I was skimming through the engine troubles section of a classic aquasport forum. Came across this buttercup of a post. The posting member couldn't figure out why the water pump impeller was stuck to the base plate. So he decided to "cut the side props to relieve the pressure."
But when that didn't work his next step was to torch the impeller to the point that it melts away from the shaft. Smartly, before torching, the member posted this picture and asked other members for suggestions of how to remove impeller.
Luckily another member chimed in to point out what should have been obvious, even to an amateur mechanic. But then again, this assumes the amateur mechanic is guided by the service manual. Oops.
Now I wanna know the result of his woodruff key removal. An epic debacle??
The above is just a friendly example to my fellow amateur marine mechanics reading this thread who do not own their engine models service manual. You are not trained in this skilled profession. Just because you've worked on your lawnmower engine successfully does not imply this expertise will translate to repairing your outboard engine.
Service manuals are necessary. Even the pro's use the service manual for an engine model they are unfamiliar with. The SM does not include every little detail. Those missing details are commonly found here, on this forum. If you don't have your SM why are you touching the engine? Hover over it, but tho shalt not touch.
Do you and your bank account a favor. Invest in a Yamaha model–specific service manual. You're welcome.
