I see it looks good. This my setup as of yesterday

Looks good. 

...please remove the fire hazard paper filter and get a K&N.

Thank you. That carb and filter are both not staying on the engine. They are just on it to keep stuff from falling down the intake!

There's a great video that shows a demonstration of the importance of proper driveline phasing.  www.macsmotorcitygarage/driveline phasing.  Spicer (cardan joint mfg. co.)  recommends up to 2 degrees of joint angle. There's also a very good discussion on the perf. boats site of this topic in the dyno section. It rather important to get it right. I hope this helps.

How do I check the angle on the drive shaft?

Do you mean as it sits,  or before you install it?

I am a big cheater. I made a rigid driveshsaft and basically have a pipe set up to go through a mock block. The rigid driveline is set up dead straight.

Once every thing is measured and marked,  I raise the engine 1/4" front and back.

If you lay the driveline flat on a table,  you can scribe a line across the joint caps. You can then use an angle finder to figure the offset using the center of the center yoke to figure each side. They MUST equal each other.

Ok thank you guys. It's already in the boat I will have to go buy the angle tool and check it. I had scribe marks on the shaft and we lined it up.  Hopefully I got it right or the engine will be coming back out.

I have it installed already. I can't lower the front of the engine anymore. There isn't any where to drill through. My friend can make me a new mount so I can lower the front of the engine more.

Looks like you need to lower the entire engine evenly

Unfortunately I can't lower the front anymore until I make a new front engine mount. I will make one this week. I had a friend help me install it. This time I'm going to do the work myself. I have a old school angle finder I used at the machine shop I used to work for. I will be using that when I redo it next week.

I'm seeing the front needing to go up,  not down.

Where are you located?

So looking at this picture,  you need to lower the rear and raise the front. The angle on the joint caps should be identical measured on the top, there should be a slight elevation change (up or down) but the angles identical. Right now it looks "nose down".

Ok damn I'm happy you said that before I went and made a new front mount.

So we got the degrees down to a 4 degree angle. Shaft looks a lot better.

Ok sorry it's 3 degrees
