BrendanR what is your 201 Liberator’s setup? To hit 85 mph you have to be running well over 500 hp, Probably 575+ hp.

Running about 625hp. I have a full mayfair duel ram external steering kit and a max machine worx built xr drive with a 1.50 gear which next year will have a -2 shorty speed master lower and a 1.35 gear. It currently has a 4 blade 28p bravo prop which is also getting changed. The setup is a 509, big cam, aluminum heads and a tiny heat maker on top. I just picked up an m1sc that's going on in about 8 weeks

BrendanR so you are joining the Procharger crowd. 625 hp is a lot in a 201 Liberator.

Yes, joining the procharger crowd because I got a good deal on it. I have plans to build a twin turbo 540 but it will end up in a larger hull. Family always had liberators and after researching and finding the 108 mph 261 I said, I'm going to beat that. This thread intrigued me because I wanted to see if anyone else beat that record yet in a fourwinns. So far, I'm at 85 mph with no tabs and a 4 blade prop. When the procharger goes on, I will be pushing the 850-900hp mark and lenco 18x12 ss electric tabs are going on this 201. As soon as the site allows me to post photos, I will do so.

I'm on plane by 25 mph. Last year I beat out a friend's 17' jet boat with a mild built 454. He swapped to his 496 and it was fast however I was realing it in but I believe because he was topped out around 70.

this is her.

This is the video at 82 mph at 5800rpm

Looks like you have the same exhaust that is in my boat. IMCO Powerflow exhaust manifolds with stainless steel risers going to stainless steel piping going to the stock exhaust ports.

I would like to see a video from shore or from another boat of your supercharged 509 Liberator running 82 mph or faster.

it will never let you post videos.
Videos need to be posted elsewhere like youtube, then linked here.
