I've read about your project and will be in line for your adapters. I'm surprised no one has made them yet. It seems like a product that would have a decent market.

I believe most who have Volvo drives have settled just to use props that are readily available. Jeff Hall & I thought too that there would be hubs to adapt Merc props but nothing was available. I located a shop here in the Detroitt area that makes most of the adapter hubs for all props but they felt the market was not big enuff to produce Volvo 17 spline hubs to Merc. The adapters should look like somthing like this one. Mark

Do you have any ballpark price worked out yet?

We were hoping to be around or under $100.00. I may be able to cut a deal when were done with the hub manufacturer but that wont be till after the engineering & testing is done, soonest next spring???

I came across this pic of TMITCHELL's Maltese trasom looks like he has Volvo SP drives?

Yes it does. Thanks for the pic

Some update pictures: Cleaned off the outside of the transom so it will be easier to clamp the new transom wood when I get to that point, and I cut out the rear cockpit bulkhead foe better access to the engine compartment, then
i pulled the cockpit sole up, next is removing the fuel tanks.

Tomorrow is 3 weeks since I picked her up in CT.

Your moving at a good pace for 3 weeks...............as far as the tanks go I would replace them if there original! ......My tanks (original 37 yr old very pitted but not leaking)
passed a presure test but was advised that the fatique factor in the aluminum will eventually give way sooner than later. Yours are 42 yrs old and if original why take the
chance when underway and pounding she'll crack on you........Plus, pulling the tanks without damaging them is a finesse thing..........when your replacing you can just go
at it!.............I used long sawsall blades to cut the foam.......it's tedious, but it works well. If you intend to save the tanks I would stretch a wood plank across the stringers
just to stand for leverage and also from stepping on the tanks.

When I got my Magnum it still had the original Volvo cut outs, along with 179 other holes in the transom. being a Volvo guy I was looking into early version trim Volvos but parts are for those are made of unobtainium. To get the trim I decided to go with the later model SP drive. With that I still have the option to swap out lowers for DP if I want.

This is my thinking exactly, I was going to make a trim setup using Mercruiser parts, but when I started adding everything up it was cheaper to just go with the SP transom collars. As it is now, I have 1700$ invested in both outdrives, and still have a 350 Chevy bell housing / PDS and a Y pipe for the exhaust as well to sell (I see them listed on Ebay for 400$ and 300$ respectively) and I'll scrap out all the aluminum from my original drives.


That said, is there any way to mount a tie bar or Hydraulic steering to the SP drive? Ive seen plates on the old 270-280 drives, but not for the SP/DP type.
