battery for evinrude 15hp push button? motorcycle battery?

[davidf68]

Would a motor cycle battery suffice for a push button start evinrude, as it costs a lot less than marine deep cycle ones, your opinions Would be gratefully received. And best dry box to keep it in?

Probably! I've run an old school two stroke off a 21Ah jump start pack battery with no issues for years.

Which unlike a certain battery in a Rib I know can presumably also be brought ashore at moment's notice to top it up from the mains in an emergency......

It started life in the box/case with the jump start pack which Brough a range of advantages but even then I bolted the engine connections so it wasn't a two second job to remove it. I recently rewired and ripped the battery out its case and it lives in my new diy jockey seat. It's a bit more awkward to get to than I'd like but I guess 20 minutes to replace it if required. It lives in a cliplock type box to provide some extra protection, because inside the jockey seat is not 100% dry.

Used to run a tractor/garden battery for starting my Honda 40. Replacement cost was about $40 US from a garden center.

Surprisingly, it started the motor while completely submerged (anchored up and diving in some pretty nasty swell. Came up to find about a foot and a half of water at the transom.)

You don't need anything special as a start battery any old car battery will do assuming it's not a big engine your starting
Deep cycle are intended for small draws over a long period running lights etc
A bike battery will do as long as it has the required output but I'd expect bike batteries to be expensive for there size
