I have a '92 Yamaha 200 TXRQ that will start and idle fine, even rev to high rpm's in neutral with no problems but when I put it in gear and try to give it gas it bogs down and will stall out. I can immediately pull the throttle back in time to keep it running but if not it will just choke and die. The last time we went out I idled away from the ramp for a few minutes and when I went to take off it wouldn't go, just died. I putted around for an hour trying to get it to run faster and finally did manage about 10 minutes at 3500 rpm. As I approached the marina and throttled down seemed like my issue was over. But once I tried to inch the throttle up again I was back to the stalling behavior and never could get it to run faster than idle again. By the way, it ran and did fine in the driveway before we left, seems that under load is when it has this problem.
Here's some background that might help. My boat sits alot, especially during winter, and has old gas in it treated with STABIL. Last fall I used the newer blue STABIL which supposedly is better for E10. The engine has always run like a top and even though it is a '92 it only has 500 hours on it. 2 years ago I put in a new aluminum 70 gal. fuel tank and new fuel lines. Last fall before storing, I filled the tank up to help keep condensation from forming and depositing water in the fuel. Yesterday I put on a new fuel water seperator (the old one showed no signs of water) checked the plugs (which look fine) and checked the fuel filter which was spotless.
If I recall correctly while we were out having this trouble the primer bulb was not collapsed and still tight which leads me to believe I have issues in the engine and not a fuel delivery problem from the tank. Plus when I installed the seperator it filled quickly by pumping the primer bulb, same with the filter bowl.
Any ideas what could be the problem? Any suggestions as to what I need to look for or can check next? Does this sound like a carb problem?
Thanks in advance for any ideas, suggestions or information you can provide.
