HELP PLEASE! 9.9 Johnson, water blowing out the exhaust

[SSSTANG]

I bought the engine today. It is an 198? but it looks new. When it is running, in a 55 gal drum, water dribbles out of the peehole but it blows out of the exhaust ??? ports on the rear of the lower unit. Is this normal? The guy I bought it from said he thought it sucked some trash into the water passage and stopped up the peehole. I'm hoping it isn't a blown head gasket or cracked case. I will check compression tomorrow.<br /><br />Thanks!

First, try to post the model number and serial number of your motor whenever asking a question.<br /><br />You can try to push a wire into the telltale peehole to dislodge any blockage.<br /><br />Yes, the water should exit the exhaust.<br /><br />I would put a new impeller in the water pump as they deteriorate with age. This may also be the reason you have only a dribble out of the telltale.<br /><br />Examine and change the lower unit oil, looking for water intrusion and excessive metal shavings.<br /><br />And new fuel filter and spark plugs.

Thank you for the reply roscoe.<br /><br />Model # 10R77A<br />Serial # 4630389<br /><br />I'm new to boating so I have a question. Why does exhaust exit the lower unit and the prop? and where would be the best place to get a manual for the engine? Could I replace the impeller without a manual? I'am mechanicaly inclined.

Not advisable to try it without a manual. Not that it's particularly hard to do, but it will guide you through the procedure and have pics to refer to. You can get a Manual at any Johnny/Rude dealer or Marine outlet(West Marine) or order one at the bottom left of this page
