Mercury 100hp inline 6, My engine feels sluggish

[FSAE]

I've got a 1971 Mercury 1000, inline 6 Thunderbolt ingintion. It doesn't feel like all the<br />ponies are working. It has not had a tune-up in more years than I came remember. What<br />are the usually suspects that could be robbing my power?

welcome John,<br />I have a '70 inline 6 1150 that had this prob.<br />turned out to be "fuel starvation" under load.<br />I reccomend doing a search under that problem<br />on this site first. could be carbs, tank/vents,<br />intake lines, pumps etc. <br />good luck <br />M.Y.

check your spark plug wires and coils and make sure you are getting spark to all cylinders...then go on from there

If no tune op for many years Start with new plugs.<br /> Check compression.Get a manual.
