M6 / M8 Prop Aerator Kit

MULTIPLE PART NUMBER OPTIONS. CLICK PART OPTIONS FOR MORE INFO ->

M6 / M8 Prop Aerator Kit

This custom prop aerator kit is designed to allow air to the propeller which helps large boats with radical engines come on plane easier. In pleasure applications, the aerators take the load off of the props when maneuvering around docks, and help to prevent engine stalling when engines are shifted into gear. In race conditions, aerators improve throttle response coming out of corners or after hitting down on a big wave by instantly relieving the load off of the propellers. Hose and clamps included.

Requires drilling a 3" diameter hole in the top of the lower drive. Lower stainless piece is cut to fit and must be custom fit to your propeller.

Bravo Anti-Cavitation Cap

221-2002

Bravo Anti-Cavitation Cap

A revolutionary solution to a long-standing issue facing many performance boaters with Bravo style drives. In our never-ending search for top speeds, we install shorty drives with high X dimensions trying to chase a big number. While these upgrades frequently increase top speeds, they commonly lead to frustrating challenges just trying to get the boat on plane. Top speed numbers are great, but struggling to get on plane without your family and friends having to huddle in the front cabin is just not fun.

Identifying the Issue

MDC’s Bravo Anti-Cavitation cap is a simple solution to a complicated problem. After researching the issue, with the help of one of our dedicated customers, we discovered that the propeller is cavitating because it is also drawing in air through its hub, and not just from the surface, as most would believe. When you hit the throttles to get on plane, a low-pressure area is generated by the propeller as it tries to push the boat forward. Being that water is about 800x denser than air it is easier to just pull air through the hub and from the surface than move the water. The direct result is cavitation. Having a high X dimension / shorty lower just exacerbates the issue by making it even easier for the propeller to pull air from the surface and increasing the air that was already being pulled in through the propeller hub.

The Solution

MDC’s Bravo Anti-Cavitation Cap blocks the source of the air that is being pulled through the propeller hub. Cleverly designed, and easily installed, the Cap fits over the thru-hull exhaust input for the drive. Obviously, this system will not work unless you have performance thru-transom exhaust, and no captain’s choice or thru prop. Installation is easy and does not require removal of the drive. The system has been tested on numerous boats that had issues coming on plane, and every one of them not only saw significant improvement, they no longer require any special efforts to get on plane. So, instead of swapping out your shorty and losing speed just to be able to get on plane with your family and friends onboard, just install the MDC Bravo Anti-Cavitation Cap and go boating.

TrimSync - Trim Monitoring and Alignment System

MULTIPLE PART NUMBER OPTIONS. CLICK PART OPTIONS FOR MORE INFO ->

Operating a multi-engine offshore powerboat can be a little overwhelming at times.  That’s probably why offshore racing is the only motorsport that requires two drivers. Most offshore boats have an engine trim button built into the throttle lever handle.  We all know that the drives rarely stay perfectly even using just the BOTH button on the throttles.  Having them offset can impact handling, and can be dangerous at high speeds.  So that after a couple of moves we are all reaching to the dash to try and even them out.  Over and over again.

TrimSync is a patent pending device that monitors the trim for twin and triple engine boats, so when the operator presses the BOTH/ALL button, it will automatically adjust the drives to be in perfect alignment, every time.  You will never have to worry about how accurate your mechanical trim indicators are because TrimSync will always move the slowest drive to match the others.  There are no extra buttons or complicated operating instructions, just push the BOTH button and TrimSync does the rest.

If, for some reason, you want one drive to be at a different trim then push that drive’s trim button and it will move just as it always has. TrimSync will re-align the drive trim the next time you push the BOTH button. Just drive!

NOTE: Please specify when ordering if using Mercury Racing Engines.
