Mass quantities of good discussion. But I have not seen mention of the standard starting test, iusually seen here:
1) Verify engines are at ambient temperature (have not been started, before you arrive)
2) If engines are reasonable, should start in 3-8 seconds; may start immediately
3) The standard quoted here has been a good engine will stop smoking in "15 seconds"
I find this true on my 1972 43' DCFB with DD 6-71N's (Naturals).
One engine was in-framed, about 100 hours before I bought the boat. The other engine is original state. Both have about 2,200 hours.
1) The in-framed passes the 15 seconds, then no smoke test
2) The original is grumpy to start, then smokes for about a minute; not massively, but not clear. In fairness, I block heat the orig state engine and avoid the smoking grief.
P.s., to me is mandatory that when started, the oil pressure gauge should rise to about 55-60#'s, then drop back to 50#'s. Both my engines do that. This is due to a pop-off valve on oil pressure that releases at 50#'s. When out running at cruise, should hold a steady 50#'s and idle hot at 15-20#s. I am surprised that boats being test/sea trialed, e.g. on Youtube, do not run at 50#'s, sometime much less.
