Hi Fishersak,
I have the exact same double eagle and do ocassionally use it on the Fraser. It can be done but you just have to be a bit more cautious than if you had the ideal, an aluminum jetboat. Here's a couple of pointers if you do decide to take the deep v fibre glass hull with outboard on the mighty Fraser:
1) Pick your launch wisely. Island 22 works for me. Some of the other launches may not be as good and you may want to check them out before commiting an entire day to a launch that will not work.
2) Two people are recommended when going out. One person to back down the trailer while the other person is in the boat and starts the motor, lets it warm up, and pulls away from the trailer. Then the other person parks the truck and gets picked up by the boat by jumping on the bow or over the side. Waders and a pfd are recommended.
3) A depth sounder is a must and it should be used at all times.
4) A river map with all the bars or preferably some one who knows the river is recommended.
5) You do not have to beach your boat to fish. You can anchor offshore and bb or barfish from the boat. If you anchor you want about 30' of anchor line with a float. If you hook a big spring you throw the float overboard, follow the fish, and land it (hopefully). Then you return to your anchor float, reattach and continue fishing.
6) If you want to fish from shore, rather than beaching your boat, pull in close, cut the motor, tilt it out of harms way and haved the second person jump out. Then hold the boat and anchor a few feet feet from shore without ever touching bottom.
7) When pulling your boat out the, reverse procedure to launching applies. One person jumps out and backs in the trailer. This is exremely important - make sure the trailer points downstream! Drive the boat on to the trailer and load as usual.
Good luck if you take the double eagle out. It can be done, it just requires a few more precautions than if you use an aluminum.
