Hi, (2003 75hp Mercury) After how many hours would my new motor be broken in at? I put 5 hours on it this past Friday. Also should I change the spark plugs after break in? Thanks for any info.

The Owners Manual will tell ya ;) <br />20 hrs for my Hondas 45/50. <br />New plugs (the old ones for spare) and new oil in the l/u .

Thanks for the reply, the owners manual says 100 hours, they don't mention anything about changing after break in though?? This sounds high to me. My plugs are surface gap, does this give them longer life over the gap type?
