Siimon, what have you done
Entered the world of BIG toys
Don't forget, it's supposed to be fun.
So, to start:
I will suggest things in the order I usually build, but as ever you're your own boss
I assume that Paul hasn't sent any set up instructions with the hull. The first thing to do is phone him up and ask for them. He should provide them with it.
As there WON'T be a build sheet with it (use nitro sniffers do things the hard way)
you'll have to rely on us motley band for advice :'(
I always lay everything in the bottom of the hull in the approx positions I think it should be and look for any obvious problems.
Before you start you should have - the radio box, the tank and the engine (on it's mounts). This will enable you to see how they will all fit. The radio box (I make my own because I like a certain style) goes back next to the transom. This will tell you how far forward the tank (or bag) can go. Now lay the engine in where you think it should go, and any other bits as near as you can get to the positions they will live in (plastic bag with drive back end, trim tabs and rudder in, clipped to the transom) to give you an idea of weight distribution. It should, with the top on and all the bits in about the right place, balance about 1/3 of the length from the transom.
Adjust the engine position until you get a decent balance, then mark the position of things inside the hull with a pencil.
The hole for the shaft does go at the bottom of the V, dead centre. Drill the hole a lot smaller than the tube size and open it up with a round file. This allows you to get the hole right into the V. Keep your file level with the inside of the hull. The shaft is going to exit parallel with the bottom of the hull and as low as possible.
The engine, shaft and skeg are all going to be put in together so that they line up
Has the Makara got stringers up the inside of the hull. If it has, you can estimate where your engine will be mounted (low as possible but with enough clearance to allow for vibration movement). The angle of the engine should be so that the output shaft aims directly at a point halfway between the engine and the shaft hole in the transom (remember the shaft tube is going to be bent soon). Now you need a piece of 1/4" diam straight bar about 2" long (I assume you're using a 1/4" flexishaft). This is used in your engine coupler to align the shaft tube. Also stock up on plasticine which is used to support things until they're correctly aligned.
Part 2 tomorrow.

Ps Don't suppose you live anywhere near the Midlands, we could do a photo build (it's quicker than writing it down)
