One more thing joe since your checking this thread. I took the carbs apart to clean them and the jetting is as follows.
Both carbs have 84 primary's and 86 secondaries.
The front carb has a 5.0 power jet on the primary side and a 6.5 on the secondary side.
The rear carb has I think a 7.5 power jet on the primary and a 6.5 on the secondary.
35 squirters on the primary sides and 37's on the secondary sides.
That 7.5 power valve seems out of place or is it supposed to be like that?
How does this sound for a starting point?

As for your hole, you could make a box out of aluminum and then thru bolt it and spread the weight?? Actually... you could make a plate for the top and just add support brackets where needed. just a thought.
OH>> and that sounds Bad A$$!!

I put superchargers and turbos on eveything. Lol. It's a sickness
Got the boat out today and it was awesome. Still have the 30p bravo 1 on until I sell it and go bigger, but it ran what it did before except at what seemed like half throttle. :-)
I ended up doing one inlet in the chiller and two dumps. One per side of the boat. It added a cool look with the water spraying out the sides of the boat too.
I was sitting at the dock letting the boat warm up and the last guard heard it surging real bad so they (about 6 of them) pulled up and asked to see the motor. They were real cool and liked checking the engine out.
Here's a vid I made while it was warming up.

Here is a pic of the water pickup I made. Don't mind the 4200 spewing out every where. I didn't clean it off before the pic was taken.

Boat sitting at the dock while I parked the truck. Looks good...In my opinion.
