What is the reason for this bolt?
What purpose does this bolt serve? I am on my 3rd intake duct since 1997, and the second one that just cracked did not have one in it. The only duct that had one in it was the original I guess, I don't remember. I did not take it out and put it in the second duct. ?????

plus when the bearing goes bad it marks a groove in the driveshaft-seems like that would slow you down- mark

I have not ran a bushing since 99 or so. In the service manual there is a bushing and an oil seal. Your actually supposed to pack grease in there. What is the purpose of this grease, bushing and oil seal?

I went ahead and ordered the 2 oil seals, bushing, & spacer. It must not be too critical, but it is there for a reason.

Its there to wear the driveshaft
Probably to keep the driveshaft straight

In 99 I did not even have a service manual. I just had a little book that had all the torque specs. The parts I just ordered got thrown away with the cracked intake duct 8 yrs ago.

I always thought that the seals and grease were to give a barrier to keep water from exposing the rear side of the intermediate bearing from corrosion.

and the little bushing was to help the water flow around the hole better giving less cavitation before the prop.
