I've got a Sea Ark 2272 Super Jon with a Mercury 135 Optimax (both jet and prop capable with CMC transom power lift) now undergoing several performance mods. I'm looking for advice from the many extremely knowledgable and helpful folks on this forum, regarding extending the roof of the jet tunnel (tunnel install currently in work, not a factory tunnel hull) 10" aft to close the gap between transom and jet leading edge intake left from the 10" setback on power lift. My reason for wanting to extend the tunnel 10" aft of transom and between new float pods (also part of current modification) would be to close that gap then left between pods. Has anyone here done this when running both a jet tunnel hull (as opposed to boxier prop tunnel) with float pods installed as well? Doing so will close the gap between the trailing edge of the tunnel/transom and the front of the jet foot, which also increases "flat water" available to the jet. I'll post pics as they become available, but hopefully I am explicit enough here for solicited input from those "in the know". Thanks in advance and "cmon spring" already, enough of this pathetic quasi winter/ breakup condition!
