The manual leaves the V9 AC row (69000486) blank. Windlass holding load is 1,5 × max pull (as printed); higher loads through the windlass can cause breakages. Section 5.7 lists the V9 7:1 drive as 230 cc and the V12 as 13:1; the specification table gives 250 cc/rev and 13.5:1 (as printed).

Installation

Specify and install with a competent marine engineer. V9, V10 and V12 are extremely heavy: use a mechanical lift aid.
Confirm L/H or R/H chain alignment, a flat deck (pad out camber or sheer), space below deck for the motor/gearbox and cables, and that the handle can turn the drum through 360°.
On V9/10/12 the band brake operating position can be rotated in 30° steps.
Seal exposed core on sandwich decks. If using silicone-type sealant, let it cure before final tightening. Do not use a permanent adhesive/sealant such as 5200.

Model	Deck holes	Fixings	Max deck thickness
V8	13 mm stud holes; 150 mm and 115 mm cut-outs	Studs with Loctite 243; trim to deck + clamp plate + 2 nuts + 5 mm	76 mm (3")
V9	6 × 15 mm bolt holes; 178 mm and 140 mm cut-outs	Studs, deck backing plate, M14 nuts with Loctite 243 plus M14 Nyloc	150 mm
V10 / V12	6 × 17 mm bolt holes; 260 mm and 120 mm cut-outs	M16 bolts (not supplied), washer and nut with Loctite 243 plus M16 Nyloc	200 mm

Thread (A2-70 / A4-70)	Torque	Tolerance
M8	14.5 Nm	± 2.0 Nm
M10	30.0 Nm	± 3.0 Nm
M12	50.0 Nm	± 4.0 Nm
M14	79.0 Nm	± 4.0 Nm
M16	121.0 Nm	± 5.0 Nm

V8 under deck: 4 motor/gearbox positions; grease the shaft, check the drive key, slide the unit on and bolt up with Loctite 243.
V9 under deck: adaptor to the base with 8 × M10×55 bolts and M10 spring washers; coupling on the splined shaft with grub screw; motor/gearbox with 8 × M12×50 bolts. Hydraulic drive with brake needs no coupling.
V10/V12 under deck: motor/gearbox bolts to the base via a down tube. The motor/gearbox must not obstruct the chain fall hole.
V9, V10 and V12 electric motor/gearboxes need additional support under the motor.
Remote brake (optional): V8 cable kit (illustrated with 68000876), handwheel housing secured with M10 / 3/8" CSK bolts; V9/10/12 brake wheel UJ shaft tightened until the brake applies then backed off 3 full turns, stud through deck 20 mm (V9) / 24 mm (V10-12).

Electrical System

V8 2.5 kW 24V DC

Total cable run	Cable size
0 – 23 m / 0 – 75 ft	35 mm² (2 AWG)
23 – 34 m / 75 – 95 ft	50 mm² (1 AWG)
34 – 47 m / 95 – 119 ft	70 mm² (0 AWG)
47 – 64 m / 119 – 151 ft	95 mm² (2/0 AWG)

V8 3.5 kW 24V DC

Total cable run	Cable size
0 – 20 m / 0 – 76 ft	35 mm² (1 AWG)
20 – 27 m / 76 – 96 ft	50 mm² (0 AWG)
27 – 38 m / 96 – 122 ft	70 mm² (2/0 AWG)
38 – 52 m / 122 – 154 ft	95 mm² (3/0 AWG)
52 – 66 m / 154 – 193 ft	120 mm² (4/0 AWG)

Cable length is the total run from the battery along the cable route. Voltage drop must not exceed 10%; use type III stranded tinned copper with copper crimp terminals.
Fit the supplied circuit breaker close to the battery, dry and accessible. Multi-station switches are wired in parallel; switch wire 1.5 mm² (16 AWG, as printed).
AC wiring for V8/9/10/12 is published separately by Lewmar.

The cable tables call the breakers 66000894 (200 A) and 66000895 (250 A); the wiring diagram gives 68000894 and 68000895 (as printed).

Hydraulic System

Connect to a hydraulic powerpack with a directional control valve.
V8: high-torque motor on a 90° or in-line gearbox; not self-sustaining, so fit a dual pilot operated check valve (POCV); a chain stopper holds the load permanently. Ports A & B 3/4" BSP; Hi-Power drain 1/4" BSP, drain line minimum 6 mm bore, 10 bar.
V9/10/12: in-line gearbox with brake, self-sustaining. Section 5.7 gives A & B ports 1/2" BSP and a 1/4" BSP drain (Fig 5.7-2 labels some V9/V10 drives 3/4" BSP); drain line minimum 10 mm (3/8") bore, 10 bar.
Hose to A and B ports: reinforced braid to SAE100R2A or DIN 20 021 Part 2. Up to 30 l/min: 1/2" (13 mm) bore; up to 40 l/min: 5/8" (16 mm); up to 57 l/min: 3/4" (19 mm).
Minimum hose bend radius 6" (150 mm). Speed follows oil flow; slow running or weak pull points to flow, pressure, swapped ports or kinked pipes.

Operation

Release dog drive: tighten the band brake with a winch handle, then turn the top nut anti-clockwise to raise the capstan until the dogs are clear.
Engage: lower the capstan onto the gypsy until resistance is felt, back off a quarter turn, press UP/DOWN and the dogs spring into engagement; release the band brake before powered use.
Free-fall: dog drive released, then ease the band brake to run and stop the chain.
Warping: dogs released, brake on, chain secured to a strong point; at least 3 loose turns on the capstan. Never wrap chain on the capstan.
At anchor, hold the chain on a chain stopper; never break out a fouled anchor or pull the boat up with the windlass.

Servicing

Regularly: fresh-water wash; strip, clean and lightly grease above-deck parts; check brake band pins move freely and drain holes are clear; repaint any corroded below-deck parts with enamel and grease exposed metal and hose connections.
Annually: clean and grease electrical connections, check cables, inspect all below-deck paint.
Changing the gypsy: remove shoulder screw and top cap, drum and chain cover, spiral spring clip and tab washer; refit with the gypsy engaged in the band brake, wind the drum down until the dogs clear by 2 mm, threadlock the M6 screw, then wind fully down. Make sure the spiral clip is in its groove.
