Thanks for the replies guys,

He wants me to have the boat in the future and has basically given it to me but I would like to set it up for him to drive. Therefore I will be setting it all up, including the costs. A run time of approx 20 minutes would be good.

I don't know it's full speed in mph/kph, and I have seen some smaller hydroplanes go faster. The speed may be 2/3s of what is in this video - http://www.youtube.com/user/Titanis2000. This boat can also handle some choppy water which would be too rough for them.

I think that a single motor would be fine if they can do the task, as I won't have to fit new shafts, rudders and water pickups and can use the existing. I previously set up the running gear for the boat as he always had fun with alignment and with the power of this motor the alignment had to be spot on.

I will check out your recommended set-ups with regards to price etc as we are in Australia.

I only suggested the twin motors as the current setup has a lot of torque and has trim tabs for stability, and twin would take care of that issue.

I run electric boats, but they are scale and the latest runs on 2 x Graupner 700bb motors with 2 banks of 8 x 9ah D NiMh cells that give me a run in excess of 45 minutes. There is a photo in my profile. This is totally different scene to the FE's.
