Lower unit? on 1970 Evinrude

[BMC]

I had my prop on my 1970 60hp evinrude motor<br />stolen. I went to my local dealer and bought a new prop with thrustwasher and spacers. The shaft is too long. So I went back and they gave me another spacer. They said that<br />I have a different lower unit. So my question is how do I find out what lower unit I have? Is there anyway to measure the shatft to get the right Prop? The dealer would not tell me any info. I took the motor to them and they still didn't Know. Any info would be great.<br />Thanks!<br />Joe

That is strange. I thought they were pretty much standard (L/U i mean).<br />The only sugestion I have is to try the nearest prop rebuild shop. The "Yellow pages" is a great place to start. The internet is a great place, but they will want to see the shaft it's going on. I hate it when the mutants come out to play!!!<br />They do that because they know how easy they are to lift, and how much they are worth. You may find your prop in a nearby pawn shop.<br />I hope you get her back on the water soon.

Hi BMC, My guess is that the lower unit on your motor has taken from and older motor. I have seen that only a few times. OMC made a spacer that was probably three of four times thicker than the one you recieved from the dealer. According to the book you should use a 315810 spacer on your motor, however there was an older gearcase that used the thicker spacer. Adding one or two spacers should not give you a problem as long as you can tighten the prop so it does not move along the shaft, and can install the cotter pin.

Thanks for the replies. On my shaft I have to add 3 spacers to make it work right. will<br />that hurt anything. And I do believe that 315810 is the the spacers I am using.
