I took my 64 out for its first voyage since doing a frame off and noticed that the speedo is not reading correctly.

I took the original 300 out and replaced it with a TH350. The speedo is reading about 13 mph faster than what I an really going. Can I take the speedo gear out of the 300 and put it on the TH350?

Thanks,

Jim

I think you will have to change the gear on the output shaft to correct your seedo.

That address doesn't work. Is it correct?
