Electric boats have all sorts of engine sizes and styles.
Most of the advertised RC Brushless boats have small engines because of the cost of them, I have seen Brushless Motors for boats that cost more than the whole boat and hardware.
If you ask people into electric boats, there is no engine too big that can be used.
Another thing is with the more expensive/larger the motor the better the ESC needs to be and they are not cheap tool.
This is getting old so I thought I'd ask for an update and also instead of making my own thread would post here.
I'm thinking about getting a boat. All I need is the actual shell (if that's the right term) to put my own, radio, ESC and motor into. Nothing pro, just something that I can run around an avg duck pond and enjoy. What type of price am I looking at? Anything I should be aware of?
i scored an aquacraft nitro hammer hammer hull for free going to get a motor and a few other bits to get it going soon.Ive heard that they have a great turning circle like you just said suzukiboy:thumb:.Hope you get a hull soon ratsack
I am not overly knowledgeable on elec motors, but I would take a stab at the reason and say it is for economic reasons. They would do it the same way they set up 1:1 boats. When they set up an on water package they put in the minimum size motor that they can get away with for the boat to still get on a plane and cruise, but when you want to pull a skier the boat is under powered. The same would probably go for RTR RC boats they put a motor in that will get it going, smaller motor means cheaper boat and cheaper boat means more sales. If you want some excitement you have to upgrade to a bigger elec motor. This only my opinion so take out of it what you will.

The reason for the low KV is usually dependant on the voltage of the battery you want to run. The problem with running a high KV is that the prop can't bite the water enough and is actually self defeating. Anything above 60k rpm is way to high and won't actually work well.
Work out the KV value that best suits your needs and then with the battery size, you can work out the best motor to suit your purpose.
mmm that sounds logical then. I knew i couldnt spin the prop to hard but wasnt sure how hard was to hard lol.
think i will only be running a 7.4v lipo. MAYBE 2 in parallel but not higher voltage.
For starters the ESC i got only handles 2s lipo anyways. MAYBE one day upgrade to something different.
Atm is it purely for fun to see how the boat handles the submersible drive.
Havent touched the boat for a while work has been killing me. So will get some updates over the xmas period.
