OK...my 79 255 Formula with twin Bravo I's is currently set up for right hand rotation port and starboard. My rigger that set this up said that he had to do it that way because of limitations in my 1979 Morse Controller, I was told if I get a newer Kiekhaefer controller that I can run port side (the side that needs to turn ccw) reverse by switching/changing something. oK...so now I have a Kiekhaefer Zero Effort controller to install. What needs to be changed? Is it at the controller or at the drive.

I really want to do this but can't tie him down as to a time to do it so I thought I would do it myself if it's simple enough.

Thanks

The change is at the shifter.
One shift cable comes in from the front and one from the rear. One lever pulls the cable and one pushes the cable to get you counter rotating drives
One cable may need to be lengthened to make the U turn

OK...thanks for that. I think we installed new shift cables with the drive change so this should be simple.

you also need a left hand prop...some people like them turning in instead of out too. apparently improves stern lift.

Spin in to win John!! Lol

This is probably one of the easier things to do. Mine took about 15 minutes start to finish!! Screw driver and pliers to bend cotter pin.. probably 5 min of that was getting the grease off my hand and seat

Here we go guys:

This week I finally got the Kiekhaefer Zero effort Controller installed. I learned another "Old Vs. New" lesson with this upgrade.

In review...after swapping the old MR-I Drives to Bravo I learned that the original 1979 MerControl would not allow for setting up the Bravo I's in reverse rotation.The reason is that Bravo Drives require a modern control such as the Kiekhaefer that will allow the shifter to push or pull the cable to make the Bravo I rotate either right or left hand rotation. I purchased a used Zero effort here on the OSO Swap Shop at a good price. It was in great operating condition but had cosmetic "issues". I sanded it and repainted it and it looks good as new. As I prepared to install the Kiekhaefer I discovered that the control end of my old original cables were different and were the old Mercury 600 series style that doesn't work except with old Mercury controllers. So...after consulting with Jason at Brand X and my friend and expert "Li'l Red"...we determined that I needed all new cables...shift and throttle. I measured the old ones and off to Jerry's Marine in Ft. Lauderdale I went to pick up the latest Tele Flex "TFXtreme" cable in the correct lengths with the correct ends that thread on.

So out came the old head and cables and in went the replacement Kiekhaefer and cables. We adjusted the linkages, wired up the neutral Safety switches, swapped the 23" Mirage RH on the port side drive to a 23" Mirage LH. Now I have both drives rotating outwards....which was one of the advantages that one gets with Bravo Drives.

Hey guys...with the new cables and controller in place I now know for sure what everyone was talking about when they said "Zero Effort"....they weren't kidding...it is Zero Effort!! Now I understand how those Throttle-men in the Off Shore Races are pumping their arm back and forth "effortlessly".

This is just another one of those things you encounter and find a work around for when you are updating a 35 year old power boat. When my 79 Formula was built. Bravo Drives and Zero Effort Controllers weren't even on the drawing board yet and were 10 years from production.

Special thanks to Jason Ventura at Brand X in Pompano Beach and James Dow aka "Lil Red" for their assistance and guidance in helping me thru this phase of the project.

You can teach an "Old 'Bird" new tricks. LOL

Pics to follow.

you put a pic in somebody's thread the other day. gorgeous boat. pretty nice driveway too...

Thanks...oh and I put the LH prop back on the port drive also...LOL
