I believe you will be VERY disapoointed with an E-Tec 3 cylinder 90 on a 170 Montauk. The engine is definitely not as powerful as whatever Mercury/YamaMerc you will be removing. the E-tec 90 has a very small displacement.
The boat can easily handle 115 HP, so if you want the same or more power then you already have, go for the E-tec 90HO V-4, which is basically 115 HP. But I agree the external oil tank is a real dinosaur now for this HP range, which may mean you need a 4-stroke, or a Merc 115 PRO XS Optimax with integral oil tank.
Going with Evinrude means new controls, and their huge control is unfortunate and not very pretty. If you stay with Merc, everything will hook up. Take a look at the brand new 359# 2.1 liter 4-stroke 90's and 115's. These are now going on the brand new Montauk 170's at the factory.
