Re: Yamaha jet boats- worthy?

Really like the look of the Yamahas. As others have said they really found a way to make incredibly roomy boats. They all have large beams which are carried well forward & the rear area/swim platform really is unique... No other manufacturer has anything like it. The fact that engine, hull, well everything are all made by Yamaha is a definite plus.... Gotta make for a simpler situation where warranty claims &/or other servicing is concerned. I'd have one with absolutely no hesitation.

Re: Yamaha jet boats- worthy?

I considered a yamaha while we were looking for our last boat and I wanted to pursue them more but the admiral put a nix on that. Her reason was real estate, not enough lay out room. We were looking at the sx 230 ho and I loved the idea of the rear facing seats but it eliminated the "princess pad" and I want her to enjoy her time out as much as I do we ended up back with an i/o. But I still want to check out them yamahas and see what they're about.

Re: Yamaha jet boats- worthy?

A couple other questions about these Yamaha jets.
I never thought about it before, but what about trim? Are they just not needed with a jet because of the thrust nature of propulsion? ( ie no propeller trying to screw itself underneath the boat, or intake suction holding things down?)
Secondly, to flush salt water out of them is it done via a hose connector on the engine? Does that then flush the drive pump?? I figured muffs wasn't an option LOL

They sometimes have trim, just like other I/O's. Trim will vary by model/brand, though, just like with jet skis.

The hose connector is usually past the pump, so it only flushes the engine/exhaust. Depending on whether it is closed or open-cooled, it may only flush the exhaust/heat exchanger. There isn't much of anything to flush on the drive pump, so no real worries there, you can just spray the impeller down from the intake grates/pump nozzle if you like.

I would avoid a head. Usually most marinas have bathrooms. I have owned my cuddy for a few years and we haven't used the head yet. We even have a pump out head for our boat. Doesn't seem worth it when you can pee in the water or if their is a bathroom near by.

Yea I'm dubious about the value of a head actually, but if it turns out not to be of any real use it at least would make a great storage bin! ( ie possibly a couple of folding bicycles would fit in there?

Re: Yamaha jet boats- worthy?

Some feedback please regarding handling from those familiar with jets vs I/Os .

I just got back from a 3 day weekend on the the ICW around the St Augustine with my Regal 2000. Had a blast! :) I only saw two Yamaha jet boats all weekend out of hundreds :suspicious: but at least 80% of the boats were fishing rigs. I ran over a fair amount of floating reeds and weeds that had been lifted by the tide and wondered if they would be an issue if I were in a jet.

But anyways, several times when overtaking or being passed by others my I/O had the occasional lurid "surf the wake" and/or yaw feeling that I'm familiar with when crossing a 2-3' wake at about 20-30 degrees- a little unsettling but predictably manageable with steering into it when I feel the pull. Yes, I could always turn to attack the wake at a less acute angle, but in somewhat narrow passages that takes up a lot of real estate.

So how do jet boats handle in situations like this wake crossing slide/surf/yaw relative to I/Os ? Is a more aggressive angle of approach a must for jets? My guess is that without the "vane" effect of the out-drive the unsettling feeling would be magnified.

Re: Yamaha jet boats- worthy?

The "vane" effect is more of a function of the hull, than the little bit of outdrive in the water. There wouldn't likely be much difference in the way the boat handles that situation, assuming the same size boat as yours.

Re: Yamaha jet boats- worthy?

The bigger the waves, wakes, etc. the worse the ride will be in a jet compared to your Regal. They are more suited to inland lakes with calmer conditions. A jet like the Yammy will handle it, but with much less grace than your boat would.

Re: Yamaha jet boats- worthy?

I'll admit this is going to be a biased response. This is coming from someone who owned 10 pwc over the years, one Monterey I/O, and use to work for a Yamaha dealership. I absolutely love my 2012 Yamaha 242 LS. When I went to the boat show this year there wasn't one boat within the same size range that I would have rather had.

My boat often turns heads and I always get very positive comments from previous I/O owners after being out on it. It's a very sporty handling boat, impressive holeshot, tons of pulling power (I use half throttle to pull wake boarders up otherwise I'd rip their arms off), and it looks great IMO. I love the rear seats that are inches from the water. And the absolute best thing about a Yamaha jet is the next to no maintenance which means I keep more money in my wallet (and I do all my own work). It's also much easier to work on than my previous I/O. I also like to think of Yamaha as the Honda or Toyota on the water... Very reliable!

There are negatives. It can suck something up into the pump. Rarely will this ever cause any damage. It's just an inconvenience but it only happened to me once out of 32 outings last season. There isn't any trim but I've never felt like I needed it. Handling is very different at low speed than an I/O but I now feel like its an advantage not a disadvantage. You get use to it very quickly and the new jets are just as easy to drive as an I/O... Just a different feel. They do suck down a little more gas, but not much. I burn roughly 10gph cruising at 5200rpms and around 27mph. While driving they don't track as easily as an I/O since there isn't anything hanging in the water to add stability. Again y get use to this.

Overall I'm very happy with my boat. They're not for everyone... But I don't mind that! I like having something a little different. For me it's the right boat and I won't be switching back to an I/O any time soon!

Re: Yamaha jet boats- worthy?

Well I finally got around to visiting the Yamaha dealer this last weekend, and was sadly disappointed. The following is not intended as a condemnation of the brand, but simply my observations. And to any of the Yamaha owners, my apologies if I made incorrect observations or am just off base all together. Fell free to enlighten me :) FWIW my modest benchmark is an 07 Regal 2000, and while far from yacht quality and the second smallest of the Regal line up, I have been pretty happy with it's fit, finish, QC and reliability. And yes, I've studied several brands over the years, albeit on the smaller end of the scale.

Yamaha positives-
Aesthetics! The Yamahas are great looking boats IMO. We were particularly taken by the AR240's striking graphics and color scheme relative to the sedate Limited S, though it's tower was awesome!
Engine compartment. Yamaha is an engine company and it shows under the hatch. The engines "look" to be all business. Tidy and well laid out though a little busy with all the electronic panels back there. Lots of room to work. Easy filter access.
Interior. Excellent seating lay out and space utilization. Tons of storage, obviously on the 240 but very good on the 210 too.
Good ladders front and rear. Good **** pit and dash layout. Good under-dash design- no touchable/splashable or dangling wires ( they were in the storage compartment aft of the dash and behind a nice "drape") Removable table (Garelick?) looked of be of good quality. Gas tank, ski locker, and engine hatchs of solid fiberglass and latches worked well.

Negatives-
Fit and finish and quality control. This was the deal breaker for me. Examples-
Seats- all without hinges. You have to wiggle and wrestle them in and out of place- a PITA and reportedly rarely subject to flying away on the highway, though once in place they fit well. Vinyl is thin and stiff, though seat foam was good.
Head door- made of poly carbonate or some other plastic that was a silghtly different tone and texture as the surrounding fiberglass(?) On two models the door was warped and had variable tolerances. Seems that with computerized saws they could cut a door out of the tub, finish the edges and reinstall with hardware?
Walk-through/storage door thin, lightweight hinges and the "stop" that it fits into looked like and afterthought. Lame rubber latch.
Wind shield- this was a biggie for me. While all walk through windshields are inherently flexy, these were some of the worst I've seen, and with poor/angled tolerances when closed and bent-tabbed dash supports they looked to be something from Tractor Supply or Toys R Us. The bumpers for when open seemed haphazardly located and half ineffective. They should be embarrassed about this whole windshield spec.
Engine compartment/bilge area. Though I had a hard time taking my eyes off of the engines, especially those HO's, I couldn't help but notice the sloppy composite cuts where the exhaust exited to the waterbox and busy bilge floor shapes that looked to be difficult to clean and had many many places that pooled water, though it was gel coated (per the sales man, or was it a composite instead of glass??- looked too smooth to be the later)
Hull.- while this might might be a minor thing or just how things are done these days, the hull above the rub rail and into the interior (with the exception of the hatches) sounded as if it was made of a composite vs fiberglass ( or just very thin glass?) - not substantial sounding to the knuckle-knock test. Not may high stress areas I guess, but I just used to the feel of solid fiberglass both inside and out. Probably a weight as well as cost thing.

So in summation I've concluded that the Yamaha are not going to be for me. Conceptually they are great and they have a solid drive system, but the lack of attention to detail and assembly qc are something that this AR small boater can not deal with. Yes, though I didn't even test drive one, but that wouldn't change my opinion on the whole QC and perception of quality/lack there of. Unfortunately, after more than an hour sitting in and poking around in a few models, the Yamahas did seem like giant PWCs to me.

Now if in '14 Sea Ray brings their vast boat building experience and resources to the table with a relatively good/better QC, and if they have done their jet hull design homework, and the Webber engine/drive is on par, and if at a competitive price point, I believe that Yamaha will be losing a lot of market share very quickly.

Maybe I just need a Hinckley T29R :encouragement: As if LOL

Re: Yamaha jet boats- worthy?

The hulls on the Yamaha boats are made these days from a proprietary "nanocell" technology. It's not classic fiberglass. It's supposed to be more slippery, and have less drag.

We looked at them at the March boatshow, and a big negative for us was that the local fiberglass repair shop said that any hull damage would be virtually unrepairable. If there was a shop that specialized only in the nanocell tech, we would be looking at $$$$.

The engines are the same ones that Yamaha uses in their PWC - so getting engine work done should be easy.

There's a forum for them - yamahajetboaters.com - if you want to hear more from current owners....

Re: Yamaha jet boats- worthy?

The hull (both upper and lower sections) on Yamahas are fiberglass and are repairable just like any other fiberglass hull. On the forum referenced above, there have been posts by people who have had accidents and had repairs done. Perhaps QC has gone downhill since our 2011 was made in late 2010, but we've had no issues whatsoever with our (admittedly pretty new) SX210. Not sure what to make of the concerns noted about the windshield above...ours is rock solid. Perhaps the design or construction has changed in the past couple of years. There are a few detail items I'd like to see done differently - hinged seats would be nice, though we don't tend to store much under them that we need to get at regularly since there is such an abundance of storage space in the two floor lockers, the anchor locker and the port locker. I will also say that these are not the most heavily built boats, but we've not found ours to be the least bit fragile.

It will be interesting to see how the Sea Ray turns out. For us, our SX210 does everything we want a family boat to do right now, but competition is a good thing!

Re: Yamaha jet boats- worthy?

Don't just limit your jet boat review to the 2 new Sea Ray models. In a month or so, there will be Scarab, Chaparral and Glastron jet boats introduced, that use the Sea Doo Rotax power package. Four Winns will follow next year with similar offerings. The Scarab,Glastron and eventually Four Winns will all be made at the same plant in Cadillac, Mi. Expect a higher level of attention to detail from all of these brands than you found in the Yamaha's.
