FAQ’s: Momentum M10 Motor

Please note

The MB6 battery can only be charged from the original Momentum chargers due to the safety requirements of the integrated Canbus system.

This means that the charger and the battery perform a security handshake before any charging can begin to ensure that two compatible items are working togeher.

The standard charger is an 85v 18 amp charger and so it therefore charges at around 1,500 to 1,600 watts.

As the MB6 battery has 6.4kWh of capacity it means that the battery will generally charge from dead flat in well under 5 hours, but of course the battery is very rarely going to be completely empty.

The great thing about this charger is that it only draw around 7 amps from a normal 3 pin plug socket so it can be used at pretty well any standard harbour power bollard without fear of tripping it.

In summer 2026 a new faster charger will become available which will be an 85v 30 amp charger so capable of charging at up to 2,550 watts. The input power is limited to 11 amps so there is no problem with it potentially tripping a standard 3 pin 13 amp plug and this higher charging brings the time to charge from zero to hero to just over 2 1/2 hours.

This is still a very low charge speed for these very high quality batteries so you will not ned to worry about over charging them or them overheating as the powerful Battery Management System takes care of everything maintaining an active connection and dialogue between the charger and the battery.

The tiller pulling to port if perfectly normal when using the Momentum M10 and it is due to the prop rotation and the prop being at the end of the motor bulb, giving rise to a mechanical force that casues the boat to turn to starboard.

This is because the rotational force of the prop is quite a long way behind the steering pivot point and when the tiller is locked, the twist (P-Factor) viewed from astern creates a side thrust that pushes the stern to port, causing the boat to turn to starboard. When instead the tiller is free to move, it has the same effect by pushing the motor to starboard, which pushes the stern to port and hence turns the boat to starboard.

It is especially noticeable when under higher power and when the steering damper is not very tight and it is nothing to worry about regardless.

Some users like to have a very free moving tiller that easily moves side to side for very fast and agile manoeuvering but users who are manily based in choppier waters while still wanting to go fast often like to tighten the steering up quite significantly to reduce the tiller slpapping around especially when taking off over waves as we do very often in the Solent!

The M10 can counter this effect very simply though if required by simply taking an Allen key and using it to evenly tighten up the 4 allen key bolts in the black steering damper found on the starboard side of the M10 motor:

Users can do exactly the same if they are using the M10 with the remote steering with some liking to loosen the dampers to make steering very light as the natural resistance of the cabling naturally reduces the turning to starbaord.

PLEASE NOTE

If you are using the throttle tensioner on a tight setting but the stering tensioner on a very loose setting, letting go of the tiller handle can cause a dramatic turn to starboard!
