I am pretty excited to announce the “Venom Vent” is now in production! Patent pending. This drop in vent will fit all Mercury V8’s. We have made a mold of Steve Bishop's handcrafted design in effort to create a clean affordable solution to bringing more air into the heavy breathing V8, and cut down on pulling exhaust through the rear air plenum. Every one is hand laid glass, finished, and painted. It will come with a template to cut the holes and access to a "HOW TO INSTALL" Youtube video. Installs with this two-sided tape or can be siliconed or epoxied in. We will doing performance gain tests soon. $495 a set plus shipping. Custom colors available. Installation video will be available shortly. To order, email Liberatorboats@yahoo.com

Nice. I am surprised Mercury didn't figure this out during R&D. Good on you 👍🏼.

Mercury's using these engines to push fat tubs around where they're allowed to be lazy. Randy is ragging those fuckers out and making them do some heavy breathing! I think these are going to be a hit.

Would be cool to flip the scoops as well. Both options for the consumer.
Let it breath either way. Can't win if you don't play.
Looks good.

Looks way better than the vents DCB was using on one of there twin 450 M33s. Are you getting any extra MPH? I know guys were running with the cowls off and gaining quite a few MPH.

This reminds me of my HF 3500W generator....I couldn't find any real good place for the air to come in so I opened up the oil check access door with it running and if I let go of it about 1/2 way open...it'll suck slam it back shut.

We plan on doing some testing with the vented cowl and stock cowl soon! Acceleration and top end. Only problem with the 450 on a 22 Liberator is that every prop hits the limiter. I'll load the boat with passengers to see the difference in top end. Stopwatch for acceleration.

IMHO, regardless of performance gains, these are a homerun!! They really break up the overly bland cowl and add some attitude to them I think. Kimda like the alien cowlings do on a 300x and xs.

Awesome job Randy!

Will look awesome in carbon, and a silver carbon would as well be an awesome touch, not that I’m in the wacker club tho.
