Rep Power: 14
three blade prop
There is a noticable change in my 35hp engine''s rpm when the LectraSan MSD is activated. Short term power draw is in the region of 30+ amps depending on water salinity.
Under calm conditions, the same 35hp propels my Nicholsom 35 at a comfortable 5.5kt or a "pushing it" 6.2kt.
In adverse wind and short chop (as found in a 40kt summer squall on the Chesapeake), I feel lucky when I maintain 4kt through the water.
Must say I didn''t notice much difference when I switched from the original 2 blader to the current 3 blade Maxprop a few seasons back. Backing down is less wild, but things can still get pretty hairy if you don''t pay attention!
