Hey all,
Boat was running fine for 2 years now. Ran into this issue on the lake today.
Went out, fired up no problem, went full throttle and was cruising. After 5 minutes the motor sounded like it was dropping a cylinder. I throttled down and was able to maintain about half speed just fine. I nursed it back in to safety.
On the way back in, I noticed middle cylinder did not have spark. (pulled wire quickly to check to see if any rpm dropped on all cylinders). The cylinder would get spark after I let the motor sit for a little bit. I had new coils and spark plugs sitting around so changed those.
I launched the next morning and ZOOM full speed, thought i fixed the problem. 5 minutes later, same thing. Felt like it dropped a cylinder, it slowly idled itself down and would not be able to have power past a slow troll. I checked spark again and spark was there on all 3 cylinders. Possible intermittent spark problem?
I ran the boat and squeezed the ball throughout, did not fix the problem.
I ran the boat with the air cover off, i did notice A LARGE amount of fuel pumping out of the top of the top carburetor. Looks like it was from the idle orifice?
I need to run compression and spark test when I have the time this week. Anything based on the above to look for/start with? Possible carb rebuild? Powerpack? Stator?
Any and all help is greatly appreciated.
