[QUOTE="86tuning, post: 473087, member: 23006"] The stock impeller coupler has a bearing and seal. No different than what's done with the ski hull. Only difference is that I'm integrating the pump shoe into the hull instead of the bolt-in style on the ski. The pump does have trim, and I am concerned with efficiency, but there are too many variables to consider for drivetrain angle. So I'm running 'stock' 2 deg down for the pump. I hope it works. Also, planning on putting the fuel tank in the nose so it can be on centerline. Plan B is to put it inside the centre console, but that makes the console a lot bigger than I want. The bottleneck is to find a machine shop to cut small splines. Everything is dependent on it. Coupler position, engine position, yada yada. Cheers, Brian [/QUOTE]
