Etec 90 prop help
The revenge	#1  Posted on 05/12/14 - 7:06 PM
Member Posts: 50 Comments: 0 Joined: 03/12/12	Today I did the shake down cruise on my 1970 16' custom Whaler. I bought the 2006 90 Etec used and it came with a SS prop. The prop is a Viper 13.75 X 15. #389949 Here's the performance I saw today with this prop. Half fuel, one person, very light chop. 25mph @ 3200rpm 39mph @ 5300rpm I'm pretty sure I can raise the motor one more hole. I'd like to at least get I to the 40's. Does anyone know if the stiletto 13.25 x 15 would perform better that this viper 15? Thanks

Your manual should tell you what the RPM range should be for WOT. See our article here: (Note: we need to add more to this article) http://www.whalercentral.com/articles...cle_id=108 You don't mention where the motor is mounted now.
