[PSUBS-MAILIST] MK-101 Connectors

[Jon Wallace via Personal_Submersibles]

A male connector threaded directly into the housing shaft stub is going 
to suffer the same potential of broken pins depending upon handling.  
One clumsy move and you may have an unusable motor in the field so you'd 
have to carry some spare male connectors just in case.  Additionally, 
unless you have a configuration in which you can slide the motor into 
it's mounting and at the same time mate the male (motor) and female 
(hull) connectors you're going to end up with a pigtail or cable of some 
sort to make the electrical connection from motor to hull.  So I think 
you'd be better off with a female connector on the motor and a cable 
with two male connectors to make the electrical connection if a cable is 
required to make the electrical connection.

If SubConn could produce a two pin high power connector you could save 
penetrations by using a 4 pin female on the hull to feed two motors.  
This would require a custom cable but the K600 used a similar 
configuration for the original lights.

When we did our last minn-kota order the saltwater versions were the 
same price as the fresh water versions so there was no incentive to go 
with fresh even though they would work just as well.
