I don't think the Tsunami will give me any trouble, a little water may trickle out on acceleration, but it is 90 degrees straigt up to the thru hull. I was hoping that water would force its way past the pump a little to help prime the pump. My rear bags are almost in the same exact configuration and I have not had issues with them.
The scupper....that thing is a pain in the butt to get off. I removed the four screws, romoved the large nut, drank a beer, tried to push it from the top and it didn't budge, went underneath the boat and tried cutting caulk without cutting the boat, drank a beer tried to push it from up top again still wouldn't budge, drank two beers to think about a new plan of attack, came up with a plan and drank a beer, forgot the plan of attack and started to loose interest in saving the old scupper; probably at this point I should have quit but I didn't want all that beer to have been drunk in vain so at this point I couldn't give a "pile of poo" and I jumped in the boat with a large mallet and a 2X4, 1 HUGE smack and the scupper hit the floor like a bolt of lightning I probably should have done a few test taps instead of an over the head swing at the 2x4 (I am going to blame the beverages for that one) . Oh well at least the scupper was out. Drank a victory beer!!!!
