 Brian,I think mine are rated for 80 amps, they are the lighter ones.  I only draw 50a max for now.Hank

 I'm thinking I may want to go for these heavy duty contactors since I will probably be upgrading to more powerful motors in the future.  
Get a couple of these baby's  !

What kind of current are you running thru those ?

 Brian,I use 4 relays continuous  duty for 19 dollars each. My vertical thrusters and positioning thruster use reversing relays but they are not continues duty.Hank

 Hank,         Back to your relays,   are you referring to your solenoids or do you have actual reversing contactors to reverse your motors.  When I was down in your sub I did not notice any reversing contactors..  They would have to be wired with heavy gauge cable to handle the current.

 Brian, a picture is worth a thousand words, send us a picture and someone will have a clever solution. Hank

 Brian,I had something similar, but I had hose clips around the barbed fitting& just took the vinyl tubing off to fill.The current system I am building has a small oil reservoir with a fillingport & low level sensor in it.Alan

Alan,         The system I have now ( if you can call it a system)  is I stretch the top of the vinyl tubing with a screwdriver and then I cram a 1/4" copper tube in between the 1" barbed fitting and the vinyl tubing and slowly pour the mineral oil in, that way I get the oil all the way to the top of the tubing.

Brian,is the problem just that the air that the oil is wanting to displaceis apposing the oil going in. Maybe pour your oil into a smallerdispenser that you can set up to let the oil dribble, in then leaveit & come back in a while.Alan

 Brian,Cut the vinyl tubing in half and put a cheap plastic irrigation tee in it and thread a plug in.  Get a Tee with two barbed ends and one threaded end.I will look into the curtis controller adjustment.Hank

 Yes !  ,  You have a knack for simple solutions !     I don't see any adjustment on my Curtis controller for changing any output voltage howerver, unless it is inside, and I didn't see anyway to get inside.
Also have another issue,  I have my 1" vinyl  tubing which goes from my thru hulls to my motors, with a junction in between,  I have a hell of a time filling those things with mineral oil.  I was thinking maybe I could drill a hole directly into the vinyl tubing (3/8" ) so I could insert a tube to enable me to pour the mineral oil in there.  But I'm not sure the best way to plug the hole where it won't work itself out.  Any thoughts ?

 These new ones are basically relays ,  the old ones are these cumbersome switches that I'm having a hard time finding space for.   But I really don't want to spend money that's for sure !    
Also, thanks for the tip on loosening up the stainless ball valves Hank.

 Brian, I agree with Alan,  I am using 4 relays (golf cart style)  and it is perfect.Hank

 Brian,looks like an upgrade for the old ones.If it were me I would stay with the old ones till you get a chance to giveyour motors a thrashing. Unless they are cheap!Alan

Hi All,            Thinking about getting these reversing contactors for my motors.  And also remounting all my motor electronic for better access .

Now I have the old style switches which are really a pain to deal with.
