    I made up some new (off and old design) 1" prop shaft log seals. They are made from 6061-T6 aluminum with a machined finish. They are 2 1/2" diameter by 2 1/2" long. There is a pressed in 2" dia. double sealed bearing with the inside diameter honed to 1.002" (to slip over your prop shaft) its also held in by a snap ring for safety.

    Inside there is a double lip cup seal to keep the water out and a grease zert on the outside body to grease the seal. A standard size 1 3/4" hose fits from the rear, I also added rounded grooves to help the hose clamp bite into the housing and not slip off.

    With this design there will be no more prop shaft wear of bushings to replace because it rides on a bearing.

    I'm selling these for $89.00 + $13.00 shipping. Let me know if you would like one. I am also have 1 1/8" diameter prop shafts seals if your interested. Thanks

    The one you made me early last season works great; many races, lot'sa RPM w/zero defects. What's the difference between the new & old anyway?
    Thanks

    Hey Dimarco21. I got one of these from you a while back and I was wondering how much grease needs to be pumped into it? I feel like I was pumping in a whole lot when I installed it. Should I just keep pumping grease in till some comes out of the seal?

    I've been asked this question quite a bit and have always answered it in PM's. Maybe this will help but putting it on the forums.

    This is how I do it for my own boats and Tony Leaman's race boat that I help out on. I'm not saying this is the 110% right way because there is lot of different ways to do things but this way works for me.

    Installation: Remove old shaft log seal. Keep prop shaft in boat. Deburr end of prop shaft on outside diameter using a file or stone. Flatten out old set screw burrs on prop shaft using file or a stone and finally some emery paper. Remove all sharp edges from keyway so it will not damage the grease cup seal in the shaft log seal when installing.
    After prop shaft is fully deburred apply some light grease or WD-40 to prop shaft to help shaft log seal slide on easily. Slide the shaft log seal gently over the prop shaft taking care not to damage / cut the grease cup seal. Slide to shaft log seal into the rubber hose that is attached to the shaft log in your boat.
    Reattach prop shaft to v-drive then tighten hose clamps on rubber hose to shaft log seal. This will let the prop shaft log seal follow the prop shaft instead of being crooked inside of the rubber hose.

    Greasing: I use the Lubrimatic blue/green in color marine grease. Place v-drive / transmission in neutral. Using a grease gun. Give 3-4 shots of grease into shaft log seal. Then rotate the prop shaft by hand a few times. This is dragging the grease around the grease reservoir in the shaft log seal. Repeat this process until you feel resistance on the grease gun. Meaning the grease reservoir is full. You can NOT over grease the shaft log seal. All excess grease will push pass the grease cup seal out of the bottom of your boat.

    How Often: On my cruiser I grease it before every day trip. On Tony Leaman's race boat we refill the shaft log seal every pass. You can't over grease it.

    Hope this help answers any questions, Thanks again to all who have purchased my seals. Phil

    Excellent. Thanks. I was worried about over greasing it. So far it hasn't leaked at all so I'm very happy with it. :thumbsup

    Phil... Did you get the shaft seal mailed out yet? I have the transom hardware all cut and drilled ready to mount. I just need to polish and anodize before final mounting. I want to do all the polishing at one time. Hopefully will get a better price if I do everything together.
