Tried it on 12v , but still no joy although i did find out why .
It turns out that the mfa 540 motor was previously used in a bottle boat and had the living daylights thrashed out of it (too big a prop V too many volts
).
So i will get another motor today Wed, maybe a buggy motor as they go like stink and are cheaper than standard marine type , and i can get it today from the shop.
But for future thought i am sure there are some good economical motore out there that could be recomended
.
