210 SuperAir used for wakeboarding typically with 1800lbs of ballast. Compression check came back normal...all but one cylinder were within a couple of pounds of each other...one was out by 10 lbs. No code thrown, no temperature problems, engine was broken in properly and maintained with oil changes every 50 hours. PCM tore down the engine under warranty and said it had a problem with the rings. I don't know the exact nature of the problem but assume it was oil control since the compression check came back looking good. 330 hours on the engine when it was pulled...I started noticing oil consumption early on, but don't remember the exact hours. BTW, PCM has been spectacular in stepping up to the plate and addressing the oil consumption instead of telling me it's normal.

How did you determine it is the rings? did you perform a compresion test?
what boat. what prop on ir? how's it used? how many hours on the engine? what oil? any old code from temperature stored? |

Mine (2008 EX343) was burning 2 qts / 50 hr service interval. Turned out to be some bad rings. I thought my stick might have been inaccurate, but I tracked oil level by noting where it was when filled to spec (4.75 quarts I IIRC--turns out it was dead-on with the "full" mark), seeing where that put the oil on the stick, and then tracking how much oil it took to bring me back to that mark every 25 hours.
If performance is good / adequate, I don't know that there is any real benefit to rebuild based on bad rings...you can just put it off until you feel it's necessary and keep adding oil in the mean time. Maybe it'll get worse over time...maybe not. |

in the world of boats, most never even lift the lid, so if your a worry wart and the readings are low, do you justify pulling the motor down or simply just add oil?
thats pretty good oil your using, pricey, but try the Rotella and see what happens. the stick is there just to make sure there is oil in the engine, I really dont think the low or high mark will fail an engine, its when you pull the stick and there is nothing on it and the it alerts you that its time to put some oil in. I kept getting a 6 litre box truck at my shop, sure as *************** i would pull the stick and have to add between 3 to 4 qts every time in a 5 qt system, wonders of the world I guess, still running btw, i think your better off just doing what your doing |

Where is the oil level on the dipstick?
Dumb question but some people think the oil is supposed to be at the top of the dipstick tube. |

My Dads 2000 Lincoln would go thru almost 1 quart in 600 miles when approx 1-2 years old. Ford could never figure it out and finally said that was normal. Turned out to be the pcv valve. Maybe something was overlooked when yours was apart.

a compression test will help, do a comp test then squirt the cylinders with oil and try again, if it goes up then it might be getting past the rings, also with worn rings you will notice more than normal blow-by.
interestingly in my car i was burning a qt a month, I switched to Rotella and havtn burned any since???? |
