I have fished 16' deep aluminum boats for quite a while. River, bay, and on occasion the ocean. Be very careful of weather, especially in a 14' boat which is less forgiving. I would also stick to the river and bay in a 14'er. Be careful of weight trim, anchoring technique etc, The big boats will not always respect the fact that you are smaller with less freeboard so be proactive in avoiding dangerous situations with other boats.

Re the tune-up/impeller, the price seems reasonable and I would do it on an older motor with unknown maintenance history. A problem on the water can be expensive and dangerous. A little prevention is a good investment. A tin boat can be a fun and economical way to participate in local saltwater fishery.
