Basically..u start off with the motor mount.......then shaft and motor installation. Before drilling holes, its iportant to know the CG of the boat and mark approximately where to place the power unit. After that...u will have to fix the power unti with Epoxy.....
Then go for a water leak test first before sealing the top deck. Then install RC unit....then test again in water for any water leak.....
In the end....Paint the boat, and do the fitting and u are off to go~~~
