I’m at a bit of a road block due to being a newbie. I would like some advice on wiring up my boat. It has a blower motor from a car heater as a motor, a raboesche bow thruster and a 1060 esc and I’d like to power it off a 6v battery. It has a dumbo rc receiver and a Futuba servo. My question is can I run it all of a 6v lead acid or would I need a separate battery and esc  for the bow thruster?

Darren:
How many channels does your receiver (RX) provide? 

The 1060 ESC, if I'm not mistaken, is designed to run on, either 2S lipo (7.2V) or 6 NiMH cells (7.2V), at a minimum.
The car blower motor, I'm assuming is designed to run on 12V, may still work at 6V or greater (with less power).
The bow thruster will likely run fine on 6-7.2V, but you still need some type of control (rc switch or small ESC) to choose the direction of the thruster (port-off-starboard)  Thus the question regarding available channels on your TX/RX set up.
It would appear that 6V will not meet the requirements of your 1060 ESC.  I have not attempted to run a 1060 ESC at 6V, so perhaps someone else can correct me if wrong.
You need to address the issue of the switch/esc for control of the bow thruster.

Hi, sorry I made a mistake the sla is 12v not 6v

[Darren007]

The rc gear is 6 channels

[DocMartin]

Your gear sounds good with 6 channels.  12V SLA should be able to power everything.  All you need is the transmitter controlled switch or secondary ESC to provide directional control of the bow thruster.  Opinions differ regarding control of the bow thruster, but my preference is an RC switch (on(forward)-off-on(reverse)).  In my mind, speed control of the bow thruster motor provides little benefit.

Hi, when you say a rc switch what do you mean? I agree proportional control isn’t really necessary but I’m not sure what you mean when you say a rc switch

Several MBM members have used the Action Electronics P44 Universal Twin Switcher:

https://www.componentshop.co.uk/p44-universal-twin-switcher.html

However, it is expensive and currently out of stock (as such for the past two months).  I put this here because the data sheet found at the above link gives a good display of how to wire a motor to a twin switch or relay.

Cheaper versions are available at AliExpress or Amazon (shown is the US link not UK):

These are inexpensive, but you need to have one with two "channels" or relays.  These are transmitter controlled relays, where only one relay will work at a time.  This allows you to wire one relay for forward bow thruster motor motion and the other relay for reverse bow thruster motor motion.  With a flip of a switch on your transmitter, you can have port or starboard control of the bow thruster.

Will the bow thruster be ok to run on the 12v sla? I have a hobby wing esc with a bec so it should be ok??

Probably not. Most commercial bow thrusters going right back are fitted with some form of 380/400 size motor. These are usually designed for 6v or 7.2v input, they will scream their bits off at 12v!
Best to fit a lowish capacity 7.2v battery just to run the bow thruster. I had this sort of twin voltage set up in an Our Lass 2 fishing boat. 12v gel battery running via a 12v speed control, and a 7.2v 3000mAh NiMh running the bow thruster and the radio equipment in the model, via a lower voltage rated speed control.
