Default MS80-430 FLOAT KIT

It's time for the CI on one of my Rotax 912s. I have read every post in this thread and I want to thank everyone for their fantastic contributions. It appears that MS did what Jim (Piper J-3) suggested --- removed material from the top of the float to reduce the weight. I sincerely hope this long sad saga is over! I ordered two pair of MS80-430's today

I have two Rotax 912 ELSA powered airplanes. One with 277 hrs (2006) and one with 102 hrs (2005). Both were run exclusively on 91 Non-Oxygenated Mogas in Minnesota. The floats still meet specs, BUT as pointed out in this forum, one month after weighing them, they may sink.

As of October 2019, I have switched to 94UL Avgas (Swift Fuel) which is identical to 100LL without the lead. Unfortunately this fuel is not widely available, but hopefully that will change.

Thanks again.
Rob

BTW Jim, I learned to fly in a 1946 J3 C65 - N6848H. Your J-3 (N6841H) and mine must have been on the mfg floor at the same time in 1946

As I continue my work on getting my new to me plane up to date, I ran across the 14-10-14 REVISION 1 Service Bulletin that hasn't been addressed.

According to my logbooks, looks like the prior owner installed floats three different times. The last floats were 861-182 floats in mid-2015.. Guess I'll soon be weighing the floats to see if I can join the Sinker Club too... Based on everyone else, I guess I can probably expect to be replacing floats.

Has anyone ever had a Rotax 861189 float go bad yet? I saw the one person mention it, but never reported back with further information, so I'm not sure.. Anyone else?

How about the Marvel-Schebler/McFarlane floats? Any of those gone bad or started getting heavier yet?

2012 RV, 265 hrs, almost all Mogas, last 95 hours straight Mogas with some Ethanol, and any other clean air additives here in Los Angeles /South Air Coast Basin fuel requirements.

Still on original floats, probably a 2011 motor.

Beginning to think it's not luck of the draw, it's what junk the refineries near you are dumping into the fuel as waste, to burn it and not have to put it somewhere else, and pay to dispose of it.

Think of your engine and fuel system as an incinerator for some undesirable waste the refiners add to your fuel, that is a byproduct of refineries.
