Mercury 25 Been sitting since 94

[Brim4Me]

I have recently purchased a Falcon boat powered by a 25 hp mercury. The person that owned it bought it new in 89 and passed away in 94. I bought it from his son who has had it sitting in his yard since that time. It hasn't been cranked, it hasn't been touched. I got the boat at a steal so I couldn't pass it up even if the motor doesn't work. I was wondering if anyone could post a checklist of things I should do to the engine before trying to start it up. I was going to check the carbs and probably replace the water pump but other than that I dont know what else to do. Help.....

Change the lower unit oil.<br />Clean out the fuel lines.<br />Replace the fuel pump diaphram.<br />Replace the fuel filter if it has one.<br />Spray some fogging oil into the cylinders and crankcase, then let it soak for a while.<br />Replace the sparkplugs.<br /><br />That should keep you busy.<br />Good Luck.

remove plugs and squirt some good lube into the<br />cylinders and turn the flywheel back and forth by<br />hand for a while, remove lower unit oil and install<br />a new water pump kit. carbs are most certainly<br />varnished up and will need to be rebuilt.<br />check all wires are in good shape, mix up some<br />fresh gas/oil and fire her up!<br />good luck,<br />M.Y.

Thnx guys for the advice, I wanted a good winter project to keep me busy and from the sounds of it, I have one. Mechanically I can handle most of those things, other than rebuilding the carbs. Thanks again.
