    generically speaking with a I/o you will want to keep the exhaust tube length what it is to help pop the stern a little more under accelloration and while at speed. Every application is a bit different as their are a lot of veriables but 4 stroke outboards along with I/o's tend to prefer all the vent holes plugged. It's been a while since i've worked on a hydromotive but i'm going to say this is a toss up. I would tend to push towards the bravo 1 though as the pitch progression is a little better i feel.

    I’m looking seriously at BBlades test program. It seems the current consensus is to start with 28P Bravo I with standard tube length and non-vented. I have appreciated the feedback.
