Less smoke

[zach103]

I have an 88 SPL started it up today and theres a lot more smoke(exhaust) than i really want.. im sure the water will get rid of some of it .. i also bought a new oil. the Johnson & Evinrude XD50 it says it should cut back on it. but what else can i do to reduce it??

sorry if i used the wrong lingo or anything else newbie to engines trying to learn i searched but couldn't find anything unless i searched the wrong thing

Re: Less smoke

on an 88spl you do not need ezpensive oil, any TC-W3 oil is fine. synthetic TC-W3 will cut some smoke, they also smoke more on muffs.

doing a decarb, will get excess carbon build up out of the engine, and exhaust housing.

Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray bottle. start the engine, and let it come up to temperature. then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone.then take for a wide open spin. then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.
