         7 . The boat drive according to  claim 5 , wherein the securing groove has a tolerance compensation. 
     
     
         8 . The boat drive according  claim 1 , wherein at least two attachment retainers are provided on the housing in an arrangement that is symmetrical with respect to a direction of travel. 
     
     
         9 . The boat drive according to  claim 1 , wherein an attaching part is received on the attachment retainer in a form-fitting manner, the attaching part being one of a fin, a wing, a weed protection cage, a Kort nozzle and a foil. 
     
     
         10 . The boat drive according to  claim 1 , wherein the connecting shaft is connected to a central part of the housing. 
     
     
         11 . The boat drive according to  claim 1 , wherein the attachment retainer is arranged opposite a position or at an angle to the position at which the connecting shaft is connected to the motor nacelle. 
     
     
         12 . An attaching part for a boat drive for driving a boat, comprising:
 a motor nacelle with a housing and a connecting shaft, wherein the motor nacelle is connectable to the boat by the connecting shaft; and   at least one attachment retainer configured to receive an attaching part in a form-fitting manner is provided on the housing,   wherein a groove is configured to be brought into engagement with the attachment retainer of the housing of the motor nacelle in a form-fitting manner.   
     
     
         13 . The attaching part according to  claim 12 , wherein the groove is of a T-shaped design and tapers in a wedge-shaped or conical manner. 
     
     
         14 . The attaching part according to  claim 12 , further comprising a passage opening for receiving a clamping, wherein, in a received state, the clamping runs through the securing groove of the attachment retainer. 
     
     
         15 . The attaching part according to  claim 14 , wherein the passage opening has a cutout for receiving the clamping.
