I was riding in the back while my wife was driving. I noticed that when she had the boat in gear but was just idling there was a mild tap-tap-tap sound. It was either coming from the floor behind the engine compartment or inside the back of the engine compartment; probably both. However, when she gave the engine some gas to pull a skier, the knocking either stopped or was drowned out by the engine. We had too many people and too much equipment in the boat for me to do a thorough search on the water.
Is this noise normal? dangerous? simple to fix? ------------- There are motorcycles; and there are Harley Davidsons. There are tractors; and there are John Deeres. There are ski boats; and there are Ski Nautiques! |

from your description it could be many things, you need to do a little more investigation. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=2095" rel="nofollow - 1980 Ski Nautique Commander 351W |

| Read about damper plates. Is a common thing specially if your boat alignment is off. Tons of stuff on that and alignment |

what's your rpms at iddle speed? sometimes if they're too low bumping them up will solve the clanking sound. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=2095" rel="nofollow - 1980 Ski Nautique Commander 351W |

I know it idles at 800 when not in gear. I'm not sure what rpm when in gear. We will probably go Saturday if the weather allows. I will do more investigation, but what exactly should I look for?

you want to see how much they lower when you put the boat in gear, feel if it makes the noise and then give it a little gas until it stops clanking. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=2095" rel="nofollow - 1980 Ski Nautique Commander 351W |
