Members PT Mike Posted April 23, 2013 Members Share Posted April 23, 2013 Is anyone working on a Zero Off conversion for pre 2002 boats without doing a total repower? Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted April 23, 2013 Baller_ Share Posted April 23, 2013 probably wont happen! But never say never! Stranger things have come to pass in this industry. Link to comment Share on other sites More sharing options...
Baller gregy Posted April 23, 2013 Baller Share Posted April 23, 2013 @jody_seal my friend has a 08 ps 197 that has both pp and zo. Does it use econtrol computer or the gm computer. My friend thinks its a 5. Link to comment Share on other sites More sharing options...
Baller skihard Posted April 23, 2013 Baller Share Posted April 23, 2013 I am under the impression Zero Off won't go on any boats older than 07? Am I wrong in this thought as their web page says only 07 to present. Link to comment Share on other sites More sharing options...
Baller thager Posted April 23, 2013 Baller Share Posted April 23, 2013 You can convert Ski Nautiques to ZO back to 2002 if they have the Excaliber 5.7 330hp chevy engine. Link to comment Share on other sites More sharing options...

madcityskier Posted April 23, 2013 Share Posted April 23, 2013 My 85 does just fine without. Providing you can find someone who knows how to drive, not just steer. That being said, I have been out with plenty of people who could benefit from welding the rudder in a straight line, as they would at least be predictable to other boaters, let alone the skier they're trying to tow.

Baller gregy Posted April 23, 2013 Baller Share Posted April 23, 2013 I've been researching this some. The new boats with ZO use an e-control computer. The older boats use delphi MEFI. My 99 Response has MEFI4 that is throttled by cable. From what I understand with inboardfix.com Nautique kit you install an e-control computer with a new wiring harness and hook the throttle cable to a potentiometer to convert to Drive By Wire (DBW). There was some legal agreement that PP would take the older boat and ZO the newer boats. The company that make ZO is e-controls. But, before the agreement - my ski partner with the 2008 MC ps197 has both PP and ZO. He thinks that it has a MEFI5 computer, so if that's the case ZO communicated with MEFI at some point. Are the parts still available? Other thought I had. So may 99 response has a GM vortec 5.7L 325Hp. The Excalibur 5.7 330hp. The intake for the Excalibur should bolt on to any Small block GM with Vortec heads. The similar hp ratings so the Cam and compression ratios should be the close to the same. So could I buy the intake and throttle body used on the Excalibur 5.7 and get inboardfix's kit and put ZO on my 99 Response? There's also DBW gm auto intake that could be purchased for cheap used that might work as well? Anyone else thought about this? If so let me know might be next winter's project.

Baller alex38 Posted April 23, 2013 Baller Share Posted April 23, 2013 Can a 2002 ski Nautique with 5.0 little PCM Pro sport be converted? Or does that need a different engine? Link to comment Share on other sites More sharing options...
Baller thager Posted April 24, 2013 Baller Share Posted April 24, 2013 A person could probably convert any e-control convertible type engine to ZO. That engine would have to have all of the required compatible sensors monitored by the ECU. If a sensor was missing I suppose you could modify and add it. The real question though is how much time and money do you want to throw at it to figure it out? It doesn't take much to make swapping engines cheaper. Seems to me one of our MN guys tried to convert a 99 or so Malibu Response but was not successful. Link to comment Share on other sites More sharing options...
Baller gregy Posted April 24, 2013 Baller Share Posted April 24, 2013 @Alex38 the only conversion kit I know of is for the 5.7 liter Excalibur 330hp. Link to comment Share on other sites More sharing options...
Baller thager Posted April 24, 2013 Baller Share Posted April 24, 2013 @gregy and @alex Seems to me there was a guy out of CA that figured out how to convert Mastercraft (Indmar) and had a kit I think. Saw it a while back on a SIA ad. Link to comment Share on other sites More sharing options...
Baller gregy Posted April 24, 2013 Baller Share Posted April 24, 2013 I can now install zero off in 2006 mastercraft boats with the mcx motor if you have our know of someone with a 2006 thats wents ZO installed my contact info is cell 909 -223-4427 or e-mail rip39off@aol.com Doug @Doug here on BOS. @thager @alex38 Think this is the guy. I haven't talked to him. Link to comment Share on other sites More sharing options...
Baller ForrestGump Posted April 24, 2013 Baller Share Posted April 24, 2013 @gregy The 08 MC with PP and ZO does not have a MEFI5. 08 MC's that got ZO were converted at the dealers to eControls ecu's. You could order the boat with it, but the parts were installed at the dealer. ZO has never talked to the MEFI. Link to comment Share on other sites More sharing options...
Baller gregy Posted April 24, 2013 Baller Share Posted April 24, 2013 Thanks @Shaneh. E-controls is the limiting factor then that's to bad tuning software for MEFI is pretty common. Not sure about E-controls. My friends MC is a 2008 TT 197 that was a promo boat. I've never seen him use the PP, pretty much just plugging a hole in the dash right now.

Baller eleeski Posted April 25, 2013 Baller Share Posted April 25, 2013 Hmmm, I'm thinking about a V6 ZO engine for the 79 American Skier. Another project?! Aircraft are often reengineing or retrofitting the powerplants. My Cessna is on its third engine- and the current engine is an upgrade from the original. I had several other options as well. Of course airplanes are a bit different - my 1978 210 is not considered old. Eric Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted April 25, 2013 Baller_ Share Posted April 25, 2013 I still think that early non cat MCX engines could be retrofitted to run with E-control and ZO. I have the formula, No one has stepped up with the R&D Funds to prove it out! Link to comment Share on other sites More sharing options...
