Chinewalker	Hi 1611, 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). 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. 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. - Scott (www.pfs-ware.com/smith)	2001-09-24
