it should turn right or you can swap the wires around to correct the direction
cheers

HI Les thank you for ur help .any one know when the brushless motor shaft is turning dues it turn left ? or right?when the boat going forward .I need to know be cuz im getting a new brass propeller

many thanks cliff 😀

Hi
I use an Emax GT4020 brushless outrunner in my 49 inch perkasa. its a single motor driving a graupner 55 mm plastic prop.
The link below shows the boat running on a 4 cell lipo but I prefer using a 5 cell which makes it a bit faster than you see in the video.

I think the motor comes in two Kv ratings. Mine is the 620kv.

Using one 5000 mah 5 cell Lipo I get 40 minutes of mixed speed running including quite a lot of ripping around.

HI thank you for ur help on the brushless motor 😊

many thanks cliff

Hi,
I use the same motor on both my 46" Fireboat and on my slightly bigger Perkasa. it is the Turnigy AquaStar 4084-620KV, run with two 5000mAh 4 cell (14.8V) LiPo batteries in parallel, and this gives both boats a brilliant and potentially slightly overscale speed and a long run time.
Go to http://hobbyking.com/hobbyking/store/__31678__Turnigy_AquaStar_4084_620KV_Water_Cooled_Brushless_Motor.html to see it.
Both boats are single motor, single shaft, 3 blade propeller, the Fireboat has 50mm prop and the Perkasa 55mm. This motor will produce 3kW in short bursts but is relatively lightly loaded in these boats so it has power capacity to spare. The kV value is just the rpm per volt applied to the motor so a 620KV motor runs proportionally slower than say a 1600kv motor which is probably too fast for this sort of boat, and it means you can run a bigger prop. For the speed control I use see my boats on this site.

I run on two EDF 1400kv motors in my perkasa they are just as good as more expensive Turnigy Aqua Star motors
