Unless it's something different than the rubber keel guard I put on my boat back in like 99 they are really easy to put on and considering I'm not rich i'd just do it myself. I think the video might help on how far down the hull to run it cause from what I've seen those things are so long I would want to go all the way to the tow loop and you'd still have plenty of protection way down the hull. To tell you the truth I can't remember how mine is stuck on there, it's never gave me a problem since 1999....I must've done it right cause I'm sure glad I've had it all this time cause in my book it's a must have to save your hull.
