Against received wisdom the brass propeller on the Tomkat has been replaced with the original plastic version. Normal service has been resumed with the boat skipping speedily across the water even on a breezy day.
At the lake there was a group installing a landing stage. Several had also had the same experience. The quality of the castings appears very poor. While I had to ream out the hole to install the prop on the shaft, others had it slopping around ! Everyone felt that the casting was too long although I seemed to suffer less as there was about 3mm of thread to work with while others had half this.
So brass isn’t always best.
