Yesterday morning we headed to the lake for some fishing.
Looks beautiful, right?
But NO JOY!!
After I got the Merc started, it kept wanting to die unless I was at high idle. I figured it was still cold, so pressed on. Got everybody in the boat and idled out of the no wake zone, hit the gas and the engine started to rev up, then bogged down! WTH?!? The motor ran perfectly on our splash 5 weeks ago. :mad-new: :grumpy:
I'd been sure to open the vent on the gas tank before launching, but checked it anyway. It was closed again (the boy.) So, I opened the vent, idled some more and hit the throttle again. Same result! Started to rev up, then bogged down.
Disappointing to say the least. At that point I decided to check out how the Minn Kota 45 Edge trolling motor (45 lbs thrust) would pull the little KF around. Disappointment again! It seemed to actually be slower than the 28 lb thrust motor that it replaced. The brand new deep cycle battery was fully charged.
:blue: I ordered a new prop for it last night, in case the one that's on there was incorrect for the motor. (Purchased the TM from craigslist.)
While idling back to the dock, I surmised that the fuel in the tank must have gone bad. That's the ONLY thing that changed concerning the engine in the last 5 weeks.
I thought about it some more and talked with my wife and the boy about it while I was driving us home. That morning we'd topped off the tank. The leftover fuel was about 2 gallons so we added 4 gallons, mixing in the oil too. I realized that the old fuel wasn't just "a couple months old" but in fact was now about 7-8 months old. :facepalm:
So, I'm thinking that running the old fuel on "splash" day through the newly rebuilt carbs must have gummed up the works. Adding the fresh fuel yesterday morning was too little, too late.
On the way home we stopped and bought a new can of Seafoam and after I dispose of the 6 gallons in the tank, I'll buy fresh gas and see if running some Seafoam through the engine at idle will clean things up again. Else, I'll have to pull the carbs and clean them again. Ugh.
The good news... the guide-ons worked perfectly. The Bimini top was very nice too.
