Leaving it to next haulout doesn't sound too bad to me but some engine
manufacturers wont honour the warranty if you are over-propped. Good idea to be a couple of hundred rpm
below max as you said you would do probably. If the coolant
temp & oil
pressure & temp is ok you can't be overloading it too badly.
The problem for us being overpropped is we cant get to max hp in the rev range so we get drastically slowed in a headwind & sea but I'm guessing you still have adequate power with that size engine.
I'm not at the boat right now, but the engine hours are not that high at all. Sadly we don't use the boat as much as we would like to.. waiting for someone to retire first! But I do recall
the technician who serviced the injectors mentioning that he was surprised by the poor state of the injectors with the low engine hours.
My guess is that because the PO had the boat out in a rental pool for a year before we purchased it, there had been some poor fuel
in the tank at some point.
I had the fuel "polished" prior to the injector service
and the fuel and tank were in very good shape in his opinion.... so I have been "good" to the engine from a perspective of fuel. But I was just not running the engine hard enough.
