2 Stroke outboard white smoke

White smoke from the exhaust of any internal combustion engine is cause for concern. In an outboard , though, it may mean something other than a tow to shore and an expensive repair. The dreadful white smoke ! Sometimes it is ba but there are certain instances where you can see white smoke , due to an overheat issue.

Dealing with an outboard engine that is using seawater to cool it down, if there is a clog somewhere in the cooling system, the engine can heat up and turn the cooling water into vapor. I have a 30hp -cycle Evinrude outboard. Try cutting your mix just a bit and see what the reult is. I used alot of OMC carbon guard and Seafoam at the same time and the gas in the tank is over year old.

This helped cut the smoking down. See the in the video. If it were a 4-stroke , then bad rings would make it smoke but, a 2-stroke would just loose hp. I adjusted the carb on both the HL screws to 1. It’ll smoke the most on start up and when you first start out. Time for a oil change if it does.

I took my bike into a shop to have them replace the oil seals between the water pump and crankcase on the right side and now when I start it a bunch of white smoke is coming out. It was not this white before I took it in. I removed the spark plug and it did have some oil on it. When the - stroke motor is started dead col it tends to produce MORE blue smoke.

If combustion was complete, there would be no hydrocarbon emissions. My question is could this be just normal, the white smoke comes a few minutes after startup and continues at any rpm except a few seconds after i bring her down. If after a good fang at high revs it is not smoking heavily (expect some smoke with any two stroke - no smoke at all is actually not good with any older design!) and takes some minutes at idle or slow revs to start smoking again then it is probably a build up of residual fuel in the crankcase caused by incomplete. So it seems as though when I take the boat up to around 3k-4k and cruise for. Mercury outboard 60HP.

Johnson seahorse, not sure on exact year but pretty sure its early 80s, stroke. It might be stating the obvious, but your scooter like most modern stroke bike or scooter engines uses an oil injection system, what that means is that unlike old strokes you do not put oil in the petrol, rather you add oil to a separate oil tank and the engine takes what it needs from that oil tank. One of the major engine failures of an outboard motor concerns the temperature and operation of the piston. Responsible for compressing the air-fuel mixture, then forcing it from the exhaust, the piston can overheat and suffer catastrophic damage from a number of reasons.

If a boat owner knows what can cause a burnt. For this reason, outboard engines wear out faster, absorb more heat over a longer period and work under a constant load. Outboard engine cylinders also take a beating when it comes to ingesting water from their environment or cracking as a result of improper winterizing procedure. Some outboard cylinders simply crack from heat and stress.

When I first turned it over, I had. Any ordinary two stroke lube oil will do for lube injection system. Normally stroke ouboard marine engine does not have as much coke as motorbike engine, but still cleaning the head and piston crown will give a better performance compared to not. It is missing, especially in idle.

It also seems to sneeze when the rpms drop and smoke comes out from just under the cowling.
