I have an older motor on a 16' Ouchita bass boat.<br />During my last outing I noticed a power loss. I applied the choke I got a surge of power that lasted until I dropped the choke. Out of the water, With the engine running at no load, and a muff atached I got the same indications. I pulled the carb apart and cleaned it throughly with carb cleaner and compressed air.<br />Both needle valve and seat look OK. I also checked the fuel pump and it appears the membrane is OK.<br />I also replaced the plugs, which I do every two<br /> years anyway. I've replaced all fuel lines including the tank to engine line.<br />I have a carb kit but wanted to see if anyone has other suggestions before I tear it down again.
