We are in the search for our first Searey. Since we are not yet owners, we cannot access STS so thought I would ask here... is there a big difference between the 914 and 912? I have been told by most to get the 914 but have had a couple say to get the 912. I have been told the 912 is better as it is a true 100hp engine while the 914 is a turbocharged 80 hp engine and will thus require overhaul sooner and more maintenance in the interim. Living in Florida, would the 914 with turbo be better in the heat? Any advice is appreciated.

Daniel, site rules discourage technical discussions here--but maybe we can say this much: Both engines work just fine in a Searey, and both have a recommended TBO (time between overhauls) of 2000 hours, so there's essentially no difference in their durability. All of the Rotax four-stroke engines can run at up to 5800 rpm (the prop is geared down) for 5 minutes. Maximum continuous power is at 5500 rpm. | Engine | 5800 rpm | 5500 rpm | | 914 | 115 hp | 100 hp | | 912S | 100 hp | 95 hp | | 912 | 81 hp | 79 hp | The 914 is turbocharged and can produce sea level pressure up to 9500 feet. The other engines are normally aspirated. (There are two new Rotax engines, but no used ones on the market yet.) On a Searey, there's not much performance difference between the 912S and the 914. The 914 may climb somewhat better, and the takeoff distance may be a few feet shorter. But cruising speed is essentially the same because power required increases on the square of the speed, so a small increase in speed needs a lot more power. What's more important, I think, is which hull configuration the Searey has. All Searey kits produced since about 2002 have had the "C" hull. The C hull is notable for its double V at the step--downward and backward. The earlier hulls, A and B, have a straight step and require somewhat more finesse on the water.

What Don said. Shape of the plane is more important than 100 vs 115.
The turbo is more maintenance but both are very reliable if treated with reasonable care.

Having owned both engines, in a Searey, three different years, what Don said is pretty accurate.
The 912 S is a lot cheaper, does a great job. The 914 does help a little, if you fly with heavy passengers alot.
Or short field take offs.

Daniel, No offense to those whom have answered already, but the LSX is a heavier aircraft then the earlier Searey's. In my opinion the newer plane (especially with all the gadgets) needs the 914. I've flown both, and I can certainly tell the difference.

As you note, Jim, the heavier airplanes definitely benefit from more power. A variation to the “new is heavier†rule would be the
sLSA Adventure model Searey. It is 40+ pounds lighter than the Elite model and is a joy to fly with the 912S. Flying to the
Bahamas with two Elites it routinely burned significantly less fuel at the same airspeed (but higher RPM). Of all the factory models
I’ve flown it is my favorite. Unless you need to fly in the mountains a light SeaRey will do just fine with a912S.

Dan, how did they make the Adventure model lighter? Are they selling a secret ingredient at the store?
CF hull would be a big factor, anything else you can talk about?

Good questions, Steve, but the answers are best left to one of the company’s sales staff and/or the technical site, secret ingredients
being, well, secret.

Gotcha. Will give them a call and see if they can share some of the herbs and spices.

I've got the 914 and like its performance, although I fly with folks with 912s all the time without any
problem. I do envy the improved fuel efficiency on the 912/912is, though. I burn gas faster.

Okay, to expand on this subject (you can message me if that would be better)... recommendations for an instructor and prebuy? The plane I am looking at is at Apopka.

Angel Rivera / Daniel Meyers are both at Apopka. Angel does work on my Searey about every year. I bought mine through Daniel,
who did my transition training. Angel/Daniel did the pre-buy. Both are great guys.

Daniel, From your research you did find that Seareys were at one time powered by the 80HP?
My 100HP is plenty for me, since my usage, as I suspect is fairly typical, is not high altitude, not fast, but Florida down low and slow.
If you're looking for a cross country airplane, look elsewhere. For my money, empty weight is more important than 115 vs 100 in a
SeaRey.

They were once powered by the Rotax 582 (64hp I believe)

Hopefully, the 914 will help get my fat arse up in this Florida heat!! We closed on her today. Let me know when you can get me up, Dan. Looking forward to it!!
