Just wondering if any of you have heard of the new 215 SCIC's having a break-in chip that retards timing and reduction in hp (30%)? I'm told this chip doesn't hand over the ponies till 10-12 hours of running time. I hope this is true because my performance has been less then stellar. I have researched proper breakin procedures and feel that all mating surfaces (pistons, cylinders, rings etc) should be ready to go for wot useage. Maybe some dealer members can shine some light on this. In the meantime, my best friend is a factory sponsored BRP racer (snowcross) and is going to check with the factory to see if there is any truth to this.

The reason I bring this up is I wonder if the boats used in all the mags and online tests have been running with this chip?..crosses fingers hoping for more performance

What RPM's are you running at WOT now? If you are between 7750 and 8000 with the SCIC 4-tec, that's all you are going to get with your setup (stock impeller etc). I don't think there is any "chip" or special break-in setting. My 4-tec enabled Speedster hit 7300RPM quickly while plaining at 2 hours of run-time (not getting limited other than by my right arm). That's all I will get with the standard 4-tec.

yuji i have heard this also - basically my dealer said that make sure it comes back for its 10 hr service as he said you wont believe the enhanced performance once weve serviced it, there must be some form of restrictor fitted, it doesnt necesarily mean that you wont get full rpm - i think maybe they de-restrict the supercharger by removing ' a gate' or something which aloows it to breathe better, which would enhance performance, so i too am lookingforward to its 10hr service and seeing the difference - i am sure all test boats would have less than 10 hrs on them.

It will be interesting to hear back after your 10 hour service. It seems to me that max RPM=max performance when we are talking about jet drives. I guess how fast it gets to max RPM would make a difference in hole-shot, but not in top speed.
Perhaps this is specific to the SCIC models, my dealer told me the 10 hour checkup was optional, I could just look things over myself, but I don't have the intercooler or super charger.

incidentally - i have read that some people can hear the supercharger - but i am unable to hear mine - which also lends credibility to the fact that it might not be working to max rpm itself even tho the engine revs to max rpm - w8 and see

[kman10274]

my scic runs the same after 10 hour service . I can hear the supercharger from day one .

[Yuji]

Yeah...the supercharger is fully operational...I'm referring to timing and rev limitation via a chip. Yes, I could hear my SC from day one. How many hours do you have kman? It's supposed to turn over at 10-12 hours...Did you have your first service and verify your hours via "Buds"? Either way, we'll see...i've got 4-6 hours to go till i find out.

[thumper]

what doo your sc's sound like???

[keviseeb]

YES.....there is a computer controlled break in period that retards timing and increases fuel flow for the first 5 hours. After that the timing and fuel flow are returned to normal during the next five hours. It is COMPLETELY automatic, the dealer does nothing to alter or improve break-in during or after 10 hours. The RECOMMENDED 10 hour service is NOT mandatory to maintain warranty nor will it help or hurt the eventual performance of the engine.

Kevinseeb,

Would this explain the somewhat hard starting of the engine while hot (retarded timing)? I had a good day on the water today. The coolant level stopped dropping today (I added about a quart and a half over the first three hours). Other than taking a few tries to start when hot, the boat ran great today.

half an hour away from 5 hours - ooh cant w8.

Wow, thanks for the information. Do you have any published data that references that? I'm just curious to know how much timing is retarded and what %DC the injectors run when this happens over std. Guess I'll find out next weekend on the seat-of-the-pants feel.

I just took delivery of my 2004 Speedster 200 this weekend and am quite pleased with the performance. I am interested to learn more about this 5 hr break in period. My dealer could not tell me what difference I will see.
I am running approx 7300 rpm and speedo showing max. 50 MPH on short hold(break in ).
Can you offer any more details on what I might see after the 5 HR chip expires on the 04 Speedster 310HP .

Thanks in advance!

[keviseeb]

Here are the facts regarding the automatic break-in feature of the 215 HP BVIC engine (supercharged intercooled) according to the Seadoo 2005 Technical Update book given to all Seadoo jet boat and pwc dealers each year. The timing is retarded 6 degrees and there is 5% more fuel, that happens during the first 2 hours. During the next 2 to 5 hours the engine returns to normal settings. Total break in should happen within the first 5 to 7 hours. The break-in ONLY APPLIES TO THE SCIC type engine. The 185 HP and 155 HP engines DO NOT have any computer generated procedures. Also remember that you still have to handle the break-in RPM yourself, i.e. varying RPM and not staying at any given RPM for more than 20 or 30 seconds until after the first couple of tanks of fuel. Also, again ONLY for SCIC engines, remember that the spark knock sensor will retard timing depending upon the fuel used. Premium is the best way to go.

keviseeb - what is the recommended octane rating for the fuel is it 90 or 95?

[Yuji]

Here in Canada our Premium is 91 Octane. I would say that is the recommendation Thumper. Higher octane is not always better when it comes to motor performance...The higher the number the less voloatile the fuel is, which then requires more compression to acheive the desired burn and hp #'s. Running 95 octane may give you sound mind, resist pre-detonation etc.. but I don't think it will give you any more peformance that the 91octane would imo.

Someone say this on a other forum : << Just had a dealer tell me that the new 2005 Sea Doo Wake (GTX 155 hp) we are looking at buying requires use of the rpm limiter (training) key for the first 10 hours of use. This is supposedly to provide a better break-in period. >>

Is that true?

I believe you have to purchase the learning/training key. The dealer said it was offered for my boat (05' Sportster 4-TEC SCIC) in case I wanted to let a friend borrow it or teach a driver... the key can be programmed to govern to a specific mph.

[thumper]

i asked about the learning key - and was told - dont be such a girl

[Pyrock]

I believe that you will only benefit from higher octane fuel (higher than 91) if you increase boost. This would prevent detonation at higher boost levels.

Regarding break-in...so the key is to vary the RPM's and not stay at any specific RPM for more than 20-30 seconds at a time? Any more advice on break in?

Thanks
