Good to hear that there was a satisfactory solution to the engine mount problem. Please post a photo after the new hardware is installed. Happy Thanksgiving to y’all too.

If you have a horizontal windlass with a gypsy on one side and a drum on the other you can use the drum to hoist the dink (we also use it to take us aloft quickly and easily) on the spin halyard. This really makes that job much easier.Hi again, guys! Mrs. Pumpkin Pie here. Thank you to everyone who has given feedback for us to take into consideration.After great deliberation, we have decided to mount the engine elsewhere. Sure, we could have beefed-up the seating and supports, but we didn't feel that would totally eliminate the issue at hand with our particular boat.
We have waited a few weeks for a fabricator/welder to come out and fab relocating the engine mount to starboard side. The guy went AWOL and never showed up after empty promises.
His idea was to mount the 15hp engine on the starboard side coming off of the 2" pipe on the arch with a 1" stainless steel pipe and making a T for the engine mount bracket to be placed on. He said once completed, the engine would not budge. I'd love to hear anyone's feedback about mounting the engine coming off the arch.
On another note, for anyone that has followed our dinghy dilemma, we had a rigger come out to install our spinnaker halyard which enables us to lift our dink up and on/off the bow of the boat with ease.
We hope everyone has a happy Thanksgiving and safe travels!
Way off the subject...
Other than proper English, what difference does it really make? You can’t eat the title.
Same in CA. The interesting thing in New South Wales (AU) is that registration of a motorized dink (any motorized boat) is required only for those with 5 hp and greater engines. So when I flew there in ‘03 I took my aero inflatable and my 4 hp 2-stroke Evinrude. You can take the Evinrude apart for packing in a footlocker. So, I needed no registration of my (foreign) water craft to use it there
. Very sensible law as it excuses many actual yacht tenders from registration. Something once true in some US states if the yacht was USCG documented. Also, there are many mechanics in NSW (Sydney area) who know much about the Johnson/Evinrude product line.

So, last year I bought a 9.5-ft AL RIB that weighs about 125#, and for reasons too complex and likely too boring in their entirety to explain, I bought a 4-stroke Honda 8 hp (15 in shaft), deciding on it rather than the Honda 9.9 hp of the same weight—about 92#—to power it. The 8 hp was maybe $300 less, but that was not the deciding factor. I was assured that the 8 hp was sufficient to plane the RIB with Admiral and me aboard and that the only difference I would notice was the top-end speed, the 8 hp being limited to about 15 kt whereas the 9.9 hp could-would make 20, etc. Of course, this is a salesman I’m talking to who, for all I know, had never been in a dink that size with his wife and a heavy 8 hp outboard trying to plane the boat.
The short of it is, is that the Honda 8 hp cannot plane the boat with the both of us aboard. It will, however, reach the promised 15 kt on plane with me alone. Yes, I’ve monkeyed with the trim/tilt settings. NG. My first thought was that, man, I need to get back on the ole diet!!
This on-going, tormenting miscalculation drove me to buy, on a “whim“, a 9.9-hp 2-stroke Evinrude from the shop where the 5-hp Tohatsu was being serviced, rather than attempt to trade up/in to the Honda 9.9-hp 4-stroke (no worse of a corrective transaction for $$ originally misspent; maybe a better one). About 2 weeks ago. When we first took off, even the Evinrude 9.9 hp could not get the boat up with both of us aboard. But after adjusting the trim/tilt we finally got going on the plane making about 11-12 kt SOG sustained. With me alone aboard, the Evinrude makes only what the Honda does, about 15 kt SOG. Interesting. The difference in the weight of the motors is only about 14# or so, the Evinrude the lighter.
Where am I going with this? To the PPs. Just be aware that your new combination of boat and motor may, or may not, perform as you expect in the conditions you expect just b/c the published “numbers” say that it should. Better try it out if you have not. People, gear, pets, supplies—whatever. You mentioned SCUBA gear earlier. Very heavy stuff. Be advised, I compared these engine’s performances on an erstwhile Olympic water-ski stadium in Long Beach. (Flat, smooth, protected water.) I was astonished that the lighter Evinrude at 9.9 hp could lift and plane the boat but not make any higher top-end speed than the heavier Honda 8 hp. Something still seems amiss. Working all of this boating stuff to best outcome with the fewest “gotchas” is truly an empirical art-form.

Have you tried one of the bolt on Hydrofoil trim tabs. I have one on the 15hp and makes a huge difference popping the boat onto plane.
No. But I’ve considered it, and may yet try them. The Honda is already unruly to move about, etc. Yet one more operation to attend to to maintain and stow/store the outboard.

Once you're up on plane, prop pitch and RPM are the key factors determining top speed.
If you're willing to sacrifice top speed your 8HP might get you and your wife on plane if you swap out the original prop to a lower pitch prop.
