"Looking for assistance with a problem with a 1985 'rude, 30hp, Model # E30Telcoa. Have a knock that, if it were a car, one would think it is about to blow a main bearing. Have not hit anything: Pee stream is very strong. Knocks ONLY in forward; faster one goes, louder knock becomes. In reverse there is no noise, no matter how high rpm.

Was told problem is probably in shaft because all noise transfers up shaft to powerhead. No lub leaks....Help?? Many thanks!!"

(Piston Play Check)
(J. Reeves)

This procedure will tell you if there is any wear or play in the Wrist Pin, Wrist Pin Bearing, or Connecting Rod to Crankshaft area.

Remove the spark plugs. Insert a screwdriver, dowel, punch, or some object of your choice through the s/plug hole and into the cylinder/piston area. Hold the tool lightly against the top of the piston. Turn the flywheel by hand, bringing the piston up to top dead center, then continue turning the flywheel to pull the piston down about a inch..... all the while holding the tool lightly against the piston top.

Now, at the point whereas the piston has been dropped down about a inch, grab the flywheel and hold it firmly. Now, push that tool solidly and firmly against the piston top.

If the piston moves without moving the flywheel, there is a problem (wear, play, clearance, etc) somewhere with the items mention in the first sentence. Be sure to check all of the pistons/cylinders.

Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay store at:
