How fast has the Viper been? GPS speed?

[timw128]

The first Viper over 100 was back in the mid-70's. Sammy Naser of Action Marine, Dearborn Michigan, married a new mildly modified 1750XS to a new 15' Viper, with the windsheild on, at 107 mph on a Keller speedo. He did blow it over once, on the Detroit River, but he used it quite a bit. The name he painted on the deck sides was: "Mother's Worry".

I know this is an old thread. I just wanted to comment that Sammie was a friend of mine and he was responsible for popularizing the 'Streams here in Michigan. A friend of mine bought a VKing Comp from him with a special 2.4 6 carb OZ Merc from Oshkosh. I ran Vector Comp's with Baker modded pads and bottoms and Oshkosh 2.4 engines.
Sammie's mom had a fit over his Viper and the XS, hence the 'Mothers Worry'... here's a photo, although not the best. I have some more, somewhere, taken down at the Detroit River the day it flipped on him.
