Idiot questions before firing up for first time!!

If you have a RH (reverse rotation) PCM, then no- you have the direction of rotation marked backwards on the RWP pulley. Confirm which way your engine spins and take another picture from the side and we can tell you whether the pump is installed properly or not (its common to install it upside down, which doesnt pump water into the engine very well). Do not worry about which way the impeller fins go- they'll correct themselves.

In regards to setting your timing, it sounds like you found the compression stroke properly... you dont mention turning the engine to TDC on that stroke (0-10 deg BTDC) before marking which direction the rotor faces- did you do this? You dont mention the fact that you will be installing plug wire #1 on the cap post that lines up with the mark you made, but Im sure thats your plan, and to follow the firing order around in a CCW direction as well. (Right?)

The instant you get the engine started, youre going to want to time it properly, so go ahead and get that timing light so youre ready for the initial firing.

5L is a bit overfilled (5L = 5.25 qts) but close enough, I suppose. Pre-filling the filter is preferred, but not required. No worries on the tranny fluid.

Thanks for the replies.
Regarding timing, I checked the balancer after marking the dizzy (when receiving pressure on cylinder one), in order to line it up to tdc I have to continue turning another 40deg on the dizzy - does that sound right??

You'll have to bear with me using phone whilst sat on boat!!

Compression starts building as soon as the piston starts moving away from bottom dead center (towards top dead center).

Either way, timing is referenced to TDC so don't worry about it. The trick is just to make sure you don't go off TDC on the exhaust stroke (180 out).

Was cranking engine backwards, hence reason for putting arrow on RWP the wrong way round it's reverse rotation   
Think I have it now, well it line's up with tdc on balancer anyway.
You mentioned possibility of being 180deg out putting timing on exhaust stroke, does this mean that I can only time from every other full cycle on the dizzy, it's just I'm getting enough pressure to pop my thumb off the plug hole on every cycle as opposed to one in every 2 cycles..

Excuse the stoopid questions, I have experience with working on cars but always electronic, fuel injection none of this distributor malarky!!

Dizzy and the cam spin at half the speed of the crank. If you're 180 out then 6 would be on the top of compresion stroke instead of 1, it's 180 on the dizzy from 1. Move the wires so that 1 is where the rotor is under the cap, you can twist the cap to do that or move the individual wires.

The balancer and your mark aren't adjustable so that mark comes by 2 times to complete one trip through the firing order. If you wanted to be lazy you could try it with the mark lined up 50/50 chance it's right, if idoesn't spin the mark around 1 time and it would work the next try.

Once it runs thins is like everything else, you'll. E able to do it quick and painless next time.

Tranny usually takes about 2 US quarts.

It runs!!!
Fired up on first crank, probably helped by sucking the fuel through to the lift pump by mouth like a true redneck!!
Took it up to WOT in neutral, but didn't get a chance to put the light on it or put it in gear due to the carb flooding fuel via the secondary valve. And lots of it!
When I first got the boat it was dipping fuel from the primary but I since installed a trick kit from Holley. Any ideas before I take it apart again? I recall the floats are not adjustable on this one, seem to remember its a 4160, definitely marine..

congrats on getting it started.

I wouldn't run it wot in neutral, get it in the water and in gear under a load before you run wot.

Looks like I need to strip it down again then
