sig senior engine
 

I have a sig senior on floats set up with 3 channel that i got used I put a thunder tiger 46 off land but didn't know if i should put a 60 + engine on it or for the water i have a 65 os la ,and a 61 magnum

I've gpt an OS .90 four stroke in my Kadet senior and it's not too much. Flies good. The bigger engine you've got might be ok.

Good luck

Here's a couple of pics at the pond.

I have seen Seniors fly from water with .40s all the way up to .91Four-strokes. A TT46 is a good motor and you should be able to fly just fine with it.
It is a myth that floatplanes need gobs more power. Full-size piper cubs carried floats around with only 65 hp. This one has a .45 and it would hover.

I don't remeber what the white one with the red stripes had for power.

If yours seems to be underpowered, you probably have those awful, heavy, oversize, built-up plywood floats. Get some nice light foam-core floats and go have fun.

Of the choice of your three engines The no brainer choice for me would be the .65 LA. It is an ideal engine Size/user friendliness in a two stroke for a Senior on wheels or water. I have flown many Seniors on and off the water my own and for others and that LA65 is a great engine for a senior.

I have a 70 4-stroke on mine, and in my opinion, the perfect match. I'm using my 42" slim foam core floats without a water rudder.

Have had both a 4 stroke .56 and a 4 stroke .72 in mine. To me the .56 is a little more realistic power. The .72 was effortless.
