2000 Sport Nautique
by Joseph from Ellicott City, Maryland on July 29, 2014
This is an exact replacement for the gas spring in the 2000 Sport Nautique dash glove box in front of the passenger seat and behind the windshield. It snaps right in and delivery was very fast.

Heavy Duty Gas Spring
by Ron from Nashotah, Wisconsin on October 09, 2012
Very good quality product. Seems like it will last a good deal longer than the SL11 series (Standard duty) that it's replacing.

Attwood Gas Springs
by Michael from Bethlehem, Pennsylvania on July 16, 2012
These items have always worked well for me in the past. I did have to replace the original set that I used after about 4 or 5 years. I would reccomend these to anyone looking for boat hatch supports.
