Hey guys, I've got older Yamaha F-100's (twins) with the basic yamaha digital tachs and wanting to get flow scans or something similar. What do you guys recommend for brand and ease of install?
I think the newer tachs have an option for gph? Limited on dash space so if cost of new tachs not prohibitive would consider that route as opposed to more gauges.
Does someone make a single gauge gph meter to switch between motors?
