I just purchased a 1985 Yamaha 220. I am in the process of mounting it on my 1972 Mako 22'. I'm doing the online resaerch to figure out as much about this motor as I can. I noticed, from Yamaha's website, that there are two different models: <br /><br />V6-SPECIAL_LK (1985 Outboard) [V6-SPECIAL_LK85-03-0469a]<br /><br /> and <br /> <br />V6_SPECIAL_XK (1985 Outboard) [V6_SPECIAL_XK85-03-0469b].<br /><br />Any ideas on what the difference is? I'm waiting on a Seloc repair manual (snail mail), but would like to get the ball rolling on finding information about this motor.<br /><br />Any other sites I can find more info would be appreciated.<br /><br />Thanks,<br />Bryan
