This boat is made by DreamBoat. When I baught it I was told that the ribbing had all been repaired. You can see evidence of the repair. I have two questions related to the boat. First it came with a non-functional outboard (85hp). It is rated for 80hp. what are my best options for repowering the skif? What hp should I be looking at for performance? Next, some fiberglass repair has been done to the bottom as well. It's all solid, what steps do I take to paint the hull and how do I repair superfisial cracks in the decking all around? Thanks for the help. It's my sons and my first boat. Cass

First off,a 70's boat with a 85hp 70's motor,you have work to do.Motors that were rated back in the 70's was rated at the cid,years later,around the mid 80's,the makers started rating the hp at the prop.Big difference!A over hp rated motor installed on a older boat is one of those things that should not be done,being it is ya'lls first boat.Some states that would be breaking the law.Painting the boat.You must dewax it,sand it,prime it and then paint it.

OK, So if the my boat is rated for 80hp in the mid 70's, what would be the equivalent modern hp be? What would a 1968 85hp evinrude be equal to today? I don't mind going lower on the hp. I would just like to get around, and maybe pull a kid in a tube.

The difference between prop and crank ratings depends on the individual motor, and in some the difference isn't that great. 10% if that. One thing to remember, a newer motor weighs a bunch more, so it may have a few more ponies, but that is offset by the additional weight. I can guarantee my 270 pound 125 horse 69 merc would be faster than a new 125 horse at twice the weight. That 68 85 horse would need to be replaced with something close to 100 horse to offset the increased weight if you are looking for similar performance. Since you don't know what the performance is, you will have to guess. Also, you need to look at your total weight capacity. If you stick a new heavy motor on that is the same power, your load carrying ability will drop due to the increased weight. The hull design plays a part in safety and handling as well. If it is a flat hull skiff, it will be less stable in hard turns and rough water than one with any kind of V (deadrise) to it. I would try to get the most power you can afford that allows a good compromise between safety, economy, capacity, and fun factor. Good luck....
