Loss of power envirude 1974 25 hp,

[jjl]

I got my lower unit put back together and fixed clutch dog that was slipping and went out yesterday.<br /><br />After 20 minutes at full speed, the motor starts choking down but still runs enought to get me back. I found I could close the choke some to get a little more power. <br /><br />After cooling off at landing I went back out and it ran good for about 1/2 hour then started again.<br /><br />How can I run down if my problem is fuel or fire?<br /><br />without grabing plug wires as I go down the river?<br /><br />Thanks in advance,

Re: Loss of power envirude 1974 25 hp,

Take a spray bottle of fuel mix with you.<br /><br />When the engine starts losing power, squeeze your primer bulb. If that gets her up you have a fuel supply problem, probably restricted venting of the tank.<br /><br />If the primer bulb doesn't help, spray fuel mix directly into the carb. If that gets her up you have a carb problem.<br /><br />If neither helps you have an overheat problem. Replace the water pump impeller and check all lines from the water pump to the block.<br /><br />Good luck.
