I recently boat the referenced boat from a private party. The boat
was in mint condition with only 44 hours on it. Test drove it and
seemed to work fine. Now that I've driven it more i'm a little
concerned about some engine noise / minor vibrations. It seems when
I'm on plain, the engine noise / vibration is normal if the trim is up
(even by one notch). But if I trim the motor all the way down (while
on plain), the engine noise increases and so does the vibration. The
vibration feels like it is coming from the engine area or towards the
back of the boat. I'm not sure if I'm overreacting or if this is
normal. I mentioned this concern to my wife and she didn't even
notice. If anyone has any thoughts I would appreciate it. thanks.

Putting it all the way on trim is putting undue forces on the mechanics
of the hull/engine combo so it's gonna' strain a bit. Don't over think
it. Remember the story about the guy that told the doctor that every-
time he took a drink of tea with the spoon in the cup, his eye hurt. The
doc said, "take the spoon out".. In-other words. Don't run it all the
way on trim if that's not how the boat is weighted...
