Ron,
Good luck with the new E-Tek 90 HP HO. I just purchased one today for my Montauk 170. Went back and forth between the standard 90 and the high output 90. The dealer really pushed for the HO, not that much more money, but because of the size and weight of the 170 compared to older Montuaks he thought it would be a much better overall performance fit. After much deliberation I decided to go with the HO. Did you mount the external oil tank in the console. Did you add an additional water separator? I haven't seen any posts with the 90 HO on a 170 but I will report my test results in the spring.
