What kind of boat ? It could be bad bushing or bad bearing or the rubber stuffing tube .

The prop shaft is actually 3mm(1mm would be very tiny!)the shaking might be caused by misalignment of the universal at the motor/shaft link or at the steerable strut at extreme angle.

It should be 1/4".
The shaking can come from worn bushings but I'm putting my money on an out of balance prop. The props that come with the boats aren't very sharp nor have they been balanced. Hopefully you've kept the cable greased otherwise it can wear out parts quickly. They make a nasty noise when they need a lubing. Those boats were also notorious for the stuffing tube being out of alignment.

Right now I'll post on about anything to keep those RC Surfers off the top!

An out-of-balance prop can cause undue wear on the rest of the driveline and it's not good for onboard radio equipment either. Larger props like the ones on gas boats are worse just because they're bigger and be subject to having them being really far off. I used to do all of my own prop work and on some of the gas boats props I'd have to take a lot of weight off one blade. If the strut has a worn bushing in it that can also make the cable move around a lot.

Check the prop and cable for any slop as there should be very little to none. If that's reasonably good then it's a prop.
