Hey thanks for the reply, It is good to have someone share an interest, the Boat is back in the customer's possession; after spending a little over $500.00 he was done, he developed clinched fists! Thanks for the links, that is exactly what was going to be replaced next. It had the 3.0...

Hey everyone, Just wanted to share a little story basically... Customer says "Noisy metal grinding sound at drive, and warning buzzer, also noticed a water leak at bottom front of engine." Metal grinding sound at outdrive (Gimble Bearing) Torn or Worn areas allowed water in the larger...

Spark Tester I found one and ordered it, this should definitely speed up the spark check process. I can't wait to get it and try it out. http://www.marineengine.com/newparts/part_details.php?pnum=CDI511-9766&ptype=&Engine=&Model= Now I am still searching for the best Tachometer for Boat...

Chris, I believe it says 2 or 4 cycle (not cylinders) Anyway, I was just wondering if anybody had any knowledge of it or maybe knew of one they used and trusted. I went to the link you mentioned... nice stuff. I was in Fort Collins, CO. one time and watched this guy test a multiple...

I am looking to purchase 2 tools and would like some input. (1) Wireless Tachometer (1) Spark Tester (capable of testing at least 6 cylinders at once) I was looking at this one, just don't know anything about it...

Beautiful sounding 4-stroker Hello everyone, Yesterday I got a chance to finish up the little 40 horse Yamaha, as suggested by Dave; the flywheel and crank were lapped with lapping compound (a nice dark grey finish) cleaned up and inserted this whopping .80 cent part that wouldn't let her...

So True, I have even preached that very rule to people I have trained (rule out all the simple things first) just do the basics. Guess I should practice what I been preachin' ! I'm glad it has been figured out as well, waiting for the key now, and anticipating the sound of this 4-stroker singing.

That's great advice Sir, I just so happen to have lapping compound; I have never performed this action on the flywheel to crank before, but it makes sense due to the tapered shaft for a good connection. I have seen thousands of sheared keys on walk mowers with blade directly on PTO shaft...

OMC 4 sure! Mercs are too finicky.

Problem found Well Mr. Dave, the problem has been uncovered :bounce: THE FLYWHEEL KEY was sheared and evidence showed that the flywheel had to have made a complete 360 after shutdown judging by the marks left on the crank. I want to thank each and every member that made suggestions and...

Service Manual has arrived I have been doing some studying and I am glad to have the specs that I need to get to the bottom of this mystery. :confused: With the ability to know peak voltages when testing and color codes to follow, it is just a matter of time now. :D The first thing I am...

A good Service Man should do all things needed, simply when you request a complete Service. Make sure to let him know that you have never heard it run. :)

I may take a look at it before the Service Manual arrives, no promises...will update. Have several things to check thanks to you guys.

Does fogging oil actually ignite? I did try carb. cleaner directly into carbs. and went so far as to remove each plug and spray some into the combustion chambers. Nothing, Nada, Zip! :brickwall: so, it has to be a timing thing, or a screwed up ECM. I also considered a problem with the safety...

I have also seen this, I removed the plastic cover to reveal the flywheel. I inspected the cogged timing belt, removed the plugs so to spin the flywheel by hand, removed the valve cover and verified TDC on Top cylinder. I was not 100% sure of the timing marks. So I decided to order the OEM...
