Administrators Horton Posted July 8, 2019 Administrators Share Posted July 8, 2019 “MasterCraft has spent 3 years working with Ilmor developing and refining the new Gen 5 six liter, and we couldn’t be more excited about its release as the standard motor in the 2020 ProStar. Throughout the validation process we saw performance gains that absolutely raised the bar for the slalom pull as well as an unbelievable jump and trick pull. This marriage of motor and machine has brought the ProStar to a performance level that will continue to clarify why the ProStar is the the best skiing, best performing ski boat on the market.” Freddy Krueger "I've been training with the 6.0 since last year. It's led to my most successful start to year the since I started in Pro skiing. The engine is strong where you need, responsive but crucially not overly aggressive in the wrong places."

ScotChipman1 Posted July 9, 2019 Share Posted July 9, 2019 Is this new engine next generation like the 5.3 (H5) and 6.2 (H6) or old technology like the current 6.0 that you can get in a Malibu or Nautique? Link to comment Share on other sites More sharing options...
Baller Keith_Menard Posted July 9, 2019 Baller Share Posted July 9, 2019 @ScotChipman1 I was wondering the same thing...the 6.0 I have in my 04 Denali was an AWESOME engine...but the 6.2 I have in my new Denali is head and shoulders above it.

Baller UWSkier Posted July 9, 2019 Baller Share Posted July 9, 2019 GM L96 6.0L is sequential fuel injection and iron block. H5 and H6 are direct injected and aluminum blocks. Ilmor also has 5.3 and 6.2L engines. Not sure if those are optional in the Prostar as they're lighter by a good bit. Still though, 6.0L as a base engine replacing the old 5.7 is nice.

Baller vtmecheng Posted July 9, 2019 Baller Share Posted July 9, 2019 I had the pleasure of skiing behind a 2020 Prostar last week at Peace, Love, and Waterskiing with Corey Vaughn. He has a shorter setup on one side and the engine got me up and to speed in plenty of time. Even I noticed how nice it skied and I'm a crap skier. At long line 30 mph I hardly noticed there was a wake. Also, my wife was in the boat and made a couple comments about how nice it is. Link to comment Share on other sites More sharing options...

Baller UWSkier Posted July 9, 2019 Baller Share Posted July 9, 2019 something seems off. GM Gen 5 are only 5.3L and 6.2L. There's also supposedly a 6.6L for 2020. From what I can find, GM has never produced a Gen 5 6.0L engine. LINK Link to comment Share on other sites More sharing options...
Baller Roger Posted July 9, 2019 Baller Share Posted July 9, 2019 @Horton - Does this engine idle instantly like the other two boats (MB and CC)? The one thing that sometimes annoys me with my ProStar is waiting for the engine to idle down on initial start-up. Still love my (16) ProStar! Edited to add: Okay, watched the video, idles down faster than my current boat at least... Link to comment Share on other sites More sharing options...

SkiSam Posted July 9, 2019 Share Posted July 9, 2019 @Horton The boat definitely looks nice, can't wait to see what you think of it. @Roger I think the quick idle is just because it was warmed up already from running it around the lake. Still idles pretty quickly from cold though in my somewhat limited experience. Link to comment Share on other sites More sharing options...

Baller Dirt Posted July 10, 2019 Baller Share Posted July 10, 2019 Is the hull the same? I am wondering what the suface area is on it, especially compared to the other boats. Why a 6.0? It was the best engine in the 200. Link to comment Share on other sites More sharing options...
Baller JackQ Posted July 10, 2019 Baller Share Posted July 10, 2019 I realize that the ancillaries (alternator, raw water pump, exhaust manifolds, etc) are different but typically at the end of the day the differences between marinizers or is it marinizors, beyond ancillaries is minimal.

Baller Gar Posted July 10, 2019 Baller Share Posted July 10, 2019 Looks like a great design easy to access a lot of things but is that a brace on the raw water pump if so looks like it needs some more meat. Link to comment Share on other sites More sharing options...
Administrators Horton Posted July 10, 2019 Author Administrators Share Posted July 10, 2019 @dirt the hull unchanged. I know of no other changes besides under the engine box.

Baller DangerBoy Posted July 10, 2019 Baller Share Posted July 10, 2019 @UWSkier Is it possible they may be using one of those other blocks like the 6.2 and just stroking it a little differently to get the 6.0 displacement rating? Have a look at the bore dimensions on the 6.2:L Gen 5 engine and on the Ilmor 6.0 L and see how they compare. It would cost way too much to build a different block for this application so methinks they're probably using an existing block and stroking it a little differently to get the different displacement number. 0.2 L is only about 12 cu in so spread out over 8 cylinders you don't have to decrease the stroke distance all that much to get a 6.2 L down to 6.0. Maybe others could chime in here. Does that sound plausible? Link to comment Share on other sites More sharing options...
ScotChipman1 Posted July 10, 2019 Share Posted July 10, 2019 The only thing I don't like is the extra blower that can be a little annoying. If the air intake was lower in the engine compartment and/or more fresh air was forced into the engine compartment you likely would not need the extra blower to keep the air intake temperature down.

Baller jjackkrash Posted July 10, 2019 Baller Share Posted July 10, 2019 It is nice to see an upgraded base engine over the 5.7l (even if its not a direct injected engine like the 5.3 or the 6.2). https://www.ilmor.com/Marine/Mastercraft-Inboard/60L-MPI Link to comment Share on other sites More sharing options...
Baller theboardingschool Posted July 10, 2019 Baller Share Posted July 10, 2019 The engine is amazing! We’ve had the first production one in our boat at The Boarding School since October. 400 hours on it now. No issues. Very strong and smooth. The Zero Off is really dialed in as well. @FWinter can attest. Y’all are going to be very happy with this one. I’m just happy I don’t have to go in to panic mode when a student opens our engine box anymore. Link to comment Share on other sites More sharing options...

Baller BraceMaker Posted July 10, 2019 Baller Share Posted July 10, 2019 @ScotChipman1 would be nice to see a real pulse width modulated fan that could run based on actual ventilation needs of the engine.

Baller bishop8950 Posted July 10, 2019 Baller Share Posted July 10, 2019 @Horton when does yours arrive? I can’t wait to ski it. I have always felt the ProStar would be better (already great) with a bit more power. Link to comment Share on other sites More sharing options...
Baller UWSkier Posted July 10, 2019 Baller Share Posted July 10, 2019 @DangerBoy this one is a Gen IV block. It's iron and it's MPI, not DI. Very nice upgrade from the 5.7 as the base engine and should be bulletproof. Would be interesting to ski it back to back with a Gen V and see if the weight makes a difference. Gen V engine should be about 100 lbs lighter. Link to comment Share on other sites More sharing options...
Baller Cnewbert Posted July 11, 2019 Baller Share Posted July 11, 2019 @jayski, the MSR base price of the 2019 Prostar was $80,950. Action Water Sports priced me out a new 2020 and its base price was $84,280. So, a $3,330 bump. Part inflation I suppose. But the greater part of the price hike is likely the new engine.

Baller Cnewbert Posted July 11, 2019 Baller Share Posted July 11, 2019 @LoopSki, remember, those are the MSRP. Nobody pays that, or anything close to it. My quote from Action for a new boat/trailer with options came out to about 24% off the MSRP. That would make the base price for the 2020 with the new 6.0L 373HP engine $64,052 at that discount rate, or about $2,530 more than the 2019 at that same discount. That seems pretty reasonable for the bigger engine. Link to comment Share on other sites More sharing options...

Baller markchilcutt Posted July 11, 2019 Baller Share Posted July 11, 2019 I was told the top jumpers are loving the new power plant and hitting 230 foot jumps behind it. No more option for the 5.3 or the 5.7. You get a 6.0 or 6.2. Could be a long winter waiting on a 2020! Link to comment Share on other sites More sharing options...

Members Greg Banish Posted July 11, 2019 Members Share Posted July 11, 2019 @Horton "MPI" = Multi Port Injection (NOT a GenV DI engine). You can see the fuel rail crossover above the middle of the intake manifold in the pictures, confirming that it's based on the older (GenIV) engine. Still, not a bad engine though. They have proven super durable in their OEM truck applications over the years. Link to comment Share on other sites More sharing options...

SkiSam Posted July 11, 2019 Share Posted July 11, 2019 @Cnewbert The difference between MSRP and actual price chops a good bit off, plus the inflation from '18 to '19 is ~2.5% so it's really a negligible bump in price. Link to comment Share on other sites More sharing options...
