Boat ran great. Has a slight hesitation around  around 4600 4700 rpm. Im hoping its a rev limiter that im not aware of or the secondaries but i feel confident that it will perform well on the river. Im still going to get an MSD unit for piece of mind although i didn't notice anything with the Ebay HEI. Thank you to everyone thats given me advice.  Definitely some fine tuning but it idled well and responded well so im happy. Clocked at 48 mph at 4700 rpm but i let off and cruised easily at 4500 rpm around 45mph.

Awesome! keep at it, it will get sorted out.  Be careful at Perris, the speed limit is 35mph on the lake, dont know how seriously they patrol it though

Is the carburetor vacuum secondary or mechanical?

Sounds like the hesitation is caused by the secondaries trying to open. I had a similar issue on my prop cruiser boat, it would stumble badly and not accelerate past a certain rpm if you were at full throttle. You could back off a little and it would eventually come up on plane. I added a little bit stiffer secondary spring so that they opened later and the problem went away completely.

I also messed around with the power valve. There are a few old posts with some good responses and suggestions for the vacuum Holley carbs on a jet boat. I was satisfied with the results I got from just a few changes after I rebuilt the carb.

Time has not been on my side. I will be getting it out sometime this week after work now that i got all of these other things done. Lots of stuff going on but i killed most of it this weekend. Since i was welding I managed to make 2 pretty sweet removable flag poles. One for each corner of the rear. Unfortunately i didnt get to use them
