Help ! Buying a 1985 140 v4 Evinrude

I'm buying a boat and motor off a friend. 16.7 Scorpion by Chris Craft with the 140hp motor. <br /><br />The Boat has been sitting about 4 years in storage. Other than pulling the cover off I haven't had a chance to really look at the boat. The lower unit was drained and filled prior to storage and covered with a plastic bag to seal out any elements. (boat is kept on a marine railway under a car port.<br /><br />Any suggestions on what I should check before finalizing the sale?<br /><br />I've heard there can be problems with electric shift. Does this motor have this feature?

Hi Tommy,<br />Before final sale you should (if you can)test drive the boat. This will require some work but it will give you a better idea as to what you are buying. After you test the boat do a compression test on the motor. Do not be too concerned as to what the numbers are but be more concerned with how much of a difference there is between the compression numbers.More than 15 pounds is not good. Generally the psi in the cylinders should be 120 to 100psi. Greater the numbers, is a good thing.

Tommy,<br /><br />The compression test is a must. However, do it before you run it.<br /><br />DO NOT run that engine with any fuel that has been left in the boat.<br /><br />Monitor the head temperatures very carefully. You should be able to hold your fingers on them for of seconds without getting burned (145 degrees).<br /><br />The engine will DEFINETELY need a water pump service.

Thanks for your help.<br /><br />I did the spark plug and Oil thing. I pumped out the old gas then poured in some fresh and I test drove it too. and should have thought of a compression test before all of that but I got stupid. <br /><br />I have the boat in my driveway now. spent some time looking around, cleaning things up.<br /><br />The previous owner took out the oil injection (well plugged it) said it wasn't worth the risk of a 3$ part messing up.<br /><br />The idle is a little off. I have a partial (photocopied sections) manual for the motor, so I'm going to try to figure out how to set it, but I was reading some other posts about a Carb rebuild. is it difficult?
