Thank you Pro10is for such a comprehensive report. I completed the shakedown cruise on my rig yesterday and it exceeded my expectations.
I bought the Suzuki for its weight and also it was on special from my local dealer.
It is not easy to source Yakattack here in Australia and when you can, it is expensive so I made my own backing plates from 316 Stainless bar that I had drilled and tapped.
rather than Aluminium, I used more 316 Stainless angle for the cross brace and a piece of hardwood flooring joist to actually mount the motor, which is attached to the angle with 316 stainless coach screws. This way I avoid the electrolytic issues of mixing aluminium and stainless steel around salt water.

It is all constructed to the dimensions in the primary post and it worked a treat. As soon as I work out how to post images and video to this forum I will add more detail.

After a year+ considering this, I'm finally going to add an outboard.

I'm going to get the Suzuki 2.5. But is there a consensus on the Short or Long Shaft version?

After lurking, researching and talking about this for far to long, I finally took the plunge and did the outboard mod. It has been fun to see over the last couple of years how the mounts have evolved. I didn't do a whole lot to advance this design. It's simple, solid and can be built with basic tools. You could literally build this with a hand held drive and a hack saw. That said, a few other tools make it cleaner and easier. I used just under 36" of 2"x1/4" walled square tubing and 12" of 1.25x1/8" walled square tubing. To cut the aluminum, I did something a bit different. I bought a non-ferrous metal cutting blade from Amazon for my miter saw and a speed control from Harbor Freight to slow the saw motor down. It was an inexpensive great combination for cleaning and easily cutting the Aluminum.

I do have some thoughts on an improvement in the design. The improvement makes the build more complicated but allows for greater adjustment of the system.

What really amazed me was just how solid the whole mount to boat turned out to be.

I'm happy to answer any questions on the build. Maiden voyage is a week away!

Great job! One of the cleanest and best engine mounts yet. It looks like you incorporated all the upgrades and made a few of your own.

Let us know how it works.

Thank you, pro10is! It was really all of your ground breaking work and insight that inspired me and gave me the confidence to take on this project. I'm at a stage in my life with kids and a demanding job where I just don't have the time to experiment and work a lot out by trial and error (I'm lucky to even get on my TI a dozen times a year).

I'm thankful for everyone who has done a lot of the work before me and shared their experiences online. I'll continue to share what I learn and the ideas for further enhancements.

@atv223 - did you get the 12" or 16" YakAttack mounts? I got the 12" but it looks like you have the 16"? I may exchange them before I do the install if so.

Thanks!

Mine are 12" and are plenty long.

Great job! Looks solid... the question I have... how has is worked over the past months... and would you make any changes to the build if you had to do it again...?
Thanks, Steve

Well done!

Enjoy your new motor mount on your Island.

The design looks identical to the one i built. See below.

I can report that after several hundred hours of use the design is very robust, strong and well suited to off-shore challenges.

Have fun!

Well, it's been a couple of years since I updated this thread, time flies.

Back in 2018, I got tired of only going around 3-12 knots on my TI and felt the need for speed, so I purchased a new 300HP SeaDoo GTX PWC that can easily reach 70mph in seconds. Overkill? Yep, but it was fun, and you only live once so no regrets. This was, and still is, awesome. And it has a range of around 70+ miles so I got to see areas where I boat that I could never reach in a day with my TI.

That said, after a while, I really missed my TI. I was going to sell it, but I just couldn't bring myself to do it. I'm glad I didn't because this year I plan to use it a lot. The SeaDoo is great when I feel like boating fast and furious for hours, but at my age, that can be a bit tiring. When I want a peaceful, relaxing day on the water, the TI simply cannot be beat.

So this year, I finally ordered the Suzuki 2.5hp outboard for the TI. This will get me to my favorite boating areas as quickly as possible where I can then sail when the wind is right, or use my Torqeedo 401 to cruise around in relative silence. Nothing is better than a wonderful, relaxing day on the water with the TI.

For the purposes of this thread, I'll report back on my experience using the Suzuki. I had no luck at all with the Tohatsu outboard, as documented here, but the Suzuki should be far more reliable based upon the experiences of others.

I see you've posted a photo of a rear-mounted Torqueedo 403 on a Hobie TI; how did you mount it so the rudder can travel up and down?

The 403 is mounted in the back of the rudder as shown so it can go up and down nearly as normal. If the rudder is raised in a straight position, it cannot go up all the way, but it'll be entirely out of the water. If you simply turn the rudder to the left or right before you raise it, it can be raised all the way as normal.

This ends up being no issue at all.
