Motor work on the 'muffs'

[chris in va]

Ever since I bought my 94 Caravelle 5.0, it's had tons of work done while on the water muffs. When I give it some gas in neutral there is this loud rattle from the outdrive around 1500-2800, then it just sounds like a normal V8 revving. Is this harmful for some reason?<br /><br />I'm new at this, so trying not to do anything that will hurt the boat.

It is probably the u joints.Trim down as far as you can and do the same rev and listen.If it were a clicking sound,that would be the drive unit.If you can hear it inside the boat it is the exhaust shudders.None of these are unusual. CC

Even in neutral? It sounds like...*ahem*...<br /><br />mmmmmmmAAAAAAAAAAArrrrrrrrrrmmmmmm, as you progress through the rpm range. Pretty darn loud. It doesn't do this when in the water, best I can tell.

That sounds like the u joint.If trimming all the way down,the sound should go away. CC

Nah, the trim is all the way down. I don't have it in any gear, just neutral.
