It should be no issue to do.I have a 1985 375 VT with a Yamaha Pro-v.I have a sea star hydraulic steering in it.I got it cheap as i was in the boat biz.Retail the similar unit inclusive of hoses should run around $600 to $800 .Thats with a tilt column,ram and hoses. I had to use 45degree fittings to allow the engine to get full tilt upward to clear the transon and that is with a fixed 3" jackplate.You can get a Baystar which is the low budget version for about $150 less.It depends on where you get the parts on what your going to pay.Do some shopping and you can save money.
Spring for the extra cost for the tilt column as it is worth it.
In any case it can be done and is well worth it.
