I purchased a boat with this motor and the motor is throwing off a lot of smoke (very bad when you are downwind), but has good oil pressure and starts and runs well and doesn't consume much oil (suprizing). I suspect worn rings or a cracked ring.
Is there are a way to inspect the rings without dismantling the motor?
Also is a ring change a job that can be accomplished by a weekend mechanic? Any special tools required? |

You may be right about the rings, but I have a feeling they are okay. I would look for a rich mixture problem, or worn valve stem seals.
You could replace the rings without any special tools; but lots of patience. Valve stem seals would require a valve spring compressor of some type. |

If the motor burns oil and smokes when first started or left not running for some time it would be valve stem seals.
If the problem is smoke when under way i would suspect a ring problem.
Yes a weekend mech could strip and rebuild with a gen manual |
