You'll need two. One kit per pump. Keep an eye on the gaskets. There are two slightly different versions. They're two-stage pumps. There's a small and large chamber. One version has a rectangular smaller chamber, the other is oddly shaped. The diaphragms and check valves are the same. Diaphragm kits don't include check valves, but those hold-up very well. You don't usually need them.
Merc1000 may be older than the guy in the shop.<br /><br />But if you give him the HP and serial number he should be able to do it.Just like newer motors.It's there on the screen.<br /><br />DHP

He's like ' oh, has that model got 2 pumps?? well you'll need another kit then, won't you?<br /><br />aaahh....yeah thanks pal!<br /><br />DHPMARINE, i think you might be right, and also i think he might be newish to the store.<br /><br />cheers
