All electrical motors will draw more current when starting especially when loaded. For this reason, a lot of circuit breakers will have a time delay before opening to allow for higher than normal starting current. You may want to replace your fuse with a slow blow fuse that does the same thing. All things being equal, fuses will always blow before circuit breakers because circuit breakers are mechanical and fuses are not.
Hard to say if you need new motor, if your starting current is enough to keep blowing fuses, you landing gear may be binding a little or you may have loose or bad connections/wiring. The less load (resistance)it is trying to move, the less current it needs to operate.
The only way to truly tell is find out the power rating of your motor and test it unloaded and loaded to see how many amps its pulling.
If you know for sure your landing gear is operating normally, and your connections are clean and tight, than its most likely your motor
