Q & A

prop distance

is there any proper distance between stern tube and prop ie min or max

WW says:

A sensible minimum distance would be one inch between the propellor boss and the stern gland- two fingers width is a good starting rough and ready measurement!
As for maximum, there isn't one that most narrowboats could meet... many yachts using the system have their props many feet behind th gland, though longer runs (over, say, 15") might be supported by a P-bracket additional bearing.
