1988 Evinrude 120 HP Bucks or Clunks

[snesbitt]

I mistakenly asked this question in another person's thread regarding a bad Clutch Dog, so I have opened my own question to validate my problem.<br /><br /><br />Good day - I have a 1988 Champion Bass boat with an 1988 Evinrude 120 hp engine. My engine seems to mimic the symptoms discussed here. As you throttle up to 2700 RPM the engine starts to buck and kick. Of course the boat will not go on plane. I tried multiple times, this is after cruising out past the bouys -- 10 minutes of travel time. We traveled at about 6 mph for a while and then shut down to fish. After a couple hours we were returning to port and I attempted to go past 2700 RPM and there was a buck but the boat dropped onto plane and the engine ran fine for about 5 minutes then it started bucking again. I dropped it off plane and limped home. The boat is slipped and the mechanic will attempt to test drive it this week. I want to be a smart consumer. <br /><br />1) Do these symptoms sound like this is my problem?<br /><br />2) What should it cost to repair?<br /><br />3) I have mid-range mechanical skills -- can I repair without specialized equipment and what time frame would I need?<br /><br />thanks

Sounds like your clutch dog may be slipping. They cost around 100 dollars. It would guess if you have a machanic fix it you will spend 500 dollars and that may be a low estamate.<br /><br />Some times you can turn them aound if they areint beat up to bad. Because in reverse you dont need much power and it will hold.<br /><br />You should be able to fix it your self. But only if you have a manual for your motor.<br /><br /><br />Good Luck!
