder for an hour?What are your plans?
