Hi Im looking at a 1988 340 Express with 454 Mercruisers with 1300 hours on them. I am a little concerned with the hours. What is average life expectancy of these engines provided they were properly maintained? Ive read well over 2000 and ive also read that they will need valve jobs right around now. Would a compression check be good enough to check current condition? I have to find out when manifolds and risers were done last. Havent seen it in person yet but rest of boat looks very clean and neat in the pics. Guy is asking $9k Thoughts?
