Testing Engine (Out of Ski)
I just about have everything I need to fire up my engine, except for a starter. I am wondering if its possible to hook up the electronics and fire up the engine outside of the ski. Would the engine have to be mounted somewhere first? Or is this idea even fesible?
1. How would I relay gas in the engine?
2. What about cooling?
3. Anything I should do for the first time when starting this engine. It has a new head, thats it?

Did that one time with a Chevy 454, but I had it mounted to an engine stand and connected to a overhead hoist. I would think you would need to have it bolted to something to keep it from moving around. For gas I simply feed it from a big squirt bottle, as long as you dont run it to long you should not need any cooling. But I am just going by my experience with a car motor.

If you did do it I would reccomend installing the exhaust.If it was me I would wait till it was in the ski.If your ski is not there and the you want to make sure the head isnt leaking etc,put the exhaust on it hook up electonics gas and oil if you have a oil tank.Put the motor on a skid and strap it down.You can even hook up water if you want but it seems like a lot of work for nothing.If you dont run water dont run it for any length of time.If the skis there why not drop it in.
Remember theres no load on the ski and no cooling

Yeah I don't have the ski here. I'm in school as a student so theres no room in the garage which is a bummer. I have it on my workbench downstairs. I plan on building a stand. How would I feed the the carb fuel, by dumping some in there?

Why are you doing it just to make sure the head doesnt leak ?
You can put the gas in any container,use common sense
I would just wait till you get to the ski its a lot of work for nothing.
Did you torque in 2 stages and follow the right bolt patern.
If you did and didnt stip any threads the head should be good anyway.

Furthermore when you drop in the engine do you do it with the exhaust on? Or do you do that second?

I do it with exhaust off carbs on starter in front cover either off or on.Some split the exhaust at the elbow I take it all off.

I can lift it in and out easy enough I find the hardest part is the exhaust manifold bolts.
Give yourself a few hours and take your time hook up the water to the exhaust man and wire the starter before you put the exhaust on whille its easy to get too.
