That should tow just fine and you’ll hardly know it is back there. As long as it is under 3K lbs, trailer brakes are not essential but always nice and you can safely tow it at 55-60, longer trailers tow just fine at speed. Backing with a short wheel base, long trailer does require a good deal of skill to keep from jack knifing the trailer but go slow and practice.

Enjoy the SeaDoo - great boats! Yamahas are good too and a lot of rental places use them as they seem pretty bullet proof.
