Looking at a few boats in the 1995-2000 era with gt-40 engine. Beside the digital gauge issue is there anything else I should be looking for that’s a common issue with these boats? Also, what are reasonable prices? Seems like people are asking a lot $15k+ for these older boats. Some of which are in excellent shape with low hours but low hours means it sat alot. I owned a Mastercraft for several years so I’m not new to boats. Thank you for any input.
