You might try running a search, I think there are several posts on how to do it.

I have searched but they skip my year model.

When I converted my 1988 60hp Johnson, I used the pump from an older version of the 3 cylinder motor. PN 0385784. You have to remove the pulse limiter fitting, and replace it with a simple hosebarb. I just wrapped the pump in foam and let it lay in the bottom of the housing under the carbs. Has been working fine for the last 4 years. If you have anymore questions just ask here, lots of great info on the board!

Thank you. Will a Sierra 18-7353 pump work?

Re: VRO to premix

That is the right style of pump, should work. That pump is for 20-30hp, it might not flow enough for the larger engine.

The gas side of the VRO can be rebuilt, if needed. http://www.maxrules.com/fixomcvro.html

I should have said VRO housing is cracked and need correct Sierra manual pump part number.
