2020 MasterCraft ProStar - sneak peek

[theboardingschool]

@Jaypro that's half of the reason we were freaking out. Less worried about a loose hose clamp, then the world finding out which engine we had.

 

And, yes, @markchilcutt the jumpers are loving it. Freddy had our boat for a week and said he had his biggest jump of the year at the time behind it.

 

The best boat just got even better.

[jjackkrash]

I wonder when we get the new GM 6.6 liter gasser (L8T) in a boat.

[SkiSam]

@Cnewbert whoops

[Tkl127]

What are you guys seeing for top speed on the Mastercraft 6.0L and 6.2L at - around sea level? Is it comparable to the Nautique 6.0L and 6.2L?

Asking for those who barefoot and those at altitude who need the bigger motor. Thx!

[eleeski]

I skied @Horton 's new boat today. Slalomed great behind it - but that was probably Elaine's driving (a smooth pull up on an injured back is magic for performance - but the boat was part of that). Lots of people tricked well behind it (I was the vidiot). Boat judging for @Horton was interesting but everyone seemed to ski well behind it. Nice boat. But orange.

 

The only unusual aspect of the boat showed up when helping @Horton hook up his trailer. Something about how his ball needed lubrication kind of made me uncomfortable. (Hope he gets that taken care of right away.) The lights on the trailer say "Mastercraft" as he drove the boat home. Cool little detail.

@eleeski as in he had to grease his ball or his ramp n clamp?

 

As a kid my neighbor towed a ton he showed me an old ball and coupler from before he started greasing, his trailer receiver and hitch ball had essentially worn the front face of the ball flat until the trailer had a "notch" when turning and could be popped up off if you climbed on the back of his boat. Rubbing/friction/sand/rust etc. lapped the thing down.

 

So you shouldn't need grease to force it on but you should 100% get some grease on there.

 

I use one of those rubber ball caps with a blob of white lithium inside and just push it on.

 

 

[eleeski]

@BraceMaker Never take what I say too literally. And always wonder about what @Horton says.

 

What is a "ramp and clamp"? Wait, do I really want to know?

It was nice to get to drive @horton new boat in both Jump and Slalom before he even got to see it. It was probably the best tracking M/C I have driven. I talked to Will about the motor and he confirmed it is a Gen IV 6 liter similar to what the other manufactures have as their base motors.

Sice Horton must still be sleeping...Got that from FB.

Gotta add that the music in the MC Prostar videos is always cool! (Remember 2005 i think ?)

[epnault]

@Tkl127

I can get 50 mph at roughly sea level from my 6.2. Footing was the reason why I got the 6.2.

 

I doubt jumpers will actually use the 6.0 vs 6.2 but I understand the marketing behind it.

[Horton]

@epnault the word I have from the Mastercraft team jumpers is that the 6L is awesome up to about 230 feet. For world record attempts the 6.2 is superior.

[epnault]

@Horton

Makes sense. This looks like a great overall engine (6.0) for the most people and if I had the choice when I was buying it would be hard for me to make sense of ordering a 6.2.

[walleye]

Best hull to date. Please Arn do not change this hull.

[MopedMedicks]

Illmor 6.0: 373 hp

PCM 6.0: 409 hp

 

Why did they design a brand new motor that is 36 hp less than the direct competitor? Thats almost 10% less.

[swc5150]

Could be a wive's tail, but I've read that Ilmor determines their HP differently than PCM, and the differences aren't as far off as the advertised numbers. Teamtalk has some threads on the subject.

[rq0013]

Maybe hp at the prop vs what the engine can produce??

[mastercraftmelbourne]

Ilmor rate there engines at what they are. PCM, Indmar, Malibu all put some Cherries on top.

 

The link below is for the California Air Resource Bureau (CARB). It takes you to reports which list the specific output of the engines CARB has authorized for sale in the state of California. Output is reported in Kilowatts (kw). To

convert kw into horsepower simply multiply the kw rating by 1.34 to see the equivalent horsepower rating.

http://www.arb.ca.gov/msprog/offroad/cert/cert_mfr.php

Once on the website select “Spark Ignited marine engines” and the model year depending on the year of the boat that you are comparing, then click “browse”. From here you can select engine brand and hit “submit” to be taken to

their respective reports. The actual CARB certificate has more detailed information.

ilmor 6.0l - 373Hp (rated), 550torque - 7 year 1000hour warranty

PCM 6.0l - 374Hp (rated), 476torque - 5 year 1000hour warranty

[JaredSmith]

Great information @mastercraftmelbourne

 

[Andre]

Funny.Mastercraft used to be the one that was putting a cherry on their MCX rated at 350HP.

I also doubt the 550 lbs torque quoted 2 post up...and i'm a MC guy! :)

[jjackkrash]

Are any 2020s out yet? Anyone with any seat time in a Prostar with a 6.0l and have any opinions on how it compares to the 5.7l? (sorry if I missed any other threads if this has been discussed elsewhere.)

[mmskiboat]

@jjackkrash yes there have been a few 2020 out and from what I can tell everyone prefers it and also thinks that as a platform it will be more bomb proof over the years.

 

I'm sure some others will chime in with seat time experience.

[RAWSki]

We skied a 2020 at Eden Lake over Thanksgiving. Very nice, I don't know that I noticed a huge difference from the 5.7 but it felt strong and smooth. There was a little issue with some observers putting their feet on the engine box and getting a little rubbing-noise (might have just been an isolated issue).

[Horton]

@jjackkrash I went back and forth between 2019 and 2020 boats this summer. The new 6 L is great. You notice it on deep water starts and top speed. In the course at 34mph I don't find it dramatically different than the 5.7. The open rated 36 mph skier I ski with definitely prefers the 6L for 38 & 39 off.

 

[bigtex2011]

@horton do you know the surface area of the new motor.

[Horton]

@bigtex2011 I'm not sure but I'll ask Jared

[6balls]

@bigtex I think it's such that you can fry 3 eggs on the manifold, an improvement over the 2 egg capacity on the 2019 :)

[skierjp]

Usually GM engines have the torque and HP almost the same.

[lakeho26]

Anyone know the top speed for 6.0l prostar? I know my 5.7 is around 42/43.

[Horton]

@lakeho26 I forget the exact speed my Orange 2020 got up to but it was like 46 - 48 ish. If you want to it go faster you would need to change props. Remember the boats are propped to work between 34 and 36 mph. With a different prop the boat could go a LOT faster.

[mmskiboat]

@lakeho26 When we did a test run we hit 46 and then it stayed put, this was with 3 people in the boat but my wife is not very big, not sure how much gas was in the tank.

[lakeho26]

@Horton @mmskiboat, Thanks we barefoot often a little extra speed is always fun!!! Makes me want upgrade or just engine swap!

 

[jjackkrash]

Those are encouraging reports. 46+ is a good top speed for a ski boat, IMO, as I like a little cushion between 36mph and WFO.

[skierjp]

52 in a 6.2 Ski Nautique with the Hydrogate up

[Horton]

My new one even looks fast. Anyone want to go to Sacromento and get it for me?

[Golfguy]

I have had the 2020 since late August. It has pulled 3 tournaments in the Phoenix area. The 6L engine is naturally stronger, better hole shot etc. More notably it tracks better than ever, and the stearing is tighter. The all around feel is very solid. We talk about drivability, which the MC does well at, but it is really about how the skier likes it. (right?)

[EricW]

In the boat with Freddie on Tues at TBS we hit 45 and climbing quickly headed back to the dock, they have the 6.2 though.

[6balls]

We hit 50 and in a big hurry with my brothers 6.2. That thing was a beast. As mentioned above a 6.2 SN is also a beast.

6.0 TXI is plenty adequate for skiing but not the muscle car feel of the others with 6.2s. In those boats drive your hole shot carefully u can easily overdo it and I LOVE them. Fun boats...more than u need but everything I want!
