that sounds about in line.
Cutwater 26 performance

Juts got a 2012 C-26 with the Yanmar 180 HP with low hours. I was aware of the underperformance issue before buying it. After reading previous comments I wonder if any owner tried to install a larger propeller to improve speed? And did it work?Thanks, afjag; Go Air Force!

Bottom line is you want the engine to turn 4000 rpm + 100 rpm. The hull design is a tough one to get to perform. Believe me I have tried. I have the D3 220 hp and sometimes want to get the paddles out to help it along. ( not really) The boat empty will perform nicely. Add some gear, fuel, water, and a couple of passengers it's going to slow down. I have our boat loaded for cruising. I actually changed the cup by reducing it by .035. This didn't really help with speed but it helped to keep the rpm where Volvo recommends it to be 4050 rpm which is the same recommendation that Yanmar recommends.
I complain about the performance but it still does mostly what I want it to do. If I need to get somewhere in a reasonable time I can throttle up to 3600 rpm and make an average of 14 kts if I bump up to 3750 a strong 16kts. Put the throttle down and I will see 18.25 kts (loaded down) I don't run there very often but I can. I usually stick with 3400 to 3600rpm as a fast cruise which is Maximum recommended cruise speed for the D3 and the Yanmar. The C26 cruises very nice at 2250 rpm performing with great fuel economy and a solid ride in most reasonable water conditions. 3' or less.
Note: The Sea trial of my C26 when we purchased it new. There was nothing on board except My wife , myself, and the selling dealer. full tank of fuel, no water, black tank empty. 4130 rpm 22.6 kts this was with factory prop 17 x17 .105 Cup.
I have the boat equipped for comfortable cruising with added 22 gallons more fuel capacity, full enclosure, larger inverter, larger batteries, customized V berth, two TVs, Generator , grill, dingy with motor, freezer, paddle board, tools, extra parts.... That come with a price of over 4 kts loss in speed and a prop adjustment. I guess I should not complain.
