Yamaha G14 JN5 Seized engine

Fentron · 08-14-2019, 08:00 AM

Hello,
I just finished my first summer as the Director of Maintenance at a small christian camp. We have a Yamaha golf cart used for transportation around our 100 plus acre facility. With being busy with summer camp, I never thought to check the oil. The engine is seized up. I pulled it out and began taking it apart. I am not that familiar with engine repair and don't really have the time to dedicate to rebuilding it. Are there people out there with used engines that are looking to sell them for a reasonable price? The engine is the JN5 300cc. From what I can tell based on my research the cart is a Yamaha G14. I am learning as I go and grateful for any help.

You are correct about the model. And the G14 engine is specific to only the G14 (and made only in 1995 & 96). The more common G2-G9 motor could be made to work, if you used the flywheel & ignition pickup from the G14 motor, but it is a little smaller (285cc vs 301cc).

I know this is a long shot but do you happen to still have that G14 motor? After I posted on here I got busy with other projects and forgot about it.
