When the lower unit of my TRS outdrive was found to have a substantial crack in it many of you offered valid suggestions...thanks again.
I chose to purchase a used outdrive unit off an earlier model because not only did I get the whole outdrive, but also got everything from the Merc Trans II and back...through to the outdrive, including two of those pesky electric shift motors.
Everything is installed and working... that's the good news. I've just now noticed (duh) that the spline count on the prop shaft of the replacement is 19 vs. the "standard" 15 spline. The prop is stamped some monstrous "20-17" and looks like something hanging off the fantail of the Mighty Mo.
Question. How does this change things for me regarding prop selection. Initial searches suggest these 19 spline props are difficult to locate. Do you guys have any experience with them? Am I destined to run 25 MPH using this former fishing boat unit??
Please tell me it's NBD and where to look for a good replacement and suggested sizes considering the 19 spline requirement that will perform as we expect.
Many thanks ,
