I have an old mercury 6cyl outboard motor. lower unit says 65horse serial #1809282?

Question

the lower unit says 65 hp. the front of cover says merc900 and the serial # is 1809282 (on the stearing arm) i think i need to change the impeller for water pump. could someone tell me the correct information about the motor based on the serial#. and if so is it a big job to change the impeller. and also the mix ratio for fuel

Answer 1

Go here to I.D. your motor; http://www.marineengine.com/mfr/mercury_... Also check the parts listings. They have a repair kit with impeller, wear plate and other items needed for about $15.00. Manuals are available there also.

Answer 2

Yeah I would agree with the other responders, they have given you good info, a reasonable set of hand-tools with the repair manual from Merc will get you through it, no sweat-by the way, I rec these be changed EVERY year if you store the motor out of the water, every other year if you store it IN the water.

Answer 3

That sounds like 1965 Model. The Impellar would probably be, # 47-89984T4.  It will cost you about 30 bucks.  You can order it here.  http://www.eastcoastmarineservice.com/lo...  While your at it. you should spend a bit more and get the dealers service manual.  It will be around $70.00

Good Luck
