I have a 2002 T223 with a 2004 Yamaha F225. How much of a performance drain would you expect from putting up a bimini (which I did this summer). It seemed like I lost some RPM and WOT speeed with the bimini alone. When winter came and the rockfish bite was on I added full curtains. As it stands today with the bimini up and full curtains I can barely get to 5000 RPM (by trimming) with low 30's in speed on the gauge. How much performance should the the top and curtains drain from a clean boat? Trying to determine if I migh have some other problem going on or is this normal with top and curtains. Engine seems to run fine, no bogging, etc. The engine only has 115 hours and is equipped with a 10M fuel/water seperator.
