Your post and mentioned articles forced me to get dipper in propeller theory it took awhile and now picture become much more clear.
Many thanks for your kind assistance.
PS I found an example how to connect dry turbo to wet exhaust manifold

Dear Tony, many thanks for your reply.
Understood that idea of swapping to marine pistons is complete nonsense.
Regarding engine cooling and wet exhaust everything clear, thanks to your very informative and detailed website, my boat will have HX cooling and wet exhaust, importance of the high of dry part understood as well.
Just one more dark area, prop calculation, if the boat requires 170HP to sail with max waterline speed, why to use engine rated power for prop calculation. This extra power will considerably increase fuel consumption with no effect on speed. More over for cruise speed will be necessary only 120HP, that means most of the time propeller will run in inefficient range, or I’m wrong? as with marine pistons 🙂
