Lofrans Kobra windlass - replacement?

[homer]

Our windlass has died a death and I need a replacement. I see from the manual that the Kobra (as fitted) used to be supplied in two power versions; 700W and 1000W. Unfortunately, the manual does not say which was fitted originally. I see that the circuit breaker is 80A which implies it is the 700W version. Is there any other way of telling? Presumably, if I fitted a 1000W version (which seems to be the only one available now) I would have to replace the circuit breaker and, possibly, upsize all the cabling.
The alternative is to fit a different make/model and I would also be very interested in any recommendations.

1000 Watts at 12 Volt means 83 and a bit Ampere. So if your circuit breaker is 80 A then I'm positive your old winch is 700 Watts.
You could have a look at some of the alternatives like Quick to see if they have something that could fit the place you have. You could go up to 800 Watts.

I see you are a member of the MOA. You my get the best advise from fellow members with a similar boat. I have a Lofrans Kobra 1000 on my M346.

Would be surprised if it were a 700w - even if the breaker is apparently undersized. the more powerful one is the correct size for the boat and doubt that Moody would have fitted an undersize unit.

Kobra on offer at Marine Superstore for £800 currently. Not worth looking to change type at that price.

I would certainly go for a 1kw even if your existing is smaller. If buying you could purchase the unit with the size of gypsy you don't want. Then use the existing gypsy and you have the other size in case you want to change chain size another day.
Depending how old the existing unit is it may not be a straight swop. The earlier versions had the unit dropped in the deck then the motor attached from underneath. In the newer models the motor remains attached requiring a bigger hole through the deck so the complete unit is dropped in.
The wiring also changed. Sometimes they used a motor with 3 terminals. Other motors had 2 terminals. Each come supplied with a new relevant solenoid box.

Kobra should have 35mm sq cable and 100amp breaker. If you think the existing cable may be a touch under size, leave the 80 amp one in and see how you go. I have a feeling ours is an 80 amp breaker (100w Kobra) and works OK.
