Here is my cover letter for a Raymarine ST2000 I returned for an out of warranty repair.
Board died. Only emits an alarm. Nothing smelled burnt. Don't think the smoke got out but what do I know.
Brushes in motor worn down to nubs.
Copper trace on compass eroded. Jumper wire soldered on while mid pacific, worked fine.
Ball screw worn. Mounting post has play. Rod end worn. All contribute to end play.
Cordset crimped at strain relief, resulting in broken sea talk (yellow wire) inside bundle. Cable shortened while underway to eliminate damaged portion. Worked fine.
Key buttons leak, sea water on pcb and inside case. Made a cover of waterproof sunbrella. Worked well but still had to remove pcb to rinse/dry/recoat with corrosion block a couple of times. came back to life each time.
the latest board fritz did not seem to be associated with an event. plugged it in one day and nada.
all in all a very good product with over 15 thousand nm bluewater, 20 thousand total.
Not sure what you can do with this but I thought I'd try.
Thank you for your time.
For the listed flat rate price of $300 I received a unit consisting of all new components save the lower case half and a used mounting pin, neither from my unit but serviceable (minor wear marks not affecting performance).
Total time from mailing to receipt was one month. Not in a hurry, boat is on the hard
With better waterproofing from Raymarine (button pad liberally sealed) and an improved sunbrella sock, I expect this unit to run until the motor brushes
Longest I ever used the unit was 31 days/24 hours a day coming back from Cabo San Lucas MX to SF via clipper route
. All in all very pleased with the product.
Biggest issue turned out to be the plug
and socket. The fit relies on a labyrinth to keep water
out of the socket. Doesn't have a watertight seal. After several days in salt
spray, all of the cockpit
surfaces are conductive. Current leaks
from the + to either the seatalk
wire induce an additive correction when using wind trim or gps
waypoint methods. Results in "accidental" jibes.
