Propeller Line Guard

Rated 5.00 out of 5 based on 2 customer ratings
(2 customer reviews)


Protects your outboard motor, propeller and skeg.

Don’t pay for unnecessary repairs to your outboard motor, propeller or skeg.

Let’s face it, our lakes and oceans can get shallow really fast. Not to mention the always-annoying debris. A small investment can save you money, time, and frustration. Spend more time on the water and less in dry dock.

Protect your Investment!!!

Don’t be surprised if your fellow boater drops by and asks a bunch of questions. I recommend you grab 2 beverages and tell them all about it. Who knows, this could be the start of a great friendship.

    I bought a prop line protector guard from you in November 2018 and I like to say it was well worth the money.
    Last Sunday I was on the fraser river and I hit a log that was under the water and it worked great no damage to my prop and no damage to the guard.You have a great product has already paid for itself and I would recommend your prop guard to anyone who does not have one. it was no problem putting it on. would have had to replace the prop if the guard was not on the motor. anyone that does not have one on their boat should get one it is well worth the money. FIVE STARS FOR SURE

      Hi Dean, thank you very much for this great review! We are of course very happy it saved you from a costly boat repair. Not to mention the possibility of losing your primary drive in a moving river.
