any reputable parts store should have it .why did it fail? allignment issue or rear support mounts?these must be corrected first or the new coupler will go bad real quick.<br />drive needs to be removed first. disconnect whats needed to remove/lift-up/slide foward the motor,remove rear mounting housing, replace coupler,reinstall in reverse order,set/adj. engine alignment,install drive.

I think mine failed because of a problem in the upper housing. The boat sat unused for 2 or 3 years. The previous owner said he had problems getting it in & out of gear. I wasn't getting any water flow, so a rebuilt the water pump in the lower unit, now I found that the upper appears to have seized up. I cannot turn the shaft/u-joints by hand when it's in nuetral. I'm waiting for my #3 manual to come before I start anything. I'm a half a**, back yard mechanic, but I'm willing to give this a shot.<br /> Thanks for your help so far... and in the future. I'll keep you "posted" !!! Joe<br /><br />Bondo... What does the "SBC" stand for? Sorry if that a silly question!

Yep, back of the engine, which is in the back of the boat. Sorry, couldn't help myself. :D
