SkeeterStew,

Thanks for the info. My Sealoc manual makes this process hard to understand. I have a question...

"Measure the distance of the snap-on screw connector on the top of the control arm going to the metal thing under the flywheel with your dial caliper.
For 115 - 130 hp it should be 60mm, or 2.36 inches.
For 150-200, it should be 54mm, or 2.56 inches
for ProV200, 63mm or 2.5 inches. "

How is this measured? I had to replace a linkage that failed and they are like ball/socket joints. Do you measure from centerline of the ball parts? From the outsides of the sockets? etc? The one I am measuring is also shaped like a "Z" or N" . Any info will help, thanks!

Hi there Leaverrite! Good question. On the ball sockets there's a little "fin" at the halfway point. Measure to that. Halfway mark on both ball sockets. You may find it easier if you use a straightedge from the flywheel side down to the level of the other side, but it might not be as accurate unless you're real steady. Not that being 100% accurate on this part matters all that much.

Good luck!
