a mulitengine seaplane can be "taxied" by differential engine thrust
the water rudder is not a great help
GRUMMAN GOOSE and WIDGEON aircraft don't have any water-rudder.
Directional control .... on the water .... is maintained per the use of "differential engine power".
That particular detail is one of the reasons why I like Joe BINKA's GRUMMAN WIDGEN simulation.
One can water-taxi the aircraft .... and even adjust the direction of watertaxi ..... on the basis of differential engine power control alone .... just like on the actual aircraft.
Using the current panel and FDE combination .... "IF" one want to taxi to starboard .... then one just needs to select keyboard commands "E" and "2" to reduce power on the starboard # 2 engine only .... then select keyboard commands "E" and "1" to increase the power on the port # 1 engine .... which then has the effect of swinging the simulation to starboard .... and then work to the contrary if one wants/needs to adjust the direction of water-taxi to port .... OR .... work between both lots of commands in order to control/manipulate the direction of water-taxi as one desires.
And to re-synchronize both engines again .... all one then needs to do is select keyboard commands "E" and "1" and then "2" .... and all's then fine/re-synchronized.
One also needs to control (keep down to the minimum) the speed at which one is water-taxiing .... for this to be able to work most effectively.
And .... when one gets "REALLY GOOD AT THIS" .... one can even start to water-taxi in very tight circles to port or starboard ;D
Sadly .... I've not been able to use differential engine power to the same effect with the GRUMMAN GOOSE simulation by Bill LYONS .... at least not without completely screwing-up the synchronization of both engines.
