I was involved in a boat business for years (so I feel like I have some insights, albeit twisted
![Wink ;)](http://forums.sohc4.net/Smileys/default/wink.gif)
) and what I own now (and for the last 12 years) is a 17' BlueFin with an 85 HP Force (Chrysler). The hull is riveted aluminum and the Force engine is not considered "top end stuff". I intentionally avoided fiberglass because of maintenance. You chip it a little and could have a hidden mess spreading like rust under the surface until you do a time-consuming fiberglass repair job. Aluminum boats generally don't leak or take "must repair" damage with the same level of abuse as fiberglass. If you own fiberglass you will need to maintain it. The aluminum/rivets lose you speed but gain your confidence in maintenance. If you want the speed back, spend more and go welded aluminum. In terms of engines, I'm having good luck with an odd-ball brand (Force) but you may want to stick with one of the big names. If you're a mechanical tinkerer, who cares. Outboard boat engines are relatively simple. Stay away from I/O arrangements - they are also more maintenance (alignment issues and outdrive maintenance).
Consider something with a console and live well (even at 15 to 17 feet) - The console is something to hide behind when surf is up or the air is cold and the live well is great for fishing. Go look at Cabella's for ideas about what turns you on - floor space, trolling motor, live well, bait well, console, seating, etc. I have a fish finder (speed, water temp, odometer, etc.) and a 55lb thrust trolling motor. Those are extras I didn't need but love both. I've also bought new seats for it.
My goals may have been different than yours. #1 - I wanted as little maintenance as possible (I do lower end oil, winterize routine which is super simple and battery winter storage) #2 Good platform for fishing, joy riding and possibly skiing. My boat is a 1988 (I think) and it's probably not worth more than $1000-2000.
I bought the boat with no skeg (fin just below and in front of the propeller). As you can see in the picture the skeg is gone - you can also see the prop is taking damage (prop repairs/replacement are expensive). I bought a new lower unit (just the shell) with a good skeg. I'll get to it after the K6 engine comes out.
