Prop Set up on DP-A drive?

[bicounty]

I am piecing together my drive on a 1990 DP-A 290 drive .When I took the props off there was just a spacer ring in front of the forward prop, a locking ring and a nut holding the forward prop, then the rear prop and the cone holding the rear prop. Looking at the lower unit illistration shows I am missing Ref# 38 line cutter forward , Ref#38A plastic washer (front and rear) and Ref#43 line cutter rear. I don't have these parts and I am trying to figure out what I need to order. As I mentioned I have the lock ring Ref#41 and locknut ref#42 and then prop cone Ref#45 and a thick spacer ring that was infront of the foward prop.. I used the part numbers in the illustrations but a few of them were replaced with other numbers. The foward line cutter #853440 was replaced by a thrust ring part#3858547. The plastic washer ref #38A front part#853584 was replaced with a spare parts kit #854667. The line cutter rear ref# 43 #853441 was replaced by thrust ring part#3858458. I punched a few of these part numbers into ebay and when they came up the pictures look different than the volvo parts illistrations. The line cutters look like spacer rings and the spare parts kit looks like a 2 piece spacer. The guys at the parts counter can't tell me what has changed. Anyone have a parts list for mounting a dual prop set up?

If this is for a gasoline engine, you'll be using the B series propellers in aluminum, or the C series in SS.
All that needed are the correct washer type spacers for both FWD and AFT props.
When/if you find both line cutter/spacers as a unit, this works just fine.
However, the line cutters are no longer avaiable through Volvo Penta.
In this case, you'll use the spacers only.

The larger thicker plastic spacer ring is not used for the B or C series props.
This is for the Diesel engine props.
