On my lewmar windlass there is a brake on the side. If I tighten it too much it won't operate. FYI I routinely lift 100' of chain and a 40 lb anchor.The electric windlass stalls when pulling up the anchor. W some manual help pulling up the chain it does begin turning again. However it shouldn't require intervention. It should be able to handle my 100' g4 chain and 30lbs delta anchor, no?
.......................... it's overloaded, way, way overloaded.It should be able to handle my 100' g4 chain and 30lbs delta anchor, no?
.......................... it's overloaded, way, way overloaded. If you look at the Lewmar calculations shown below, your Profish 1000 is only good for a working load of 26 lbs. while your ground tackle with 100 ft. of G4 and a 30 lb. anchor weighs in at 139 lbs....
Not sure where you got 26 pounds. You underlined 105. Keep in mind you're not lifting the entire chain rode, only that number of feet that the depth of the water is.
........................ and they call for a factor of safety of four. They state the working load limit of the Profish is 105 lbs. and that must be divided by a factor of four = 26 lbs. They also recommend using the total weight of the ground tackle because you never know when you'll be in deep enough water that you'll be lifting all of the tackle.Ron20324;1048421 Not sure where you got 26 pounds.

I just installed a 1000 last week, and the paperwork is on the boat, but a quick looking at the West book (page 219)explains in English that you MULTIPLY the working load in the shart TIMES 4 to get the pounds of PULL. That's why/how the ProFish 1000FF is rated, 1000 pounds of PULL. At 105 pounds of ground tackle (X 4 =420) even the 750 would be overkill, but all the same i used the 1000......................... and they call for a factor of safety of four.

As I said, their figures are very misleading and you have to read closely to ensure your choice is correct.
....................... it's clearer to use the Lewmar literature rather than the WM Advisor. Forget the maximum pull. This is the pulling force due to the locked rotor torque just as the circuit breaker opens. You never want to go there. Work only with the "working load limit".I just installed a 1000 last week, and the paperwork is on the boat, but a quick looking at the West book (page 219)explains in English that you MULTIPLY the working load in the shart TIMES 4 to get the pounds of PULL.

Please re-read and re-calculate your needs, and maybe you could have gotten by with something smaller than what you used.![]()
cymeyer;1048547... Did you have a windlass before or was this the first install?Wonder how hard it would be to put in a 321? Chris[/quote said:This was a replacement for an earier version of the 1000, which had a known design flaw. I don't know the layout of the 321, so can't really advise too much. Overall, it takes some advanced thinking about the task. The pic shows the original install, but the escond one i moved forward about 5 inches.
