I couldn’t tell by pics but did you reduce the number of holes with the new 120 stats or you going to wait and see how they react. Tks for the info.

That’s a good point. How many times I’ve looked at that intake and saw the divider however never gave it a thought. They went to Jim’s to raise the floors and some porting. I’ll mention to him to remove.

Whats the purpose?

I'm planning on putting the boat up for sale when we return from Arizona for Desert Storm, that's at the end of April, so we need to do it early in the season! or it may not sell at all then we have all summer. Hard to sell a 38FT cat with a full cabin that runs 120 MPH!

It’s always nice to see the pride you take in your work 👍👍👍. Also Tks for the post. I couldn’t tell by pics however from what I could see looks like you dumping individually as well?

Thank you .
Dumping them individually above the drives , yes.. I thought about using them to cool the drives but they never really get hot.
For a bravo it might be cool idea

I did not put any holes in them. They come with 1 hole in them for air pockets. I will probably not drill any holes in them right away. I'll see where my pressure is an go from there. I also just put those in my Merc 420's w/ 500 EFI cam builds. Those engines ran hotter water and oil than I like with 420 stock hardware. Nothing like spending $160 on thermostats. Why do I do this again... lol

Gives it Direction.
Forces water up there vs the two columns of water crashing into each other, then going up. Water flows similarly to air, but with a little mire weight.

I'll cut them out tomorrow while I'm at the shop. lol

Can you quantify mire for me? I must have missed that unit in my engineering classes...

I run in water temps that range from 34 to 76 degrees. I have a 524CI BBC that's a GM Mark IV block with AFR heads and a Brodix HV2000 intake, and Lightning headers. I am running the Hardin stainless pump that I have ported for better flow with a crossover and racing 160 thermostat. It came with 3 3/16" holes and I still have the divider under the thermostat. I added a -10 line from back to front to even out the cooling. According to my lab grade IR temp gun the front and rear of my cylinder heads are with 2 degrees of each other. I have slightly modified the headers to allow for more flow as well. When running wide open across the lake I run about 165 on the gauge. idling for any length and I'm 140-150 if the water is warm. When Lake Huron is cold, I'm lucky to hit 130 pushing it. My oil cooler is a bit too small, but with Amsoil as long as I'm under 300 degrees I'm fine. I couldn't ask for a more consistent and even cooling system.

Yes. My finger pads are worn slanted. I pressed ‘o’ on my phone keypad but got ‘i’. So, tried to type ‘more.’
