Going without a clutch to start at least. I pretty much always was standing in the water when driving the last RC boat so running into the dock or wall is not really a problem when trying to catch it. I can also just hit the third channel on the remote to kill the engine when im done.
You can also just backtrigger/brake the throttle and close the carb. This is what majority do and it may save your new engine from a early grave.
Don't use a cable.
Solid linkage and you remove the carb idle screw and the servo maintains your idle. Your radio trim sets the idle. That way when you set the backtrigger/brake up so it just closes the carb and the engine dies. You don't want to get in habit of 3rd channel remote ignition engine kills because you want to slam the carb closed at the first hint it is going to wipeout because if you ingest one drop of water in that new motor while it is still turning even one iota you will twist the crank and basically have a $500 anchor/paperweight.

The more electronic junk you put in a boat connected to the receiver or battery is one more thing to get ruined by water and/or otherwise short out and meltdown the entire wiring from the device to the battery and and other wires that were laying together with the wire that burned will be ruined also like the servos. The radio will do almost everything a remote kill will do except in case of total loss of power and if you use a coreless throttle servo the integral carb throttle spring is enough to close carb at loss of power. You can just set the failsafe to backtrigger and when you shut off transmitter it will close carb and kill the boat without an iota of extra wires or electronics.
