I have a S20 Bennington with a T50 Yamaha with the stock 14/11/3 prop and am not sure I am getting full power from my engine. WOT with two persons aboard is only 4800 RPM and that just doesn't seem right. Researching in other forums it seems that it is running about 1000 RPM low. Would others with the same boat/engine/prop combo let me know what your WOT RPM is? The dealer had a mechanic check it out and he said because the Bennington is so heavy I am getting all I can out the engine. I do not feel that is entirely correct and if others are getting more WOT RPM I could use this information to press the dealer into researching it further. Thanks in advance for any help you can provide.
