Yeah, rake not bend.
If there is any slop in that mast base, it might work. 2 degrees is very little movement at the mast base. BUT you don't want any constant tension on the pins or plates etc. from the rake!
So best to do as Dave suggests, ask Dwyer, clarify you need a couple degrees rake, maybe they have some other base or some options to address that.
cheers, John

I'd ask Dwyer is you can return your mast base and get the correct tabernacle for a M17.
Follow what Mark wrote - rake is different than bend.

That sounds like I then also have to shim my new assembly to introduce some rake. The new Dwyer mast came with a hinged step rather than a tabernackle with one pivot bolt. Here is a link to a diagram of the step. It doesn't appear to allow for pivoting once you lift the mast and have the two pins in the base. https://www.dwyermast.com/images/dh2110h_linedrawing.jpg

To answer the part of your question not already addressed, you do not flex the mast to achieve the rake. Loosen the fore stay and tighten the back stay until the desired rake is set.Mark Dvorscak On Fri, May 3, 2019, 10:35 Gerry Lempicki via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
Now that the bottom paint project is near an end, I am hoping to start fitting my new mast next week. What is the consensus regarding rake on the 17? I see on Jerry's site that the M15 likes a little rake aft. Same on the M17 or no? And if so, how much is a little? Does one actually flex the mast doing this? The reason I ask is that the new mast from Dwyer came with a new hinged step rather than a tabernackle, so there is no pivoting on a tabernackle bolt once it's mounted with this hinged step and pinned in place.
