Subject: Stern wave for R-21/25/27 vs. R-23 outboard
When motoring at speed in my previous R-25 (Classic) and my R-21EC the stern wave can get quite huge. Last weekend I motored at speed in my R-21EC and was quite surprised at the size of its stern wave.
Looking at R-23 outboard model running at speed I see that its stern wave is very small to non existent compared to what I've seen for the R-25 and R-21EC. I presume this is all related to the hull shape and maybe propeller size. The R-23 outboard's propeller is vastly smaller than for the R-25 and R-21EC and can spin up to be more than 1500 RPM higher.
I find that for the R-23 outboard having a much smaller stern wave is beneficial in that the stern wave encountered by other boats is less severe and less likely to cause them any alarm.
