Volvo Penta 350 86 white smoke
Hey Guys, I have an 86 Penta 350 in my Bayliner and at start up there
is no smoke, but when it gets warmed up around 170, it starts putting out white smoke. My oil is clean and the engine runs pretty smooth however I am getting very little to no water out the exhaust and yes I have the outdrive with the prop off resting in a tank of water. No leaking water into the bilge. I just replaced the impeller and am now thinking of the water pump, but the smoke is making think there is another problem. Any help would be appreciated. Thanks |

Thanks Check the cooling system, is it a closed system? White smoke could mean antifreeze... -- Wafa free since 2009 Open system, no coolant. |

If no water is pumping, the temp may be too high and the oil is getting too thin. |

Thanks There are a lot of possibilities but it sounds like you are getting cooling water mixed in with the combustion process somewhe Blown head gasket Rusted risers or exhaust manifolds Cracked head or block Replacing risers and exhaust manifolds is routine maintenance - every 6 to 10 years for freshwater boats, half that for salt water. It it hasn't been done, that is probably your problem. |

Thanks My I/O impeller could not pull water from a "tank" ... could be you're getting very little cooling water and so the output is steam ... I'm surprised it's not overheating. I'd recommend the garden hose and muffs thingy ... then see if water's coming out the exhaust once up to temp and the thermostat opens. |

Ok here is were I am at. Took hose from raw water pump and un-hooked it from the thermostat housing. Started it up and am getting good water shooting out. Took out the thermostat. Filled the engine with water and flushed it a few times with a shop vac. Very rusty water. Put housing back on without thermostat and still no flow out the outdrive. Pulled one of the risers and they are super clean. I just replaced them 3 years ago, but have been working on this boat most of that time. I would say it has to be the water pump at this point. Yes? |

If the pump is working, why do you suspect it is the problem? Look for a blocked power steering cooler. Also some Volvo models have a sea strainer mounted on the engine. If yours has one you need to clean it out. Is it possible that you might have a kinked hose or maybe even have some hoses attached wrong? |
