Yellow Boat 4 twin NQD jets driven by P2632 Brushless Outrunner 3800kv Brushless



Yellow Boat 4 





Twin NQD jets modified with brass stern tubes.

I have alternate nozzels which are a little larger than standard also.







Brass impellers made from cutdown brass props

Two P2632 Brushless Outrunner 3800kv Brushless


 
Stern Tubes brass shafts wrapped in PTFE tape until they fit the tubes. Will be setting up air cooling system with small EDF fan.

Will probably run two 2200mAh Lipos and 50 Amp aero ESCs with big heatsinks


For the cooling I may have the Arduino open and close a vent with a servo if the heatsinks get hot, as well as controlling the fan speed. 






Based on yellow boat plans different deck 390 Grams as shown 
Also Ply fiberglass epoxy catamaran build log

Glass and epoxy inside balsa ply, will epoxy the outside too. Its very strong with builders fiberglass tape and epoxy 



The motors will be mounted further forward on a cooled plate 














Spray rails are bamboo barbecue skewers and wood filler
