Best overall combination without getting silly on the money is, if you are typically running this by yourself, raise the motor so that the propshaft is about 1 1/2 - 2 inches below the "pad." Get some bondo and fill in the top two water inlets, so that your bottom holes will be sucking all the water, and not so much air. get a 14 x 22 or so "inline chopper" which is $150-$250 or so on ebay. if you are going to keep it as a side steer boat, move your battery slammed to the transom on the port side (since you are sitting on the starboard side). move your gas tanks slammed to the transom next to the battery. With the old inline 115, if built before 1982, this is a crankshaft rated motor, so maybe 105 hp at the prop, you will close to 60mph. The vector is a viper with a longer nose, and a little more weight toward the bow. You will have a blast with it. I don't think your 115 will swing a 14 x24 chopper but it may. If you are 140 pounds, and your boat is a lighter vector, it may. if so, you could see 63-65 mph pretty easily, especially if you get your pad good and straight, and sharp. Some of these boats hook up pretty well without much work, and others, you do a lot of work and don't get much benefit. My second Viper I ever bought had an old 1976 115 evinrude, no trim and tilt, with a 13 x20 ski prop, with the motor buried in the water and the pad had a nasty hook in it, and I could gps 59.6. When you consider that some guys have an old 140, with a pricey prop, and the motor jacked up, and are running 65mph, I think 59.6 was pretty good. If you are just having some fun, do the stuff above, that does not cost a lot, and the prop, and you will like it. If you want to pick up more top end, I can show you what to do to the pad to give you an easy 3-5 mph, as it did on the same viper that originally only did 59.6. ronny is my name 443 975 8469 thanks
