This is a used aftermarket replacement outdrive leg for the mercruiser Alpha one range. I acquired it as part of a job lot of mercruiser spares and therefore I have not seen it in use. Whilst it is secondhand, it certainly appears to work correctly, it rotates smoothly and goes into gear properly. Externally it is in excellent condition and appears to have been either used little or perhaps not kept in saltwater as there is no evidence of saltwater scale type deposits.
I believe it is 1.47 ratio as this would correspond to the number of turns of propeller rotation. The UJ is free and appears as new.
Please look at the photos and let me know if you would like any additional specific part photographed or a report about anything in particular. Please note someone has put Mercruiser stickers on this but it is a compatible aftermarket product.
