Yamaha T9.9 question

My sailboat's transom is raked at a 56 degree angle, and the Yamaha T9.9 doesn't have enough adjustment to compensate for that rake. So I am making a wedge to put between the transom and my new Garelick heavy duty bracket.

Unfortunately, my motor is in FL and I am in NY, so I can't just go look at it.

My question: Can the T9.9 be mounted on a bracket that is completely vertical, i.e., at a 90 degree angle to the water?

The reason I'm asking is that the shop manual shows the bracket at a 12 degree angle from the vertical.

There are 4 holes that allow the angle of the motor to be adjusted by about 4 degrees for each hole.

I can't figure out, by looking at the diagram, if the bracket has to be at least 12 degrees from vertical, or if that is the maximum angle of rake that can be compensated for.

Can anyone shed some light on this question for me? I'm sure it's obvious to anyone who has done this before.

Thanks: John

Well, after doing a lot more reading, I think the answer is that outboards are built for transoms built at a 'standard' angle of 12 degrees... i.e., 12 degrees from vertical.

My transom is 34 degrees from vertical (56 degrees from horizontal), so I guess I need a 22 degree wedge. That should put the bracket at the desired 12 degree angle.

If anyone can confirm I have this right, I'd appreciate the sanity check.

Lightbulb Vertical = yup

Our previous boat for a decade was a Niagara 26, and the transom was approx 90 degrees to the water since it had a transom-mounted rudder. The motor was in a cut out on port side. I had a Yamaha 10 (25 inch leg) High Thrust with the 3 to 1 final drive gear. Awesome engine for a sailboat.

So my guess is that vertical is just fine. Of course I was not stuck/cursed with a bracket mount, either. Thank goodness.

best,
L

ps: I did indeed check your blog. Nicely Done!

Well, you threw me into doubt, so I decided the best idea was to drive down to my local Yamaha dealer and put eyeballs on the product.

It turns out you are correct. All the display engines were mounted on vertical mounts, so mounting on a vertical transom (or bracket) is no problem. In fact, that's what the service manager recommended, so that's what I'm going to do.
