Cobra 357 Sea Viper
I'm looking for information on rigging & set-up of a 357 Sea viper center console with triple 250 Yamaha's.
i.e. Motor centers, mounting height, shaft length, props etc.
The current set-up is 25" shafts each mounted on 2 CMC power lift jack plates bolted together, The center motor is 5" higher than the outsides. The outer props appear to be Mazco Re 4's or Hoss Hyperdrives (29" pitch) and the center has a 29" pitch Mazco OS cleaver. The boat currently tops out at 72 on GPS with the motors turning 5600 RPM and requires positive trim to get the boat to run level. I am considering replacing the CMC's with a Portabracket which will set the engines back 6" more which should help to make the boat run level with less or no positive trim. If anyone has any experience with these hulls or knows someone who has one that would be willing to share some information I would greatly appreciate it.
Thanks
