Ok, last weekend I was out cruising on the lake. I wasn't doing anything stupid. Just cruising at 35 mph when out of no where my ski just bogged down and wouldn't go above 10 mph at full throttle. I drove it to shore and got it towed back. Its here in my garage and when you start it, there is smoke coming from the front of the engine area under the seat. Replaced ignition coil, cleaned carbs, checked fuses. We put a timing light on the wires and both seem to be fine. both cylinders are hot after running it for a few seconds. Its kinda frustrating. The ski is a well kept ski with 125 hrs. On the trailer it idles at about 1000-1250. it revs on the trailer. When its in the water it takes a while to rev up. I dunno. Any suggestions or any way to test for faults would be greatly appreciated. I'm heading to the lake this weekend with or without it. Lol
