I have a brand new 18' Grizzly Tracker with a Merc 9.9 outboard, won it in a drawing. My question: the river I will be putting in is shallow with many rocks. I've been told to attach a pitchfork to the shaft to protect the prop from hitting the submerged rocks. Has anyone ever heard of this? And how would I attach it without welding it? I got the boat last summer, but couldn't pull it with the Mustang, so had to wait until I got a Jeep. I'm putting the hitch on tonight, and want to be in the water on Saturday. This motor has never been started, and it's been many moons since I've been boating. I'm a bit nervous to say the least!! Would the gas/oil from last year go stale? <br />Any help would be greatly appreciated.<br />~Ellie Mae
