| My friend is thinking of selling his 1990 Yamaha sit down ski. It's sat outside (So.Cal, so the weather isn't horrible) for the last 12 years not touched. I was thinking of slapping a battery in and seeing if it starts. Is this a bad idea? Do I need to do anything else before trying? My friendad thinks it will just need a battery, change the plug, and a tune up. We have not discussed a price yet. |

It may very well be worth zero or even negative. Go price running jet skis on Craigslist from that time period, they are cheap.
If it needs a top end probably not worth taking for free. If it has a trailer, I would not trust tires that old no matter how good the tread is. |

It's going to need all the fluids (oil and gas) removed, fuel system cleaned out, carbs rebuilt and all the fuel/oil lines and water hoses changed out at a minimum. So. Cal is similar to Arizona and in my 13 years as a boat mechanic I've yet to see a "derelict" boat/ski that didn't need all of this done. You may get it to run by just draining/adding new fluids, but it will probably run lean (due to dirty carbs) and burn a hole in a piston under load. Did it sit with any water in the hull? Was it used in salt water before it sat? Corrosion is a big issue too so be aware of that. Chances are good the "bellows" where the shift and steering cable pass through the transom are rotted and need replaced too. |

I may offer him $100 just so I can fuck with it. |

You haven't specified the exact model, but Yamaha's best ski from 1990 is only worth $1,000 now if it's in perfect running condition. |
