Hi, Thanks for the help in advance. I'm a new to owning such a big boat and I'll have many questions. I bought a 1995 729zp with a new 5.7 litre that was installed in 2007, but lthen only run for ten hours to seat the rings. Since then it has sat with 3/4 of a tank of gas that I think I should remove. I've tried to syphon it out but the hose stopped without reaching the gas. When the last owner stored it, he winterized it and put STABIL in the gas but I hate to run 18 month old gas in a new engine. Is there any way to get it out? Or will mixing it with new gas and running it through the engine hurt it? Will any additive help? Thanks.
