Okay, just got back from the Copper bear hunting with the 1875 J-Max.
First off the boat only had about 4hrs. on it when I left so I'm not sure what to expect after it gets broken in or if mileage and perfomance should get better with time. I would think so.
I initially ran down for one hour at 8000rpm and filled up. It took 6gal. to top off. Speed ranged from between 24mph-30mph but we had serious head winds of around 30mph so I know that had an effect on speed.
Load was two hunters and more gear than I care to admit taking. I would guess we had about 300lbs. of gear.
Took a couple wrong turns on the river into some really shallow stuff and kept waiting to grind to a stop but didn't even touch so was happy with how shallow this thing runs.
The one thing I will say about this boat that I think is a big plus is how quiet it runs. I can sit right over the dog box while running and hold a conversation with another person. Granted we needed to talk loudly but it is no where near as load as the Opt. This for me is a big plus.
On the trip up river I ran it at 9000rpms and the boat seems to run awsome in this range. It probably was burning close to 7gph in this range but speed coming up the Copper was averaging around 25-26mph with a load and bear might I add.
I get the impression that this thing will probably burn the reported 3.5-4gph in the 7500 rpm range which for me is not fun enough. I am sure I will be running in the 9000rpm range most of the time so will suffer a higher burn rate than I had hoped for.
I still have a lot of testing I want to do with this boat and will start recording data with gps and burn rates once I feel it is broken in. My gut feeling is that the Opti is the better sled for the money and performance but after spending time it that boat last year was unwilling to put up with the noise level it puts out. I know some are breaking the code on this with sound silencing materials so maybe that was the route to take. We'll see how this boat does down the road. So far I'm happy with what I've seen but am hoping for better fuel mileage.
Whacked a nice bear way down by Miles Lake by the way. Oh, yeah. this thing did great even though after I pulled it out it had a bunch of sticks and debree stuck in the intake. The Copper as usual is full of trees, sticks, fish wheel parts etc. so it's like running a slalom course the whole time. Now I've got to go clean the boat and my gear as everything is full of sand from the high winds.. This must be what our troops in Iraq have to deal with on a daily basis.
