seedoo speedster twin rotax

[hornet 13]

:hat:Further to my starting problems which I considered a new battery fixed. I took my speedster to the river and both engines started, however, as I pushed my lever to go forward, both engines cut out and would not start again. I checked my new plugs and they were sparking, the plugs also were wet with fuel!!! After approximately 2 hours of cranking the engines they both fired but would not idle on their own. I took the boat out of the water, I had half a tank of gas and took it to a gas station and topped the fuel tank tp full. I suspected my fuel had aged during the winter period and was the cause. I started the engines and after a few minutes they both started and idled. I spent a day and a half on the river and the boat ran fine. Now I am home, I tried to start the engines before putting it back in the garage, and again both engines would not start. I am down to nearly half a tank again. Should I syphon the old fuel out and put it in my van, then top it up or can I get away with just topping my boat tank up again and try to dilute the old fuel so that eventually I will have new fuel. If I have to drain the boat fuel tank, what is the easiest way to drain the old fuel out. Advice please on this problem. I believe I should have put a fuel stabiliser in when I winterised the boat!!! Thanks Hornet 13:hat:

i'd pull the carbs off, and clean/go thru them..and the selector valves. Make sure the xcellerator pumps are "squirt'n..

Sorry to take so long in posting my response, however, my boat is running really well at the moment. I drained down my fuel completely and put fuel injector cleaner in the tank, topped it up with fresh fuel and bigo, it goes like a dream. I can only think somehow my fuel had aged and that was the problem. I know when I winterize it this year. I will drain my fuel tank completely!!!
