Title: Conversion 5ft mono ic boat /conversion to electric running
Post by: howard66spary on February 12, 2022, 06:06:52 pm

Good Evening To All
I have a ic powerd apache mono hull fitted out with a 25cc nitro engine and the relevant  hardware , 

The problem i have is the local  conservation group and fisherman take a dim view of nitro boats on the river , i also suspect that the local council would object
I do run electric without a problem so my question is could i convert it to electric i realize that some of the existing parts would have to be removed but would like to retain some if i could find a buyer who could run it as a nitro boat
No trim tabs or turning knives have been fitted
I would welcome any advice on a possible conversion at least this way it would not be wasted and not go as fast as the nitro


Thanks
Best Regards
H W Spary

Do you know the output power and RPM of the existing motor? I am assuming that you are looking at similar performance to your current set up.

Good morning all


Not very good with computers , but have found the spec for the engine tucked in bow of boat it is a s254 evolution version which looks to be mounted on a dedicated aluminum frame
I assume the water cooling system can be adapted for an electric motor , would leave the tuned pipe in and fuel tank servos are for rudder and what would have been throttle which are mounted in a waterproof box


Hope this helps
Thanks H W Spary

Hi Howard


I checked up on the motor and the specs are 5HP at about 17000 to 18000 rpm.


So that's your starting point !!!


So a brushless motor about 3500 to 4000 Watts !!!

If you’re looking to sell your RCMK I may have a buyer waiting :-))

Hi Andyn


Sorry for delay for a reply , have sent a e mail not sure if you recived  it but it read as follows
As far as i know the engine was fitted as new , it is in pristene condition the boat has never been run and is as it came to me


Have looked at the price again and the best i could do would be £190 including postage and packaging


Hope this helps
Best regards
Howard
