Thanks for the response guys!
It was an exiting day to say the least.
At this time of the year there is not a single boat left on the lake so it took some time before being rescued. The firemen came and pulled the plane to a local marina where I cut the hose fixed it and took off again. I knew that taking off again without checking the engine was risky but I did not want to leave the plane along the lake for the winter. I made it ok to the airport, about 10 minutes. The engine turned by hand and had all the exhaust pulses and it did produced full power as usual. It was a good takeoff, my first on the water.
The oil hose broke at the fitting, (it kind of sheared and pulled out of the fitting) a mechanic said the outer fitting ferrule might have been pressed too much and had damaged the hose itself. In any case this is not the type of hose that should be used on an aircraft. I had my douts about this type of hose. Unfortunately, I was right.
Now, there is another thing about this hose. It is not very far from the exhaust stack (I will measure the distance). The other hose that connect there is coverd with a fire sleeve, plus wrapped in foil, because it is closer to the exhaust stack. I will have to check that more closely. Did not think of this heat damage possibility before now.
Yes the oil pressure warning LED will be there on the instrument panel the next time the engine start.
I have Tracy's EM2 and the pressure display flashes when it is low but there is nothing like a flashing RED light to attract my attention.
Quite a few lessons learned here and probably more are coming up!
Back to the hangar!

Great flying, Rino!! Dead stick landings (having made three in my 10 years) always get my heart rate up a notch not to mention disappearing seat cushions. Fortunately, the rotary has a lot of bearing area and can survive longer without adequate oil pressure than most engines – but, as Lynn said, tear it down, rebuild it and let us know what you find.
