[QUOTE="parsleap, post: 309249, member: 10275"] PSG-1 - thanks for the thoughts and insights. I had not thought much about the deflection issue and bearing wear. That would obviously be harder to overcome without some beefier transfer sytem that took that load for the pump shaft, so it might start to get unruly! I wasn't even going to attempt to spin them with the 120 mercruiser engine. Probably more like a 6 cylinder. Good to know about the pumps getting enough water to the engine. I've honeslty never owned a jet ski so I've got some learning to do. A guy was selling a yammie 1200 this past weekend around here. I tried to make a case to my wife that it really might be fun to own one (knowing I'd try to take it apart after we got it!). Or thought about calling him to go look at it, and taking a measuring tape! Ha! Definitely want to re-use the aluminum housing and not try to make my own like Ranchero - I saw that thread too... wow... to both of you. I was thinking belts and I was worried about the moisture. There are some very high end carbon belts that are supposed to be good, but the tensioning times two might be difficut. Anyway, I'm more of a powerpoint engineer than anything, but have good friends with welding skills.... so I'll keep at the drawing board and keep you updated! Thanks again! [/QUOTE]
