New Tank Questions

[fillet1]

My boat is an 85 with the original tank. It seems that many of you with newer boats have had to replace their fuel tank.

Can anyone make me feel better and tell me that their older boat's original tank is still fine?

What signs can I look for NOW that will tell me whether the tank is ok or not? I have plenty of time now to replace it if necessary. I'd hate to put it in the slip for the season and then have to pull it to swap out the tank.

Thanks.
