90 ETEC on a Potter 20 CC???

I have a 23 Hydrasports so I am an undocumented alien along with you (I have a SC hull picked out but have not begun work yet). The reason for putting the 90 on the Seacraft is that the boats were designed in the late 60's when outboards were no more than 300#. The SC trim angle, especially when adding a bracket, is affected by motor weight more than some other hulls might be. Your boat may not have the same weight limitations that the SC has because its a newer boat that is made for heavier motors, I really don't know for sure. I would guess that your HS 20 would work alright with a 90 but it's just a guess. I personally would not be willing to spend a whole bunch of money on a guess.
The ETEC V4's are probably more in line with what your hull was designed to use. There is also at least one advantage to the V4 models; the ability to use I Command gauges. Sweet gauges! There is also a new Mercury 2.1L 115 4-Stroke that is lighter than the V4 ETEC and looks pretty impressive so far (probably cheaper than the 90 ETEC too).
Good luck with whatever you decide and keep us posted (just post in Spanish so no one knows its really a Hydrasports, they'll never figure it out).
