Thank you so much for this post!!!
I have been planning to make this same mod to my 2001 26X. I also have a BF 2.3 that I use for my dinghy but it's the short shaft model. By looking at your photos, I think I can make my motor work as well. I'll have to be a little creative and lowering things by 5 inches though. Very helpful post!

By the way, I've been lurking around on this site for years. All the helpful and informative posts on this site convinced me to take the plunge and buy our 26X back in 2014. I figured it was about time to chime in on the conversation.

Cheers,
=Bob

Hi Bob, welcome back.

The short-shaft model is probably doable with careful planning. My Panther mounting bracket has a travel of 14", but there are some slightly larger ones that have 16" of travel. That will get 2" of the 5 back, and then there is space inside the hull to mount the bracket lower. Next time I'm on the boat I'll see if I can get a guesstimate of how much lower I could have mounted it.

I suppose the last ditch to get the short shaft properly installed would be some manual modification to the mounting bracket. Like with a sawsall o a jigsaw. The Honda is likely light enough that the bracket could be cut down but still take the weight and HP of the little 2.3.

Old thread but very interesting to me (and many other threads about an auxiliary motor are now dead-ends)

I'm wondering what's the biggest engine I can stick in such a place?

My old 23ft motorboat has a 15 hp Yamaha 2-S that can push it along at a fair pace in good weather. I find myself reluctant to go through the process of installing a kicker, just for a few horses. I'm thinking more like 5 or 8hp as a minimum with the fast tides around here. As a guide, our low and high tides vary about 4 meters (over 12 ft).

In another thread someone mentions mounting between the engine and rudder? But all the older threads, the pix are now dead.

That little Honda is not available locally anyway. I'm thinking of a Mercury or Tohatsu 5hp standard shaft (available here). Doable with the same setup?

I don't see any long-shafts available, and sadly Malaysia doesn't yet get the concept of "put an order in". If it's not in stock now then it never will be.

How about a 10 hp? Too heavy?

An update on the Honda 2.3. It'll consistently push the X at about 4mph in calm situations, but it's very, very hard to maneuver the boat to a dock with it. Without remote throttle controls, and reverse being a 180 rotation of the whole motor by hand, it's really an emergency option only.

It's taken a beating.. one submerging on an underinflated rubber dinghy, and long periods of inactivity and winter storage, meaning old gas sitting in the carb.

Still runs well though, although it didn't want to idle this spring until I added some carb cleaner additive and ran it for a while.

I recently bought a more "real" dinghy... not an Intex rubber dinghy, but the smallest Suzumar they make, with the soft floor. For $700 cdn, it's not a real ocean going dinghy, but will get us to shore and back with four on board.

My eldest son and I ran the dinghy and the Honda 2.3 together for the first time last week. We transferred it to and from the rear mount ON THE WATER! Flat water, but still. It was very, very hard to do the transfer, as we were both in the dinghy. Getting it back on the boat was even harder from the water, and we almost lost it. Better to have one on board and one in the dinghy. I can't imagine trying to transfer any larger motor.

Maneuvering Maneuvering dinghy with the 2.3 is worse than driving a Mac with all the boards up. Like a floating bleach bottle, zero steerage. It moved the dinghy, but I didn't get a speed reading. Next time.

With that explanation, I suppose the dinghy does not have an inflatable keel. That would make a difference; so would a bigger motor. :D

I have a 6hp Merc on my 9’ Achilles, about 50 lbs/22.6 kg. I have thought about using my Merc as a kicker, but the thought of transferring it between the Mac and the Achilles brings me back to reality.

Hi All!

Interesting topic here!

We’ve discussed getting a small outboard for our small dinghy to be used on our planned longer travels along the ICW … rowing it with two adults, a dog and knapsacks really is a non-starter… especially if there’s a bit of wind & wave action … sending the Admiral ashore to walk the dog by oar isn’t even a topic of discussion..

We’ve unfortunately seen episodes of ‘let’s try and drown ourselves’ :D :D play out in the relatively safe environs of a marina where individuals were either transferring their dinghy motor off-of or on-to their boat. It’s been even more entertaining to watch the process of getting the motor on or off the dinghy while afloat. The manhandle aspect of something weighing 30-to-40 lbs at generally arms length while dealing with waves, wakes and currents has been truly cringe worthy to watch. Add to the mix that this process isn’t a common task or at a familiar location only adds to the distress.

Doubt that we could do any better given our age and physical issues attempting to do it the same way. :D :D :D

But there is a two part alternative to be had I believe that would accomplish the desire to use a dinghy motor as a reserve kicker for the boat and to get it on/of a dinghy.
I’m one of those that likes to do things single-handed if possible but try to use brains instead of using up my limited brawn or getting hurt.
The use of a small Davit Crane with an appropriate stabilizing line along with a cinching block and tackle I believe would be of immense help with this process. To that end I’ve been working up a design that would work for our Mac26X.

The the first part is a sliding kicker engine mount to raise/lower the kicker in/out of the water while on the starboard stern of our Mac26X.
This is a two piece captured slide (so the darn thing doesn’t visit Davey Jones Locker) that we would use an appropriate lanyard to pull up and lower the engine with. A keeper pin would hold the slide in the desired up/down location. A telescoping link arm with a pin would connect to the starboard rudder to effect steering from the console. Throttle would be via an extension handle similar to what is used on small johnboats and runabouts to allow the operator to sit more forward. Shifting from neutral to forward or reverse is still something I’m working out as it’s dependent upon the actual kicker motor. Rip cord starting is also a challenge but it could be accomplished at an intermediate location along the slide length where the lower unit water inlets are submerged but the power head is higher up and has better access from the stern well area.

The second part is the Davit Crane which is collapsible to store vertically along the corner of the aft starboard stern to be out of the way when not in use. When in use the arm is raised and the telescoping diagonal is pinned in the desired position. The location allows or the davit crane to pivot about 270 degrees to facilitate lifting the kicker motor from the slide plate and can also allow for the safe stable movement of the kicker over to the dock (when the dock is over on the starboard side of course :D :D) if desired or dinghy. The end of the davit arm would have an appropriate eye to clip a self cinching block and tackle to safely hoist/lower/keep the kicker at the appropriate height desired. Similarly the kicker would have to have a central top lift point to clip on to. The block & tackle line length to a stop knot would be such as to preclude ever dropping the kicker powerhead into the water (based upon calm water conditions as a baseline). The line would continue past the stop knot to allow for ease and safety of handling. Secondary “tag line(s)” would be available for used if/when needed to help control possible pendulum swing to some extent. One hand to the block & tackle line and one hand to the tag line(s) until where desired. Then cinch the block & tackle line and guide the kicker into place and secure.

It’s not as complicated as it sounds but would require some coordination and practice.
While still just a ‘paper chase’ at the moment it’s something we’ll continue to work on time permitting.

Our minds aren’t fully made up as yet on a gasolinekicker/dinghy motor as yet.
The alternative is an adaptation of a trolling motor like Minkota offers with a mount on the boat and a second mount for the dinghy.
The advantage is console/remote control while mounted on the boat and quiet slow trolling/station keeping while fishing.
The transfer to the dinghy mount is relatively light weight and snap in simplicity. The dinghy mount would be a simple manual (over-ride) control. The battery would be the heavy object to contend with but should be manageable with some thought.

Just ideas… maybe someone can also see a use for them and have a safer and happier time than those we observed earlier in the marina manhandling the kicker on/off.

Best Regards,
Over Easy😎😎🐩🐈

A challenge you don’t mention is how to stabilize the dinghy while manipulating a motor onto it.

Staying on your knees is essential. Trying to stand so as to get better leverage only makes for entertainment for anyone watching.

As to your invention; too much work. Trying to figure out on paper (old school) how to create such a device is a great way to pass time on rainy days; actually using the contraption, too much work. :D

I have a lovely Tohatsu 15hp outboard and a dinghy...

I'm thinking that rather than trying to get it onto the Mac, which doesn't currently have a mount for it anyway... why not leave it on the dinghy? That way if the main engine fails I can tow the boat home or to safety via the dinghy, rather than trying to manhandle the engine off the dinghy and onto the Mac?

What I don't have is a good dinghy with a hard hull, only an inflatable thing with floor boards that... sort of flex? I'm thinking of supergluing some rods or something to make the thing stiffer, cos it bends like a banana in the waves and wastes the engine's power. I doubt I'll ever try mounting it on the Mac, so thinking of just towing behind.

Anything in particular I should know about towing a dinghy behind? Am noob :)

Well...for one, they fill with water in wavy conditions so make sure the self-draining valves work and are opened. Two, they can actually flip in winds and waves, which is why with our soft-floor super-light 2.4m dinghy and 38lb motor, we're planning to keep the motor on the big boat. Three..it's important to consider how far behind the boat to tow the dinghy: if it's on the up-hill of the wake it can cause a lot of drag. Four...Docking while towing a dinghy sucks...watch the line in the prop, can't steer, etc. you can get a floating line to tow but I'm not convinced that'll keep the line out of the prop.

We did a lot of paddleboard towing last summer, and I had to assign a kid to handle the towing lines every time we docked or departed.

While I'm off reading that thread, what do we think of the "Sundolphin" rigid boat?

Dunno if you can see this link:

https://shopee.com.my/Sundolphin-Water- ... 7440626724

They say cannot ship to East Malaysia/Borneo but maybe can... As I recall, I saw on Youtube these things don't sink?

I do really like the idea of a separate, spare engine. Always had one on my motorboat, a little Yamaha 15, which we did have to use a couple of times. This time around I'm buying a brand new Yamaha 85 engine, so should be reliable, but it's a carbed 2-stroke, so by definition not that reliable...

Thing is, there just doesn't seem room anywhere to fit a kicker engine on the Mac's stern, as the rudders take up the space either side of the main outboard. As others have mentioned, trying to manhandle an engine, even a small one, while on the water is somewhat comical.

(1st) I could not open the link, but I saw it said “Sun Dolphin”; is this it? https://sundolphin.com/water-tender/

(2nd) You said your inflatable bends in the waves. Is it at the propper inflation. When my Achilles is inflated, it is quite stif.

(3rd) Many :macx: owners have successfully attached kickers on the stern, there is room. :macm: owners are the ones who have a challenge attaching a kicker.

Yes, that's the one!

Disappointed to see it is only rated for a 3HP outboard.

I do think my dinghy wasn't as inflated as it should be the first time (some mixup with the pump instructions, I forget now). So the 2nd time we made sure it was definitely super hard and pumped - and it was still pretty wobbly and bendy.

We found if my friend sat right on the bow it was much better, for some reason. I'm the guy with the red shirt:

When I have my wife sit on the bow of the Achilles, the dinghy will level off and plane more quickly.

With the 6HP Merc, we can get up on plane, but it is a bumpy ride.

Opened the link, only one person, and no red shirt. I suppose you’re Adam Karr?

Actually Alan Carr, that's my super-sneaky disguise name on Vimeo :)

My friend Simon is the guy in the green shirt, I'm in the red motocross jersey, piloting the bendy thing.

My current plan is to epoxy some 2" PVC pipe sections to the dinghy floor, then insert some 3/4" pipes inside, so it will be a bit more rigid but can still be collapsed if need be. Sounds planny?

Updated the earlier link as it was to my user page, should be this video here:
