Default my first boat

i been into rc cars and trucks for hmmmmm a long time. never had a boat so i made a trade on rcu and got a brand new 48" prather or pranther deep v, i don't know. has a 30cc homelite weed wacker motor, guess its gonna be direct drive because i have no clue where to look for parts so i'm counting on all you guys and gals to help me out on this build. i think its gonna be cool. i have everything but mounts that i'm gonna have to build for the throttle and steering, i forget its a boat so i guess its a rutter. i need some sort of gas tank also. lol i am pretty green on boats but smart enough to figure it out. (i think) seems like a clutch would be best but i have the adapter on the end of the crank now to make it direct drive. the weed wacker spool cable fits into it and i am gonna solder or braze it. the other end goes into the prop shaft with a set screw. i just got a couple coats of primer on it today so now its time to start mocking it up. gonna try and keep you posted with pix as i go. thanx and any suggestions would be grateful.

Be sure to leave the cable between 3/16 and 5/16 inch long to allow for cable shrinkage under load

In your pics I don't see any 5/16"brass stuffing tube,but you have the engine mounted and the stinger drive in place.Maybe I do it wrong but I figure out where the CG will be on my hull and put all the parts in the boat that's going inside the hull,in the places that they'll be and also tape the rudder and drive on the back.I put the radio box where I want it with everything in it (servos,switch,receiver,battery) and move the the engine to get the boat to balance at a point that i marked on the outside of the boat.Might have to move the engine and radio box slightly to get the balance betwen 28 and 30 % of the hulls length.I then cut and install the stuffing tube and bend slightly to align with the engine output end.
Don't brase the flexshaft to the out put on the engine.That's where your cable will move and contract inside the square drive.You'll have to be able to pull your cable out to grease it or maybe replace it. How are you going to keep you prop,shaft and flexshaft from flying out the back of the stinger?

By the hull design of your boat it is either a Prather Commander II without a hatch or the Offshore Style Deep Vee. The length of both hulls is 46" x 14" wide.I had the offshore version and it ran slightly over 50 mph with a mild mod Zen 260 in it.A stock Homelite will probably get you between 25 and 30 mph and will make a good boat to learn with. You could cut out the area around the cannister exhaust and plug that hole.It will blow oil all over your boat.Most put two 1/2" stacks on the cannister.You can upgrade the engine as you go along or buy an engine made for boat use.

The stinger is the thing in your pic that has the prop on it. The 5/16" stuffing tube is what your weedeater flexshaft rides in, otherwise it woud just flop around. It runs to almost against your output on the engine to the rear of the transom or a little beyond for a surface drive setup or may go out the bottom of your hull for a sub surface setup.Where it exits the hull you shound have a short piece of 11/32" brass tube for the 5/16" to go through and make it easier to replace the 5/16" if necessary.Below the red boat has a sub surface setup, where the tube goes almost to the ferrule(tapered brass piece that conects the flexshaft to the prop or stub shaft).This is a strut setup instead of a stinger. On the black boat it is a surface setup with the tube exiting the transom to almost the ferrule.
The piece of wood in the pic is what I used to make a wedge to bring the strut up more on the angled transom.
