Looks very nice mate,get some floatation in there mate right way up front and down sides,i use pool noodles the long tubular floats £1 from poundshop
,dont forget to grease your flex shaft,mix 16/1 ratio synthetic oil for the motor and have fun
.Are your water lines silicone? they look plastic or pvc if so they will melt in 5 mins also one thing i see is your antenna wire reroute it as its very close to the pipe which could be a problem if it touches when been bounced arround at 40 mph.Dont forget to run the motor in if its new,i run a full tank through at mid throttle with short bursts now and again,after 5 mins running bring her in let her cool down fully then restart and run for a few more mins then do same again.Once thats done just run her but dont go full throttle till second or even 3rd tank,this is my method for running in others may differ but i like my motors to last
