Baller dbutcher Posted July 4, 2016 Baller Share Posted July 4, 2016 Does anyone know if the new PCM engines will bolt right up in older Nautiques? If one wanted to repower an older Nautique to get Zero Off, could a 5.3 or 6.2 be used? Would there be any other issues such as too much power for the older hull?

Baller ozski Posted July 4, 2016 Baller Share Posted July 4, 2016 I think the real question would center around the business case more so than any other single factor. Link to comment Share on other sites More sharing options...
Baller eleeski Posted July 4, 2016 Baller Share Posted July 4, 2016 @ozski Business case? I just want ZO in my old American Skier. If it fits better and is lighter, I'd consider it. Unless I can buy a new boat for less. Really want a V6 ZO compatible engine. Any ideas? Eric Link to comment Share on other sites More sharing options...
Baller keithh2oskier Posted July 4, 2016 Baller Share Posted July 4, 2016 Any way you can get the 4.3 V6 from a Chevy pickup? Link to comment Share on other sites More sharing options...
Baller eleeski Posted July 4, 2016 Baller Share Posted July 4, 2016 I can get anything. Whether it is ZO compatible is the question. I do have a Chevy transmission adapter so that would be easy. Volvo has a marinized V6 with fuel injection. I don't know if it is ZO compatible. Waiting for the ZO guys to call back. Eric Link to comment Share on other sites More sharing options...
Baller skiinxs Posted July 4, 2016 Baller Share Posted July 4, 2016 You would need a bigger motor box. Link to comment Share on other sites More sharing options...
Members brettmainer Posted July 4, 2016 Members Share Posted July 4, 2016 Not sure if it would fit, but a 6.2L in a 196 would be a lot of fun to drive. Link to comment Share on other sites More sharing options...
Baller ozski Posted July 4, 2016 Baller Share Posted July 4, 2016 With ZO equipped Carbon Pro's and 196's getting cheaper all the time, as cheap as low 20's would put yourself through it? Link to comment Share on other sites More sharing options...
Baller eleeski Posted July 5, 2016 Baller Share Posted July 5, 2016 There are advantages to a smaller boat. Maybe. I want to experiment. Plus the old American Skier has one of the best technical trick wakes. And it needs a new engine anyhow. What is the base of the 5.3? Eric Link to comment Share on other sites More sharing options...
Administrators Horton Posted July 5, 2016 Administrators Share Posted July 5, 2016 @dbutcher I am pretty sure Indmar has 5.7 motors that are ZO ready. You would save a LOT of money that way.

Baller oldjeep Posted July 5, 2016 Baller Share Posted July 5, 2016 Might be able to make it fit, but at a minimum you are looking at a new bellhousing to fit the metric engine to your existing trans and 15K ish? for a turnkey 5.3L crate motor.

Baller_ Jody_Seal Posted July 5, 2016 Baller_ Share Posted July 5, 2016 Sorry trans flange on the Chevy 5.3/6.2 is the same as it has been since 1955. Yes a new generation pcm will fit but keep in mind PCM still does offer non cat Excalibur /ZR6 in a repower application. Installing a new 5.3 or 6.2 H series engine would require a modified engine box and exhaust system. Also keep in mind PCM did their homework when it comes to re powering as in most cases very little if any extra fabricating is in involved and instalation is plug and play.

Baller oldjeep Posted July 5, 2016 Baller Share Posted July 5, 2016 OK, I thought the newer engines like the 5.3L had a couple extra bolts in the bellhousing. Seemed to remember some problems when a guy was swapping one into a Jeep. Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted July 5, 2016 Baller_ Share Posted July 5, 2016 Depends on what came out and what is going in. As for the transmission it remains in the original location. PCM offers chevy to ford adapter mounts on both the sbc and LS. Installing a PCM sbc in place of a indmar I use the indmar mounts. Down angle applications may require omitting the oil drain kit as hull clearance could come into the equation. Link to comment Share on other sites More sharing options...
Baller dbutcher Posted July 13, 2016 Author Baller Share Posted July 13, 2016 I am curious as to why the new engines require a dramatically bigger motor box. According to PCM's website, the 5.3 and 6.2 are only 1/2 inch wider than the 5.7 EX343, 3/10 inches longer than the EX343, but SHORTER in height by over 5 inches. Did Nautique place the new engines higher above the bilge floor? I have only seen one 2016 SN200 with the 5.3, and its motor box clearly looks bigger, especially taller. Why so much taller?

Baller lcgordon Posted July 13, 2016 Baller Share Posted July 13, 2016 @eleeski just wondering what AM skier do you have? I have a 94 tbx. The trick wake is awesome. Slalom is pretty good too. Link to comment Share on other sites More sharing options...
Baller_ DW Posted July 13, 2016 Baller_ Share Posted July 13, 2016 @dbutcher: the engine will bolt right up, it is the rest of the installation that is not a simple carryover. One reason for larger engine box is size of Cats. The GM Powertrain description of each of the configs leads one to see a larger size discrepancy in height / width than the numbers you quote, not sure why but I would assume the PCM numbers should reflect their final product. There is a lot of additional hardware on top of the valve covers compared to the old SBC so that will push width / height out also. If they are making engine box LSA compatible, that is also a reason for increased size as the supercharger sits on top. Link to comment Share on other sites More sharing options...
Baller eleeski Posted July 13, 2016 Baller Share Posted July 13, 2016 @lcgordon My American Skier is a 79. Great trick boat but some spray at shortline slalom. Fixing that is part of the experiment. Your boat is better for slalom and still very good for tricks. Either is worthy of a ZO engine. The American Skier has been reengined once already. The cover didn't fit despite everything nearly the same. The covers are custom engineered to fit perfectly. Small changes interfere with the clearances. Fitting the cover will be a challenge.

Baller dbutcher Posted July 13, 2016 Author Baller Share Posted July 13, 2016 @DW Thank you. I had not looked at GM Marine's website. I knew there had to be a reason for the taller motor box. I would hope that Nautique would use a different motor box for the super charged engines. The lower the motor box is the better it is for skiing (in my opinion). Thanks again.

Baller gcam4 Posted July 14, 2016 Baller Share Posted July 14, 2016 @Jody_Seal will a PCM ZR6 fit into a late 90's 196? Link to comment Share on other sites More sharing options...
Baller bassfooter Posted July 14, 2016 Baller Share Posted July 14, 2016 @eleeski it's been said by guys way smarter than I that there's no replacement for displacement. That American Skier needs a V8. Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted July 14, 2016 Baller_ Share Posted July 14, 2016 @gcam4 yes a non cat zr-6 repower will fit in a bubble back SN. That engine would really be over kill in that hull. A repower Excalibur will run that hull right at 50 MPH. A Better bang for the buck....But get em while you can PCM is only going to provide that engine for another couple years and then only part replacement.

Baller skiinxs Posted July 14, 2016 Baller Share Posted July 14, 2016 The new motor box is the same height as the 6.2, nothing extra. You can see where the inside foam barely touches the top of the engine cover on mine. Link to comment Share on other sites More sharing options...
Baller storm34 Posted July 14, 2016 Baller Share Posted July 14, 2016 @Jody_Seal - depends on what you consider overkill! I spent some time behind the wheel of the CCfan boat (409) and it was by far the most fun to drive of all the newer boats. With any luck our reverse gel 01 SN will have a 409 and ZO in the near future. Link to comment Share on other sites More sharing options...
Baller skiinxs Posted July 14, 2016 Baller Share Posted July 14, 2016 Here is a pic of a 6.2 in my '16. Pretty much fills up the box! Link to comment Share on other sites More sharing options...
Baller gcam4 Posted July 14, 2016 Baller Share Posted July 14, 2016 @Jody_Seal @storm34 I would have to say a ZR6 in a late 90's 196 would be impressive! I will say I would rather have that engine architecture instead of the SBC excalibur. On that same note an excalibur would still be quite nice.

Baller skierjp Posted July 15, 2016 Baller Share Posted July 15, 2016 FYI, 5.3's and 6.2' are the same size. The only quick identifier to tell them apart is the H5 or H6 badge. Link to comment Share on other sites More sharing options...
