Right at 6000 RPM? Wish I could get mine that close but I cheat anyway (I can hear George laughing already)

Now you already have my vote for the inner hull drain install and if you go into the 190 mods picture section, you will see several install examples there if I am not mistaken.

Now when I installed them on our old 210, it took a 1 inch wood bit and I went in far enough to install the drains (210's use 2 of them) but I did not install the one on our 190 and had the dealer do it on the first service Should be the same though as long as you have the correct sized drains
