Thread: Propeller Question

Diameter of the prop is too big.

This is a pretty good source of info. I think from your info on your prop it is a 19" prop. Should be able to determine what size your motor should have.

Also here is the Yamaha site for selecting propeller size for boat style.

13 1/4 by 19 should be standard prop. Think you asked this on another thread. I think you either have the wrong thrust washer installed or are missing the thrust washer. If you have pulled the prop does it have a washer between housing and back of prop? When installing aftermarket props some take a different spacer than stock. Since you bought this used anything could have happened when previous owner started changing props. You could pull prop,check for spacer, if missing you need one if not see if it has numbers. I would find the telephone number for Apollo and give them a call. I'm sure they can help you.

What Cray said

Thanks for the help gentlemen. I will try and call them Friday, I don't get off work early enough during the week to make it before they close. I did inspect my motor some more when I got home. There is a washer on there with the numbers 991212. Maybe I will get lucky and just replace a washer or something haha.

Acutally I have found 2 parts that my be referred to as the washer. The first one I referrenced is more along the lines of your typical washer (in shape). The properller would butt up against this one when installed on the motor. The second peice I have found slides into the rear end of the propeller and the nut tightens down against this piece when the prop is installed. These numbers read 826074.

With out pictures it's really hard to tell what you have. Basically your saying right now you have 2 washers or spacers between prop and gear housing? If so take one of them off, put prop on and see iff blade tips will clear tab. I would take out the thinner of the 2 first. Then try with the other one and do same thing. If you find one of them lets the prop clear tab then torque down and spin prop checking to make sure you have clearance inside housing and nothing is rubbing.

Sorry Cray, I should have thought to upload pictures. There is only 1 washer between prop and gear housing. Here are pictures. The second thing I was talking about actually sits itself down inside the prop and have grooves for the drive shaft to slip into. Sorry I'm not more descriptive/calling things by their proper names, still new to it all haha.Attachment 169635Attachment 169636Attachment 169637
