I have an oildyne pump reservoir that is cracked and I need a new one. I have been told that they are no longer available through Mercruiser. This is the same pump that is sold to trim every bravo drive. I need the old style reservoir with a single bolt that holds it on from the bottom. The newer style has four bolts that holds in on from the top. I don't know if my pump has the 4 tabs or not. I will check soon. I just thought that someone has to have a few of these pumps sitting around.

Thanks!

Good Luck. I know it's mickey mouse but I have used Marine Goop to seal those cracks and it works great. Make sure its really clean if you try it.

Thanks Formula31. I may just try that. I don't have marine goop, but I wonder if 3M 5200 will work? It sticks to everything and I don't think oil will affect it.

Merc makes a retrofit kit but it is almost the cost of a new pump!
My pump was made in 1991. The new style bottle fits everything 1992 and later. Figures........

You can get an aftermarket res from Sierra. Up here we get Sierra parts at out NAPA store

if you buy the upgraded tank it will fit the early pump housings. did all three in my boat last year.

Biggus - thanks, I will see if Sierra makes the old style reservoir.

mrv8outboard - How did you attach them??? My tank and the new tank look the same. However, my tank mounts with a single screw going up the center from the bottom. The new style tank looks the same, but it mounts with 4 screws from the top. My pump is one year too old to have a place for the 4 screws. I don't have the 4 holes on the mounting plate. After 1992, the holes were provided.

Thanks!

Sierra does make the old single screw res. I repaced one on Friday.

my pumps were 1993 vintage thats why. like all have said your local napa store can get the old style.

Thanks!
