    Xlt1200 Mr-1 conversion

    After years of research and several blown 1200pv motors I've finally started my Mr-1 conversion and chunked the 1200 in the scrap pile. This is a 05 Yamaha Xlt1200 the donor is a 05 Yamaha Fxho with only 31.7hrs I picked up from a local auction for $2500. So far I have installed the Fxho fuel tank, Fxho midwall bearing/coupler, and mocked up the Fxho seat plate to be able to easily access the rear of the motor and the coupler.

    Everything I've read up until now has said its necessary to clearance to starboard stringer to make room for the ho exhaust. But during mock up I found the exhaust has a little over an inch and a half of clearance which I would think should be more than enough without cutting it. So I believe I'm just going to bolt the engine right in as it is and see how it turns out.

    Next up I will be installing the Fxho transom plate/pump, Fxho cables/hoses, full oil change on the motor, and install the motor. Here are pictures of the donor and my current progress.Click image for larger version.

    This is the ski I'm performing the conversion on. Spent a lot of time and money on customizing it before the last 1200 blew so I couldn't help but stick with it and just do the conversion instead of replacing the ski.

    Nice looking ski. Could you get a measurement of the complete MR-1 from coupler to furthest forward point? Looks like you've made good progress already. Keep it up!
