On the flipside of that, a jet pontoon made or FRP type materials is a perfect step up/companion to the PWCs that Yamaha already sells. Yamaha can convert PWC buyers into boat buyers and sell their engine plus a boat, as opposed to losing it to seadoo entirely. Sure, they might go to a runabout style yammie, they might go to a pontoon with a yammie prop motor... But they'd be a more valuable customer if they went to a yammie deck boat.
I guess the difference in my eyes is I don't see people upgrading from a PWC to "any" pontoon. Especially those who now have kids will not want to mess with props, etc for their family boats. But they also may not find the 19 or 21 foot runabout spacious enough. Taking the yamaha jet powerplants and placing it in a deck boat or pontoon type craft makes a TON of sense.
The age of the buyer has more to do with going from a PWC to a Pontoon. A younger buyer or PWC owner, will never look for the features an experienced boat owner is looking for. So it's a good stepping stone.
After owning multiple Waverunners, boats and now our 242LS, I could see myself buying a tritoon next. The only issue keeping from that, and pushing me towards a jet powered pontoon would be the shallow channel we have to navigate to get onto our lake.
But the prop value proposition is much greater than the supposed safety of a jet. I can say that easily that this "no prop feature" is blown way out of proportion by jet boat builders and owners. When we were growing up, you learned real quick, if the motor is running, you are not in the water. If you are swimming, diving, or climbing in, you avoided the prop. Easy enough. Don't be stupid. Yup, a few knocked their knees or head, but nobody died, like the marketing would make one believe.
On the flipside, I do love how an inboard, or jet drive frees up the stern for an entertaining space, and we miss it on the Yamaha powered tritoon on our dock to this day. So we both like the stern for different reasons. Would I replace a Yamaha powered tritoon for a Yamaha jet powered tritoon, hell no. We can putt putt all day long on half the fuel, and a fraction of the noise. And anyone buying a toon for those purposes (mind the generation gap) will not give up quiet rides for an open stern.
As per the other thread with the ecoboost powered jet toon, that's the ticket. A nice quiet turbocharged 6 cylinder giving me the shallow draft of the jet pump and the potential open stern space, without the noise of a Yamaha jet. That's way more ideal than anything Yamaha is putting out today. Yamaha could do this with their current motors, but they will have to identify their market before hand. If they want to build a seadoo killer, they could do it now. But if they want to compete with the Benningtons of the world, they better wrap the engine compartment with more kilmat than any of us have ever seen.
And don't get me wrong, I have no issues with the noise of our pair of 1.8ltr engines. But it is no replacement for a Yamaha outboard, or one of those ecoboost power plants.
You nailed it when you said the Seadoo toon is a stepping stone for the younger generation of boaters. As any experienced boater would never buy one. And thus the answer to so many folks questions about the SeaDoo. "why is it made so cheap, so small, no luxury features?" Because folks buying a boat for luxury cruising will never buy a plastic boat.
