I'm a 'new' Santana 22 owner. My boat is a pre-1972 model, has been on the hard since 1996. I live in Arizona so I'll be sailing at some of the local lakes but I'm also planning to take it to Mexico and California (it came with a trailer). I have a few questions that I would like some advice on, any tips would be appreciated.

1. Outboard - how much power do I need? 4 hp too small? Is 10 hp too much? I'd like to be able to rely on it if I'm in a pickle so I don't want anything too wimpy.

2. The self draining cockpit, I'm assuming, drains down into the through hulls right under them, is this correct? Mine are there but no pipe connecting the two and they are offset an inch or two. Any tips on re-piping that? I would like to avoid sinking the boat.

3. How do I know what my hull number is? There are no numbers on the transom where they should be if the boat was post 1972...

4. What is the best, cheapest source for epoxy for general repairs? Do I really need marine grade epoxy?

5. I'm repainting the bottom, sanding all the way to bare fiberglass. I will be using hard paint as the top coat, since the boat is trailered and I won't be in the water more than a week at a time maximum, with probably a month between outings. How should I prep the bottom for paint? Do I need an epoxy barrier layer? Seems like a lot of people say better safe than sorry but others have said with such little time in the water doing so would be a waste. If no barrier coat is needed do I need to prime the bare fiberglass after sanding?

Any recommendations appreciated, I'm quite budget sensitive, but I know this will take some cash and some time.
