Any one know where I would find the size markings on my prop? Or what size was fitted as standard to a Tohatsu 120?
"3515" is stamped on the boss on the spare, and nothing stamped on the one on the engine, both are ally. Neither are original as the previous owner was prone to using the prop as a depth sounder!
It seems that the prop was not changed when the engine was un-bunged from 120 to 140hp and I guess that it may take a bigger pitch. The extra 20hp gave about 3kts on top speed and oooooodles more accelleration.
