I have a Model 30 Kiefhaefer Corp. Mercury with Serial #1084198 Is there anyone out there that can give some me information on it. I would like to get some kind of a manual for it.
Hi 1611,<br /> The Mark 30 is a great old motor. Lots of kick in a very compact package! You can get a manual and just about anything else you'll ever need for it from Grubb's Marine (www.oldmercs.com). <br /><br /> The weak point on the Mark 30 was the lower unit, as it was more or less the lower unit off their 10/16/18 series with a beefier driveshaft. The gears were the same and they were borderline able to handle the power of the 4-cylinder 30. Add in a little abuse via a dinged prop or a little water in the housing and you've got problems. Keep after the unit by checking the gear lube frequently.<br /><br /> I would change out the water pump impeller as a matter of course, following the directions in the 1965 and prior manual from Mercury (Grubbs has it). The impeller is cheap insurance.<br /><br />- Scott (www.pfs-ware.com/smith)
