Sea Scooters: Specifications
The Tapered HDPE Versions (illustrated right) are 1 3/8 inch
- Speed: Nearly 200 feet per minute
On all versions of the scooter, the motor seal becomes at risk
beyond about 550 feet, the bodies are subject to bowing at 700 feet
and crushing at about 1100 feet.
In both the HDPE and PVC (nose and tail material) versions, the
flex will become an issue in the 900 foot range, which becomes a
moot point due to the risk to the seal and the chance of leaking
around the o-rings if the body flexes (a major issue at all depths
with HDPE bodies, which we do not use for that reason).
Between 450 and 650 feet, the flex in the PVC bodies is between
5/100 and 8/100 of an inch.
Both styles and all sizes come
with rewound motors,
the same motors we use in the WKPP

On all versions of our scooter, the motor seal becomes at risk
beyond at about 550 feet, the bodies are subject to bowing at 700

the 900-foot range, which becomes a moot point due to the risk to
the seal and the chance of leaking around the o-rings if the body
flexes. This is a major issue at all depths with HDPE bodies, which
is why we do not use it. Between 450 and 650 feet, the flex in the
PVC bodies is between 5/100 and 8/100 of an inch. Contact
