Thanks for all the good advice, this forum is great.
It will be very hard for us to do anything under water
since we are not diving
ourselves and there are no services available for recreational boats, which means we can ask industry services but it will likely be very expensive, more than it's worth for us. I will ask them anyway and see what they say. Otherwise I will wait until on the hard
in July and see what I can do.
There is no water
in the diesel
filters or in the oil
, which speaks for OK diesel
quality and tight gaskets. The engine
is old, so the smoke could be something else, I agree, but the fact that the smoke intensity increases a lot after a certain power input makes me believe that it has something to do with the prop.
Being able to try out several prop sizes and pitches would be great, but not possible right now. The previous owner said he tried calculators and three different props and finally got stuck with the one that's on now and agrees that it's too big but the best choice they had back then.
