Three questions... first, a marine battery comes with my boat when it’s put in the water later this month (no idea what kind or size marine battery... never bought one before), but if I wanted to buy a good second marine battery to have on-hand, what the heck do I buy? Brand, amps, size, etc.? Also, what wax do I use on my engine cowling and shaft? It needs to stay lowered in the water all the time as per marina rules and I thought a coating of wax or something would help me clean it easier. Do I wax the prop, too? As an aside, I’m also buying a cowling cover. Finally, do I need to scotchguard the playpen cover and Bimini immediately? Or are they already protected like the seats? Thanks.
