Hey I just picked up 50% more power with my 2gm20 18hp yanmar in Impaulsive #127. The exhaust coupling elbow had rusted more than 50% closed. It needed to be replace and cost 129.00 for the part. I also pulled out the heat exchanger and cleaned it with acid. I replaced the anto freeze with red perminate not green which can corrode the aluminum in the motor. PS I get 2.3 hours per gal now at 6 nk Paul |
