[QUOTE="cwphoto, post: 366039, member: 14437"] I run a lot in shallow water, so want a spare. Always good to have a spare! Agree some good tach readings are necessary. Not even sure what max rpm numbers are though, as I can't find much about the motor. The original diameter is 8 3/8" x 8 pitch (from what I've learned here). The replacement is said to be a 9 x 7. Looking at the specs for the 9.9, produce one year later. I think that has an 8.5 inch prop, and need to see if this is an 8 spline or not. Seems like it should work. 9 inches would leaves very, very little room, and just about touches the cavitation plate. Certainly close enough for a branch or something to wedge in there. Troy [/QUOTE]
