Strick, I wonder if those were Non E-10 rated hoses that were mislabeled as E-10 rated?! If the boat sat for a couple weeks with E-10 gas in the lines, that might be long enough to cause that problem! I'd be inclined to complain to the place I bought them from, as a recall is probably warranted!
My old lines WERE E-10 rated Sierra hose installed in 2006, and never caused any problems, but just to be safe, I replaced everything between tank and engine a couple of years ago with genuine BRP stuff including the primer bulb, because I'd heard of guys blowing powerheads due to lean operation/fuel starvation from restrictions in the line. Now I'm REALLY glad that I replaced them! That can kill any motor, 2 or 4 stroke, but it's especially bad if you're running a pre-mix 2-stroke because you starve the motor for oil as well as gas!
There is a good message here: ANY TIME your motor suddenly loses power, check it out and try pumping the primer bulb before you just give it more throttle! If it speeds up after pumping the bulb, you may have an air leak in the suction side of the system, a weak lift or fuel pump or some sort of restriction, especially if it slows down again after you quit pumping the bulb! If it doesn't clear up and the bulb stays flat, there is a restriction upstream of the bulb. If bulb is hard there is a restriction between bulb and motor. Running a motor hard when it's starving for fuel can ruin your day (as well as the motor!)
Because of that problem, BRP developed special test equipment that a good dealer will use to check out a boat's fuel supply system on all new motor installations before they even run it. This test consists of installing clear tubing with a very sensitive vacuum gage tee'd into it between the boat's fuel line and the motor. They disconnect the fuel line from the HP pump outlet and install another long hose from the pump discharge back into the fuel tank to recirculate fuel. They plug in the laptop, turn the key on (but don't start motor), and then use the laptop to run the HP pump at max flow and look for air leak bubbles in the clear hose while they monitor the vacuum. It must be a VERY high flow rate, because my I-Command gage, which gets fuel flow from the EMM and remembers fuel used, said I had used 14 gallons during the test which only ran for a couple of minutes! The maximum allowable restriction on the E-Tec's during that test is 0.5"Hg vacuum. I eliminated a couple of 90 degree elbows in my system to get the restriction down to 0.35 -0.4" range. Denny
