I guess Supply and Demand over came the Economies of Scale???

Yes, the 21 PX and the ST3 hulls use the same sponsons. I have not heard if there are the same benefits/improvements noticed with the...

The Sea Doo 300 has Normal and Sport modes for the ECU to change mapping for performance gains. Do the Yamaha SVHO series have mode selection in their ECM? I have noticed that you can limit the top...

I would like to know more about the torque limiter on the 300......

Ok, love the educational opportunities on GH.

I know what a torque limiter does on turbine aircraft engines, but how does it work on our 300s? Is there actually a sensor or is it algorithmic? I...

Looking forward to your performance review and numbers. With the 67 pound weight drop, the numbers should be the best of any ski available. Of course adding the additional fuel will net you...

Unfortunately, you do remove oils and the plastic does become more brittle. The other problem, is if you get it too hot, you will get wet spots like the three on the nose. Gotta keep the gun moving...

Since you are in SoCal, contact Fritz at Shadow Trailers.

What's the latest on your thoughts? I may sell my 18 to move to the 21 also.

What does the bone stock 8300 do besides removing the speed limiter? Does it change fuel and ignition mapping?

That is certainly what one would believe since so many use the bypass without a can. I have always had a can on my RXP 300, but never had any oil in it until I removed the speed limiter. The...

What code are you getting with the maint light?

I don't think Fizzle is making any cans. Riva still offers their can for SD, but I don't see a can offered for the Yammi.

Haven't seen too many Yamahas with cans, where do they mount? Who sells cans for Yamaha? It looks like most places stopped selling them. Jerry, does GH sell a can for Yamahas?

I have noticed that some folks run a "breather kit" to reroute the crankcase fumes to the bilge, but there is no catch can. If the SVHO doesn't produce any oil, why the bypass? If the oil vapors...

I'm still waiting to hear South Ga answer to K's question from 10-15-20. It had opportunity to be educational........

Does the 2021 GP1800 still use a mid carrier bearing?

Is the zerk usable or do you need to fab an extension?

Three and Four year warranties are very common. The current offer of two is the shortest that BRP has offered in awhile. The longest that BRP will offer/sell is 5 years.

maybe to sell short blocks....

Harry has done my machine work since 1994. I enjoyed visiting his shop a few years ago. He is a top 2 stroke expert. We have all seen too many Yamaha 1200 engines blow up totally stock. I bought...

You most likely will need to pressure test the head to see where the crack is.

I did not know that the Maptuner X provided diagnostic info and key programming. That's awesome.

Thanks K, appreciate the specific info.
Great to know that the hull and chain issues are in the past. The head is a concern. Has Yamaha ever stated a cause, metallurgy, cooling? Have there been...

Looking for some updated info from the Yamaha forums.
What year were these issues corrected?
Cracked hulls around the ride plate mounting area
Broken timing chains
Cylinder head cracks

great comparison shot, thanks

There are hundreds of cans out there and this has never been reported than I know of...
I can't think of any reason for what you are describing to occur. What did RIVA tell you?
