I had an MDM7649 on my '52 170B/edo 2000s for about 50 hours, quite a bit of clenching on the smaller lakes. I've had an 80x40 for over 10 years and would never go back. It drops the cruise to 93-95 mph, but takes full advantage of the 145 hp on take-off. I've let Sedan owners try it on their seapla...

Maxwell Aircraft Service, in Crystal, MN, converted a McCauley DM7652, off of a Stinson, to an MDM7649 seaplane prop for my 170B. It came with the Stinson spinner, so was installed with the prop. So many questioned the spinner that we replaced it with one from Wag-Aero. It sure looked good. The only...

My wife, at Crate & Barrel, saw a framed, old b&w picture featuring a woman standing in front of a 170 on floats, possibly in a New York harbor. She's upset that she didn't buy it and hoped that one of you knows of the photographer or its title? I'm assuming I'll be unwrapping it for Christm...

how about finlets, like the 195 on floats?

I'll have to loose weight :lol: with a 585 useful payload.....2 persons and gas must not leave much for cargo. Martin I found a 1977 C172 XP on Wipaire 2350 amphibians for sale on-line. It boasts a 552 lb useful load and 72 gallons useable fuel, leaving 120 lbs for the pilot with tanks full. Dieting...

That does happen to be my plane online, I found it when I searched my N#, I'm still using Ectochrome.
There was a Norseman sitting at Surfside Seaplane Base years ago, I'd sit in it and make engine noises.
600 hp on 7170s, painted cub yellow, that would be the ultimate floatplane.

The STOL kit certainly helps, however, it was the 80x40 changeover from the MDM7649 seaplane prop that cured the pucker issues.
Before the new prop I was greatly limited to which lakes I could utilize. It does drop the cruise to ~95 mph @ 2400 rpm.

I've been flying a 1952 C170B 145hp/Edo 2000s for 15 years. Useful load is 585 Lbs, so it's a two-seater on floats. The McCauley 80x40 prop makes it a fun, safe and useful floatplane. Check out - www.airport-data.com/aircraft/photo/198450L.html the only thing as pretty on floats, is a Cessna 195. I ...

Is there an approval to install Bird Dog seaplane fins on a C170B?

How much do the Aerostops cost?

I bought my 1952 170B, N1676D, on Edo 2000s with the 2-speed prop in 1996. Flat pitch allowed me to jump up on the step, then once at altitude, adjusted power to 1500 rpm and shifted to cruise. It was a selling point on floats, but only worked for 3 hours. It had a rebuild sticker from Anderson Prop...

No factory records?

-Bill

Is there a good estimate of how many 170As and/or 170Bs have float kits, factory or modified?

Bill

I currently run an 80x40 with the Kenmore STC, it's the best you can do with
a 145hp. Prior to this prop I used a 76x49. It had a great cruise speed, but tested the nerves getting out of smaller lakes. The 76x47 should be ok, and it'll buy you some time to find an 80".

I've got a '52 170B and a Maule M5/235. If you need a 145hp airplane, get a 170 or a Sedan. Maules are useful when overpowered, then you can overlook the ugly tail, visibility and egress issues. Nothing I've flown has the visibility of a 170. Not many planes provide forward visibility when the tailw...
