Installation was easy. it only took 5 minutes while standing in the water at the boat launch. Ok, it would have easier on dry land.
Note from a boat repair shop: Keep up with the lock!!

this is for the guys who wrote about prop lock, it seems to me that it was to easy to install, did either of you have problems with it coming loose after awhile, i just bought it and put it on, i guess i`m just scared it will back off and i will lose my prop.

Rated 5 out of 5Â by TeamAdcahb Still works great...
I bought this lock for my Tempest Plus prop about 1 year ago. I leave it on the boat at all times. This lock does not hinder the performance of my boat in any way. After a year of use it still looks like new and it works great too. I only use my rig in fresh water so I don't know how it would hold up in the salt. For fresh water use I give it 5 stars.

I got one of these for my yamaha motor about one and a half years ago, and it works very well. I use it in and out of the water, and it has held up great. Now I don't always worry about losing the prop to theft.

If you have this lock, how is it protected from thieves? If they are the Pro's, could they have a key to fit the lock or are they totally keyed different to eliminate this problem?Answers
A:Â
looks like there are many different keysA:Â
If thieves try to steal the prop, the stainless barrel of the lock/nut just spins, no matter how much they try to wrench on it. You have to have the McGard key and socket wrench to remove. You should keep your key with you not your boat. No worries about different keys.1 of 1
