Question Another 3GM30F Question

I, too, have a 3GM30F - a 1992 that was rebuilt in 2005. I bought the boat this summer and there was zero hours on the engine since rebuild. She starts every time and runs well but I did not realize you shouldn't run the engine at low RPMs.. most of the time I am in no rush to get off the water (as you can imagine) so I will hand the tiller to a friend, and put the rpms around 1500 while I go about getting sails down and covers on.. I kind of enjoy a nice slow putter..

However, it sounds like I should not do this? It isn't used too much - maybe an hour or two a week, tops. I know that when I get up towards the 3k RPM range I get pronounced smoking (white) out the exhaust but I have never left it that high long enough to see if it clears up when the engine warms up.. likely this is just moisture/steam, or suggestion of more troubling problems?

Thanks in advance, sorry to hijack the thread.
