I have a new 2012 mercury optimax 115 on my new boat and am having some issues. This is only my 3rd outting in the boat. The boat sat in the garage for about a month then today I took it to the gas station and topped it off. It took 7 gallons. I also added some mercury quick clean. Then I topped off my injector oil and launched the boat. I took two passes around the lake, maybe 15 mins total and it ran like a champ! Got right up on plane and ripped along, cruising at 4500 rmps. Then I pulled up to my dock and farted around with the girlfriend for a while before we went out on the boat. I trimmed the motor up and used the trolling motor for an hour or so. Then when I started the optimax it didn't sound as smooth as it normally does. It sounded choked, like the old days with choke levers. It struggled to get going and topped out at about 2100 rmps at full throttle, not even able to get on plane. I'm not getting any alarms but called my mercury guy and he said I might have topped it off with bad gas and it just took that long to get to the motor or i over filled the oil resivoir and its over oiling itself. He said to add another ounce of quick clean and to run it as long as no alarms were going off, which there are not. So I did with not much luck. Then I docked for a while and got some lunch. When I went back out I started it and it sounded smooth, I pulled out of the dock and shot off like lightning, got on plane and hit 4600 rpms with ease. Then half way across the lake it started to bog and went right back to topping out at 2100 at wide open or so where it spent the rest of the day when I tried to get her going.
Anybody ever experience anything like this? Bad gas? Any solutions or suggestions? Add Isopropyl? Sea foam? Im at 3/4 tank now, drain it? If so, that's a lot of gas! Oh and one other thing, how hard should the fuel squeeze ball be? Mine doesn't stay rock hard - yup, I just said that.
Worth mentioning the BPS I bought my Nitro from is 8 hours away from where m boat stays.
Thanks in advance guys! Oh and we did get some nice bass today too.
