As succinctly as I can:
is a 3cyl Perkins Perama
, either 24 or 27 hp depending on what paperwork you read. The hours are unknown but not too many judging from the condition and the engine
is a little under propped. Our normal motoring is at 2000 rpm
Recently we had to motor
home for three and a half hours due to a lack of wind
. There was a short steep sea right on the nose and the boat was pitching quite a bit. H28s are notorious for hobbyhorsing. The last half hour to our mooring
was in flat estuarine waters. The estuary is very shallow and it was a hot day so I would guess that the estuary waters were 2 or 3 degrees warmer than the sea outside. On the mooring
with the engine at idle, it began to produce an amount of light grey smoke. Apart from the smoke, all engine operating parameters were normal. I shut down and went home to sulk. Next morning we motored the boat for half an hour or so, and have run the engine on the mooring a few times subsequently with not the slightest trace of smoke from the exhaust
- everything is as it should be.
Engines make me nervous and I am wondering what was going on here. My wife's take on this is that the engine thought it would take up smoking. Tried it, didn't like it, gave it up.
I don't think its that simple.
