I have a 99 187 Elite with the Detwiler Jackplate. I finally can now adjust this jackplate and have been playing with the height of the engine. I have not measured the prop to pad but have made a few marks and adjusted up a little bit. Went out again today and its running 55ish at about 5100 RPM.
98 `175EFI Merc. 25 Trophy plus. I did lose about 75lbs by switching to Lithium TM batteries. Its still getting 20PSI water pressure at WOT too.
I know the engine can turn 5500-5600 rpm and the boat should run 60-62ish. I previously have had the boat to a max of 64 MPH with the old LA batteries so I know what it will or should do. Is there a baseline Prop to pad that is recommended for this boat and engine? Thanks Brian
