Twin,
the side by side twin step Fountains came with them spinning out.

On my 32 I tried them out. In the mid range it wanted to make the boat hop more, even the wife noticed.

No real top end difference, maybe 1.5 slower.

Put them back to spinning in and just trim out when docking, no problems.

Brad,

if you rode in my boat and see how hard it can turn you will see spinning in doesn’t bother it, in fact you may also wonder about all the stories of how steps make the boats spin out.

I have suprised more then a few people. Just got to know what not to do.

Wildman,

That's why my post was speculative. I have zero experience with twins at all. I'm just looking at the physics of it. I might also wonder if the length of your boat contributes to its stability, in spite of the props spinning the way you have them set up, where the OP doesn't enjoy that luxury.

I am genuinely curious as to the findings.

Thanks. Brad.

Did some testing yesterday.

And it is/was, proof of why we test.
Read everything but, test!

Boat still rolls to starboard coming on plane, maybe less aggressively, then the starboard wheel breaks loose and spins!

I also added a 1/2” of positive toe to the motors.

Had a fuel supply issue and was only able to do very short runs.

Have material to extend my tabs and will try again.

Gary are you spinning out now?

In

Was out.

Didnt get over 20 mph due to fuel supply issues but was better to that point.

I see. Thought you were in and going out. I would have thought out would be better with your setup...but like you said test...,,

I’m wondering now……

I was quite restricted w/tab mounting locations due to the bracket design so I’m wondering if the exaggerated down angles are deflecting water flow to the props??

If so, this would change w/speed and explain the issues I’m seeing.
Theory is that extending their length will reduce that effect.

Tempted to try the previously suggested go pro mounted to watch this but as I’m testing solo, I end up trying 2 or 3 things at once to reduce my trips.

We shall see……

Gary,

I Have always found it more productive to test one thing at a time, to avoid any intersectional effects. Don't, say, swap props AND rotation direction for the same test session. If you want to test an electrical fix or improvement on the same test session as a prop swap, that would probably not cross contaminate, but a rotation direction swap and longer tabs very likely would. Just my two cents.

Thanks. Brad.

Decided to get after the cosmetics.

Thought the gel on the deck was beyond saving and had planned to paint it.

At this point, not willing to dedicate myself to that level though.
W/everything else on my plate for this project…

Started w/a buffer and rubbing compound and although it was helping, the gel was so porous it was absorbing the compound before I could hit it w/the buffer.

The bow railings were loose and water was leaking into the cabin and getting to the balsa so I removed them to repair that and thought….., it’s now or never for the deck!

Pulled the rest of the deck hardware.

Used a (2nd) pc of crap, Harbor Freight pneumatic orbital sander and experimented w/1500 wet/dry, then to rubbing compound, polishing compound etc, etc.

Was amazed at how well it was coming out so said fk it and dove in head first!

This is after 10 hrs of work.
2nd pc of crap sander lasted 3 hrs!

Very happy w/results!

Not bad for a 37 yr old boat, built in Ohio!
