Hi all, please help 
I run a 15 foot CJR with a 1979 Evinrude 35hp twin. The motor starts and runs fine but has absolutely no top end power. She picks up well off the throttle and proceeds to a walking pace on full power. I've replaced the plugs, cleaned and reset the carb, checked the maagneto sync as good as i know how and checked the throttle and timing is fully open at full revs. It has a 13 pitch prop and the boat is usually carrying 2 men with tackle. I sold a 25hp Yamaha to buy the Evinrude and the Yamaha was twice the power. Has anyone any ideas ?
