Re: F115 shaft length change?
Hi,<br />I'm not sure if there is a jack plate or bracket to mount so a shorter shaft outboard can be used on a longer transom (the reverse is possible with a bracket or jack plate for sure, like an XL shaft outboard on a Long transom).<br />Check for example here:<br /><br />
Link <br /><br />Unless You can find such solution I would personally just sell the whole F115 long shaft outboard and then try to find a newer replacement extra long (XL) shaft outboard (not neccessary a Yamaha - a Suzuki, Johnson or Mercury 115 hp 4-stroke may work as well).<br /><br />To the best of my knowledge You need basically a new F115 XL lower unit and that is rather expensive new unless You can find a second hand.<br /><br />The cost effective question and warranty question I can not answer (but on the first Q I think I know the answer...).<br /><br />I have a F115 (2003) myself, Long shaft, and I really like this outboard.
