IMO, the bigger the better when it comes to batteries. A standard deep cycle battery will be just fine for what you want to do. The 25hp outboard starter doesn't draw a bunch of current like an inboard so a dedicated "starting battery" isn't necessary. Buy the highest Ahr battery you can afford that will fit into the battery location. We sell Trojan batteries at the marina I work at and have good luck with them as long as they are maintained properly.
The combo start/deep cycle batteries are a compromise and I don't recommend them. Buy a large deep cycle instead.  |

Get the best one you can... Mine runs my electric start, trolling motor, interior lights, nav lights, bilge, etc. |
