I figured it out - just made something out of 1.5 starboard. The key was recessing the place where the outboard mounting flanges connect to the board so it can't slide off. https://lh3.googleusercontent.com/uL3Nh_iisskqJtpkyk_PWQoz9_Sq1_1kojDJUxrnF781rKTQNIlblalDVRo3ra-KvKRALgC_GpyMVf0H8qih9O4Gm-wqq...

Hi there, I'm looking for a replacement "board" to connect to the aft side of the outboard mounting bracket on a MacGregor 25. My boat came with a wooden mounting board, but it's too slippery and the motor fell off sideways last week into the water when steering sharply. I realize I could ...

I don't think it is. You'd have to modify it.

If you posted a picture of your broken rudder I might have an idea how to fix it. Mine snapped in half and I fixed it.


.. or if you're up for a drive: https://chicago.craigslist.org/nwc/boa/ ... 04810.html

In my opinion the first boat is overpriced. The second is probably about right.

Just to post an update about two experiences with this rudder design. First, prior to reinforcing the top with the biaxial cloth I went sailing. When turning sharply on a run the bottom half of the rudder broke off entirely. I repaired it by drilling 7/8" holes deeply into the remaining portion...

Reading through some other forums and specs, and it looks like both the Chrysler 26 and the Ericson 25 have keels or centerboards with another 1000 lbs of lead in triangle-shaped cavities around the keel... which is exactly what I was thinking of adding to my Mac. That said, just buying one of those...

Thanks @The Cuscus. I could do that for sure, and it might help with adding tongue weight too.

@Others Any particular reason the Seaward is better than a Chrysler or a Balboa in heavy weather?

I'd assume they all suffer from the same risk of fiberglass breakage if the keel slaps back and forth.

Wow - yeah that would toast my price range. Seems not that different from a Balboa though.

Chrysler 26 looks pretty appealing -- heavier than a Balboa, and more headroom.

Thanks kurz. I think it should work now.

I have a Mac 25 which I love, trailer to fun destinations all the time, and have customized to fit my cruising needs. The only thing I don't love is the poor comfort ratio, tenderness, leeward slippage, and my fear of getting knocked down in a surprise squall on Lake Michigan. I'd like to add some b...

Here are some photos of my rudder mod. Went for a NACA 12 shape. The last photo shows how I'm reinforcing it with biaxial cloth on the weakest point (where the wide part connects to the narrow part). Highly recommend hooking a shop vac up to your sander :) https://lh3.googleusercontent.com/d5-Ww83bK...

Speaking splashing, has anyone found a good solution to prevent water from splashing into the boat from the area near the keel when heeled with a heavy crew?

Does anyone have an old broken tiller pilot where the motor won't move the shaft anymore, but the electronics still work?

If so, I'd like to buy it off you to do some futzing.

Maybe something like this:
