[QUOTE="86tuning, post: 470246, member: 23006"] Well I'm slowly plodding away at the water inlet. In the meantime, I did find the service manual for the waverunner here: https://www.manualslib.com/manual/1058844/Yamaha-Waverunner-Xlt800.html?page=1#manual And it's been quite useful so far. I'm trying to put the engine as far back as I can, to increase cockpit space in the boat. The plan is to shorten the driveshaft and the intermediate shaft. And intermediate shaft shortening requires disassembly. The service manual is helpful for that. Short story is that the shaft is pressed into the bearing, and the coupler is threaded in place, and retained with pipe sealant. Also found the parts catalog for the waverunner here: https://www.yamahapartshouse.com/oemparts/l/yam/5003a4cef870021f60a13122/2001-xl800-xa800z-parts Apparently the 1100 waverunners use a shorter intermediate shaft. Make sense, as the triple cylinder engine is longer. But the couplers are the same, so I could use the 3-cyl shaft to move the engine back, and not have to shorten my 2-cyl shaft. If I can find a used one. But I may be able to shorten the 2-cyl shaft even further to move the engine further back by an inch or two. But that's a tomorrow problem. Cheers. -Brian [/QUOTE]
