SeaDoo Wake 155 Engine Locked Due to Detonation + Rotax 155 Motor Rebuild by Calas Performance

[@jordigrau3625]

I love this videos when we discover the fault together with you. Mechanical vídeos are the best one. Thank you.

[@superk4562]

Hey thanks for the tip on identifying detonation by looking at the upper connecting rod big-end bearing. I've got a 2017 GTR 230 that melted the #1 cylinder piston, and it burned through the cylinder liner, so I have a new block (and a bunch of other new parts) here at my shop. Sure enough, each of the three upper connecting rod bearings is more polished than the lower bearings. Yea, I was running 87 octane gas in accordance with my owner's manual. I won't be doing that anymore. 56 hours on the engine. and now a $3,500.00 repair bill ... and that's doing the rebuild myself!

this man right here is fearless! best of the best love the content and thanks so much for sharing it all with us. your a wonderful person

[@Tassie1966]

Great video keep up the good work I have 2015 GTX 155 which I have had from new 15 months ago number 2 piston failed destroying the block is had 136 hours on the motor always been well maintained regular serviced and never got a hard time I was running 91 fuel here in Australia which I think is equal to your 87 I have since replace the motor and the mechanic that cleaned my injectors told me never to run 91 always 98 = you're 93 since doing that my ski is running and performing better than it has ever done before and it only cost me about $5 more a tank to fill.

[@raymondanderson9020]

many hours but done correctly nice work carlas.

[@brendenbopery8673]

Wow, so glad I saw this video! I just purchased a GTi 130 and spark Trixx and they told me 87 in both as well…I will be switching to the 93 for sure!

[@JackJones-fg1jx]

Go by the owners manual recommendations. These engineers fine tuned the engine for a specific octane.

[@DessiLu14]

When running pump gas, also make sure to run some kind of fuel stabilizer in your gas to prevent issues when the jetski is sitting not being used. I know rec fuel has a lower octane rating of 90. However, it contains no ethanol. Maybe using a octane booster with the rec fuel will be the best

[@Boostedzc]

Allot of great information!! Thanks for sharing. 😊

[@bonzai5050]

Mister Calas Wow super you show us what' goin on to the top bearing rod ( when pre detonation ) very bad for engine

[@raymondanderson9020]

i like it cranks fast.

[@joeanthony7942]

So informative! Awesome video

[@johnnycaylor7837]

Great video brotha. Awesome content

[@jayhaveyable]

Great info. Sometimes you have to ignore the owners manual for the good of the engine ... I will never consider 87 octane...cost of fuel is not an issue if you can afford these machines. Recommendations of 87 in the owner's manual and for most online forums is an issue.. thanks again

[@JackJones-fg1jx]

Millions of dollars spent on engineers and fine tuning the engine for a specific octane. Go by the manual and not listen to couch mechanics in forums

I have a 2022 sea doo with the 1630 ACE 4 STROKE with 15hrs on it, I've been using Reg. gas, should I start using Prem. instead on this engine?

[@calasworld]

Yes

[@alexandermontero6386]

Hi calas, I would like to know why my Sea Doo Supercharger releases a lot of white smoke from the exhaust and possible causes?

[@mashdatrashvideos2831]

These are super reliable engines, I wonder what caused this problem in the first place, maintenance? hard riding?

[@DessiLu14]

Detonation from using 87 octane fuel will cause this.

[@calasworld]

It’s a high compression motor it needs premium fuel. The dealer will tell you cheap gas I think because it’s a good sales pitch

[@mashdatrashvideos2831]

@@calasworld wow, I never knew, I have a 2019 fish pro with the 155 which I take far offshore and maintain it religiously but I use usually 87 ( only gas at the dock) usually with a fuel additive, definitely gonna switch. Thanks for the videos

[@IHadToMakeThisAccount]

did you like not watch the video he literally says what caused in it? lol

[@mashdatrashvideos2831]

@@IHadToMakeThisAccount thanks genius, I was curious if there were other factors since its not a common problem

[@bigblock1968impala]

I tell all my customers all seadoos use high octane pump fuel, 98 here in Aus

[@brucecooley4170]

So about the pump failure, older Seadoo pumps used gear oil wet bath style lubrication, but newer pumps use grease only. Is one or the other a better? My experience is freshwater only and in 20 years never had a failure with gear oil pump. What is your recommended approach to maintenance of pump? Maintenance depend on wether its saltwater?

[@calasworld]

Yes salt water is worse in salt water. They typically last between 3 to 5 years and you have to rebuild the whole pump.

[@bradymacaraig6638]

Thanks for the education! Kind of wondering: was there any metal shavings in the oil filter? kind of curious to see if that could be a quicker way to check if crank/rod bearings decided to "see themselves out".

[@calasworld]

Yes

[@michaeljamieson4639]

Can anyone tell me the angle between cylinders on compression stroke 😂 setting up haltech and can't find much info😊

[@JonathanF101185]

How did you know the engine block needed changing? I have a thrust bearing that was scratched up due to the jet thrust bearing pushing the driveshaft back into the engine on a 2017 seadoo GTR 230. It seems the only damage is to the thrust bearing, no discoloration of the piston or metal shards present, thoughts? Does it 100% need a crankshaft and a block?

[@calasworld]

You have to inspect your parts and you will physically see the damage

[@Slowrxt300]

So a 2021 GTI 170 should run 93 then ?

[@محمد-ش7ك6ل]

شكرا❤

[@Deighty181]

Do you always have to replace the carbon seal if you take the driveshaft off?

[@calasworld]

No, only if it’s bad or pitted or scratched , or if you knew that it was leaking water

[@Deighty181]

@@calasworld you are the best!

[@duffydorner9968]

I love your videos!! I have learned a lot from you thank you for that. I have 2 2022 seadoo’s GTI 170 SE. I have always ran 93 octane in them. They seadoo dealer said that I’m nuts for running that expensive fuel in them. I’m from the Midwest so fuel up here last year was very expensive. Why would the dealer tell me that he said they were designer run on 87 octane. I just figured its a high revving engine. Why wouldn’t you run the better fuel through it ?

[@calasworld]

I think it’s a sales pitch

[@calasworld]

You can’t tune compression it’s a high compression motor

[@HectorGarcia-k9u]

Hi, where are you located

[@petersmoore1]

Should 93 also be used in supercharged motors?

[@DessiLu14]

Yes. You need 93 octane on everything

[@calasworld]

Yes

[@johnnyringo2550]

Mr. Calas ,,, my mechanic has recommended me using ethanol free gas in my 07 RXT , it's been modified a little 👍🏼 , wondering your thoughts on the ethanol free gas , also great video , I love it when "" we "" pull a motor together 😃 . Your #1 fan from Austin Texas 🇨🇱 👍🏼 Sea Doo Life

[@calasworld]

Ethanol free gas for recreational application. It’s perfect now remember you need to have at least 91 octane

[@mikebryantrealtor9302]

I have this model. Curious about why BRP recommends 87 Octane?? I've done this since I purchased it earlier this year. But you make a compelling case for 93. Just baffled about the MFG recommendation there.

[@JackJones-fg1jx]

Go by what the engineers recommend in the manual

[@3akoscielski]

Does this apply to the 170HP engine (1630 ACE) as well? Why would the manual suggest 87 Octane if that octane level isn't high enough?

[@calasworld]

The only thing I can think of it’s a sales pitch because it’s supposed to be an economic Jetski. just my opinion

[@JackJones-fg1jx]

Because millions of dollars have been spent on research and engineers fine tuning the engine to run on 87 octane.

[@carloscorrea7029]

Is it OK to put 93 Oct gas on a 2007 yamaha ho, no hvsho?

[@calasworld]

Yes 93 oct

[@4defy772]

Very curious, how long would you say a 2013 Sea-Doo Wake 155 engine would last before a rebuild? Well maintained.

[@calasworld]

I have a Rxtx 260 with 700+ hours in for maintenance at my shop now. It’s all in the maintenance.

[@jasonhudgins9437]

What type of maintenance do you recommend for us do it yourselfers ?

[@JetSkiSuper7]

I have a Kawasaki SX-R and I'm blown away that the ski manufactures do NOT have a pump fix. Under no circumstance should a pump failure destroy an engine. It took the aftermarket (Kawasaki Performance) to come up with a solution to prevent engine damage on the OEM pumps. It's a pretty simple shaft redesign that prevents catastrophic failure.

[@MrSuperchargedv8]

Hello, im in the market for a jetski that I will be using in saltwater. I want a full-size performance model that I can upgrade, modify, and hopefully get something thats reliable even if I have to put some money into it. What used jetski will fit that description? Im new to jet skis so any help or guidance would be greatly appreciated.

[@IHadToMakeThisAccount]

whats a ball park for a job like this? 3K?

[@calasworld]

Yeah, somewhere in the ballpark depending on what needs to be changed

[@thecaveman4383]

My state only has 91 premium gas what do I do?

[@calasworld]

That is pretty close to 93. Just don’t go as aggressive on the timing.

[@cap2c484]

I like to run ethanol free and what I find locally is usually 90 octane. What is the best product to get it to 93?

[@DessiLu14]

I'd recommend an octane booster.
