ok this is a tricky one.. well for me anyway searched on Google so here goes im a newbie to all this so go easy on me if its a silly question
i have my hull water tight (no prop shafts ) and im now wondering if i will have enough power to move the weight of the boat/batteries and so on.
i want to use 3 motors all with 50mm propellers
power will be 12v
the motors i want to use are
Johnson 600 size 3 - pole
12 volts
No Load speed is approx 20,000 rpm.
Dimensions: L65mm, D36mm, Shaft diameter 3.2mm Off load Current: 1.57A
im not looking for speeds of 1000mph
just a nice cruising speed will do me
i will weigh the hull later along with the batteries and post results here later today.
the hull is 6ft long
i have 3 led acid batteries and am i right in thinking if i use all 3 but wire them up Parallel this will give me longer running time ?
hope someone can help
