I hear ya, but the tube isn't always dead centered itself so if you are centering your driveshaft in the middle of an off centered tube it's not going to work out so well...
I agree with this ^You got promo pricing and a sick free paint job just like I did. I think a few bumps in the road were to be expected with the first few hulls and that's part of the reason for the discount. I'm happier than a pig in with mine!
I've never understood why centering in the hole was important AT ALL, since it doesn't follow the type of process one would normally use to mount a pump in anything else (I work in power plants). You first mount your pump since the location is generally fixed by say pipework (or in our case the tunnel). Then if there is a midshaft type situation, or a gear box or something you algin that to the pump, then you align your driver (electric motor, turbine or whatever).Also, the drive shaft wasn't centered left to right in the bulkhead hole. But when centered, the midshaft wouldn't align... So on my second try, I let the drive shaft sit where it wanted, and slid the midshaft on. BOOM, lined up. Every how-to I've read on this site says "center the drive shaft first". But, and Steve and I discussed this, if you use the midshaft as a guide to aligning the driveshaft, it works great, just don't torque the midshaft into place, it has to float freely in the correct spot.
Once again, just basic little tips for people who have never owned a AM hull on some things that will help.

lol it's 12:30am (in Texas) and there's 8 people reading this thread. Go to bed people!
I'm not saying to install mid shaft first, just to put it on and get a basic idea of the area you want your driveshaft to be in the hull rather than spending time getting it dead center to find out it's in the wrong place for the mid shaft to bolt up. I've never had to shim a mid shaft, how do you get it to seal to the bulkhead? Silicone?brian I thought you knew better than that. Gotta start with the pump in first in my opinion, then once you use a gauge to make sure driveshaft is centered slide the midshaft on but not all the way against the firewall. Check with a gauge to see if the clearance from the back of the midshaft housing is equidistant from the firewall. If its not even then shim accordingly. This step process is critical when installing pump shoe mainly and can be debated both ways on midshaft first or pump in first if hull has pump shoe already installed. The way I look at it is the bulkhead/firewall could be off a little bit and if everything is not perfectly straight then buying bearings will be your new hobby, ask me how I know

Centering in the hole really serves no purpose other than looks, if it dosen't rub it doesn't matter (even if it does a bit I'd probably clearance it a bit). If you try and center in the holes you may end up misaligning your midshaft bearings since the mounting of the midshaft is pretty much fixed.
Honestly I feel like centering it in the hole is just some misinformed internet crap that's been repeated too many times.
As for your comments about the minor issues, I agree, its nice stuff to know ahead of time if only to make sure you have everything you need to deal with it. I had similar little issues with my ROK (like needing to shave the back of my intake grate since it overlapped with the ride plate, or not being told to order the extra long RRP pole tubes or having to chase resin out of all the inserts). Fortunately it was stuff I could deal with but I was expecting a bolt together ski.

Didn't mean you specificly, your process actually works.. Seen plenty of instruction on the internet to "Shim till you center it in the hole then slap the midshaft on" which really takes no account for bearing alignment.In my post I didn't just mean center it to just have it look centered, mine is more about when installing a pump shoe and at that point you need to make sure shaft is 'centered' so it doesn't rub. Also usuall a jig is used on the bulkhead to align the 3 bolt holes for the midshaft and its 'usually' when the jig is centered on the Shaft tube, So again centering the driveshaft helps.

He shouldn't have offered the hulls if they were not perfect. Who cares if they were discounted.
