Baller UWSkier Posted October 17, 2021 Baller Share Posted October 17, 2021 I'd love a 6.0 in my '01 Response. Getting the old engine out and putting the new one in, I could handle myself with a helper, but all the necessary fabrication and re-wiring I think I'd need a pro. I don't imagine these things are plug-and-play with old wiring harnesses. Link to comment Share on other sites More sharing options...
Yannis Posted October 20, 2021 Share Posted October 20, 2021 MASTERCRAFT PS190 TT year 2004, repower 6.0L , Z/O, same transmition ZF 1.56:1. All skiers are very happy skiing behind it. Link to comment Share on other sites More sharing options...
Baller bassfooter Posted October 21, 2021 Baller Share Posted October 21, 2021 @sgregg We're on Doug's list to do this to our '98 bubble butt, and it can't happen soon enough. The original engine is showing signs of giving up. Would love to see more pix -- dash, throttle handle, etc. It looks great! Link to comment Share on other sites More sharing options...
Baller ski6jones Posted October 22, 2021 Baller Share Posted October 22, 2021 @sgregg did you change to a new prop with the engine upgrade? Link to comment Share on other sites More sharing options...
Baller sgregg Posted October 22, 2021 Baller Share Posted October 22, 2021 @bassfooter - PP to ZO was the only change to the dash, using the original throttle. You will need to fabricate a shim to raise the engine box approx 1.5” - pm me if you would like more info on that @ski6jones - yes, swapped props from a 422 to a 668 Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted October 25, 2021 Author Baller_ Share Posted October 25, 2021 Thought I would give a heads up to anyone considering a repower you may have up to a 12 week wait on delivery of the PowerPlant from order date . Still cheaper then a new tugboat! Link to comment Share on other sites More sharing options...
Baller MDB1056 Posted October 26, 2021 Baller Share Posted October 26, 2021 @bassfooter - or just pull the existing engine and have it rebuilt. Will be like new at a fraction of the cost, and everything reconnects easily. Is ZO really that essential and worth the cost and hassle? Link to comment Share on other sites More sharing options...
Baller RAWSki Posted October 26, 2021 Baller Share Posted October 26, 2021 @MDB1056 Yes and No.... Depends if you want to ski in the 20th or 21st century. Link to comment Share on other sites More sharing options...
Baller MDB1056 Posted October 26, 2021 Baller Share Posted October 26, 2021 @RAWSki - IMO really depends on your level. At very high levels much more of a factor. At lower levels not so much Link to comment Share on other sites More sharing options...
Baller bassfooter Posted October 27, 2021 Baller Share Posted October 27, 2021 @MDB1056 More to it than just ZO. The old engine is a 351 HO, which is carbureted, and we've been running in saltwater with no closed cooling. A rebuild will only get us so far. This new setup gives us modern ignition and fuel delivery, closed cooling and 110 (120?) more horses. I know the boat very well, and my wife and I both love to ski behind it. In fact she's totally into doing this. I'm a lucky guy. Most importantly, @eleeski told me he won't ski with me until I get ZO or a paddlewheel for PP. So there's that.

Baller bassfooter Posted October 29, 2021 Baller Share Posted October 29, 2021 @DW 351 Ford to PCM ZR 409, which is based on a 6.0L GM Vortec. My understanding is that PCM is no longer offering the 350-based Excalibur. Link to comment Share on other sites More sharing options...

Baller Mastercrafter Posted January 18, 2022 Baller Share Posted January 18, 2022 Figured I'd toss in my submission for re-powers. Installing a 2018 Ilmor 5.7 in a 1991 Prostar. End goal is to build it into a 25th Anniversary Stars and Stripes 190 clone.. we'll see. Got the engine running this weekend. It was somewhat involved as it needed a high pressure fuel pump installed into the original tank, as well as TBW throttle/shift control, custom wiring harnesses throughout. Still using analog oil and temp gauges. Far from plug-and-play but now that I've done it, it all makes perfect sense ;) I have a salvage 2016 Prostar doghouse to go on top, because the original was too small in every dimension. I think this will be a fun, unique slalom machine. Link to comment Share on other sites More sharing options...
Baller MDB1056 Posted January 18, 2022 Baller Share Posted January 18, 2022 @Mastercrafter - that's going to be a really fun boat! Great hull. Keep us posted. Link to comment Share on other sites More sharing options...
Baller Hucklefin Posted January 19, 2022 Baller Share Posted January 19, 2022 @Mastercrafter This is amazing. How did you do your driveshaft configuration? Custom cut, or did you just try to manipulate engine position to fit everything? Seems like you'd have to get really lucky for the latter to work for it all to line up and not cause some kind of CG or angle issue. Link to comment Share on other sites More sharing options...
Baller Mastercrafter Posted January 19, 2022 Baller Share Posted January 19, 2022 @Hucklefin I have a couple driveshafts to try but I think I'll need a custom length. The one from the boat is now too long by a couple inches. CG might be an issue but the engine is as far forward as it can be to have the engine box clear the air filter and the ski pylon. Fingers crossed. I supposed I could throw some weight in the bow to balance / level the boat but of course that takes away from my lightweight, low wake, ZO boat project. Engine angle is a non-issue, I've already made sure the shaft couplings mate up flush. Link to comment Share on other sites More sharing options...
Baller Andre Posted January 19, 2022 Baller Share Posted January 19, 2022 @Mastercrafter Cool project! Battery can easily be relocated to under the passenger seat if you need some weight in the front. Should be a fun drive! You're putting ZO off course ? My ski finish in 16.95 but my ass is out of tolerance! Link to comment Share on other sites More sharing options...
Baller_ DW Posted January 20, 2022 Baller_ Share Posted January 20, 2022 Mastercrafter: How much did the engine move? Sounds like it has gone a bit rearward based on your comments. Have you weighed old v new engine setups? Cool project. Link to comment Share on other sites More sharing options...
Baller Mastercrafter Posted January 20, 2022 Baller Share Posted January 20, 2022 @DW the original prop shaft, when installed with the Ilmor, is about 2” too long. I asked a friend to measure between the front of their block and ski pylon on their 1994 190 with a GM 350. Their dimension was 11” and mine is 14.5. This obviously isn’t ideal, plus this engine is way heavier, but without moving the pylon or building a really custom, split motor box, I’m stuck here. Fingers crossed, I guess. If it’s real bad, I could move it forward and go the custom motor box route.. or ski my 2015 Prostar and pull tubes with this.. ha. Other option is moving the battery forward, and maybe even a custom fuel cell up under the bow to get weight out of the back. Link to comment Share on other sites More sharing options...
Baller Hucklefin Posted January 20, 2022 Baller Share Posted January 20, 2022 @Mastercrafter At least you have one thing going for you, that you can just get your current shaft reworked instead of having a custom one built. Have you analyzed if you need to upsize it though, if this was originally a non-HO non-powerslot boat? I don't know the limitations of the 1" shaft. If this was an OEM effort, I'm sure that weight shift would be a huge issue, but given this is a custom project, I'm sure you can find a way to live with the results. Assuming CG location on the engine fore/aft probably isn't much different than original engine (thinking most of the added weight is high on the engine), losing 3.5" to the rear might not be the end of the world.

Baller FSSPCat Posted January 21, 2022 Baller Share Posted January 21, 2022 Not to steal the thread, but it’s been 3 years since I’ve heard anything about the Indmar Ecoboost. I’m genuinely curious if it has been put in a ski boat yet, or just jet boats. Link to comment Share on other sites More sharing options...
Baller storm34 Posted January 21, 2022 Baller Share Posted January 21, 2022 @Hucklefin - Lots of detailed discussion on CorrectCraftFan a few years back with guys building high HP barefoot boats. I don't remember all the details but general consensus was it's not a necessity until you get up into crazy (600+) HP ranges. The 1" shaft shouldn't be an issue with this type of re-power. All new SN's & 200's with the 6.2 run a 1" shaft. Link to comment Share on other sites More sharing options...
Baller chrislandy Posted January 23, 2022 Baller Share Posted January 23, 2022 @Mastercrafter the boat wake is all about balance, too much weight to stern and it will make the wakes larger, you could just put a small amount of weight upfront to counterbalance the larger weight shift from the engine and move the centre of mass back to the original place.

Baller Ski2000 Posted January 24, 2022 Baller Share Posted January 24, 2022 @sgregg or @Jody_Seal Have you guys needed to add any weight in the bow on the bubble butt nautique with added weight of the 409? It’s about 100lbs heavier it looks like over the pro sport engine I pulled out Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted January 24, 2022 Author Baller_ Share Posted January 24, 2022 @Ski2000 Case by case. Even with the gt engines some boats may need extra weight forward. Normally on the bubble butt I would slide 25 pounds under the driver seat as those boats seemed to be passenger side down. Link to comment Share on other sites More sharing options...
Baller sgregg Posted January 24, 2022 Baller Share Posted January 24, 2022 @Ski2000 We swapped out a GT40 and the Series 40 transmission, haven’t felt a need to add weight. Link to comment Share on other sites More sharing options...
Baller Mastercrafter Posted March 22, 2022 Baller Share Posted March 22, 2022 Got the repowered 1991 Prostar in the water for the first time Sunday. The thing rips. We didn't ski it yet, but it gets up to 36 fast and only spins about 3250 RPM there. 48mph top speed with a 14X20 prop, 1.5:1 trans. Despite a full tank of fuel and battery in the back, and the heavy engine moving back a few inches, it handled well with no porpoising. 100lbs lead under observers seat to keep things level with just me in the boat. So far, so good. Excited to ski behind it. https://www.youtube.com/watch?v=GmkWOK5PmWA Link to comment Share on other sites More sharing options...

Baller_ Jody_Seal Posted March 24, 2022 Author Baller_ Share Posted March 24, 2022 @Kelvin Yes pleasurecraft has a great repower program that in most cases allows a new 6.0 non cat to be installed in older non cat boats. Now it is not without extra EPA paperwork but yes the engine is still available. Pleasurecraft does not offer a catalytic engine that has dual exhaust. That becomes a big and costly problem on dual exhaust boats. This engine is going in a very nice old Hydrodyne. Link to comment Share on other sites More sharing options...

Baller Mastercrafter Posted March 26, 2022 Baller Share Posted March 26, 2022 @Jody_Seal - what do those PCM engines require for fuel and throttle? Are all the new ZR4 engines you get closed-cooled? Does the engine mounted pump draw right from a tank pickup, or is there a low pressure pump to move fuel to the high pressure pump on the engine? Is the throttle control completely DBW or does a throttle cable connect to a device on the engine that then converts it do “DBW” With this Ilmor repower I had close to $2k in a fuel pump and DBW throttle/shift control which kinda sucks.

Baller_ Jody_Seal Posted March 26, 2022 Author Baller_ Share Posted March 26, 2022 @Mastercrafter Yes closed cooled. They are DBW however Potentiometer is mounted on the engine, mechanical cable from throttle control the Potentiometer. Now if one wants a electronic throttle installed it can be done. Yes the engine comes with a FCC mounted on the engine as well as remote oil filter. They will run on piss water but mid grade and above recommended Link to comment Share on other sites More sharing options...
Baller Mastercrafter Posted March 26, 2022 Baller Share Posted March 26, 2022 @Jody_Seal , nice- thanks for the info. Better/easier package for repower, that’s for sure.
