Thanks, mine ships today I opted for the honda so don't keep the old one as a spare, and for
8hp over 9.9hp because of the lower RPMs.
How do you break in an outboard on a sailboat?

8hp over 9.9hp because of the lower RPMs.
I may be missing something in your question but shouldn't you just follow the directions from Honda as in post #10 above?
Seems pretty straight forward and suggests only very limited WOT periods.
Mom's AMC Ambassador was rated at 90 mph tops but she got 110-120mph out of it. It was probably
because you don't get carbon build-up when you run it wot.
The question was if I can do that on the Mac without spinning the RPMs. Maybe you’re a bad influence on me I end up ordering the 8hp rather than the 9.9hp because the RPMs are 5000 wot rather than the 6000 on the 9.9hp, and since it’s the same engine otherwise it may make for a better and longer life.
Personally I’m having some trouble understanding what you are saying.
This is an example. “Spinning” is “RPM” and even then doesn’t have much to do with what boat the motor is mounted on??????
If I may provide you with a basis for understanding. It started with a question, not an answer. If I mounded this engine on an aircraft carrier you would have nothing but spin so now it has everything to do with the boat. The lower RPMs and lower HP, in this case, it is similar to avoiding tire spin. Slow it down to improve performance.Personally I’m having some trouble understanding what you are saying.

Its all moot. A 26c will only plane on the trailer, and the Honda wont have anything to do with that!
I love my 26s and love that she can camp at Walmart and on the lake and I love that she has no mods. I'm told that she's fast but it will take years for me to find out.
Thank you all for taking the time to help me. I'll have more questions such as should I also take my old 80/90 Nissan 8hp 2 stroke (the blue one) with me on outings and where to keep it on the Mac26s

we used to do that in ours, way back when, but never in Waldorfmart. This year was the plan in the 270, but we all know how that thought ended.
Here is the circumstance that led to my ordering the Honda 8hp which will be here on the 21st. Looking forward to a magical Christmas and a long wait for spring. Let's Go Sailing Season 2 Part 2 - YouTube
Never heard of break -in procedures that required running the engine at full throttle for hours on end. On the contrary most require that you avoid running at full throttle other than short bursts. I have also never heard that the break-in procedure has to be completed in one day. I would operate the engine at idle or low throttle until it warms up to operating temperature and then run at mid range RPMs for the first few hours. In the next outing I would again warm up the engine and then run at a higher range of RPM and introduce short bursts of throttle to WOT and back. During this phase the idea is to avoid a constant speed and introduce speed changes at different time intervals. I would avoid running at full throttle until the break -in period is complete and a change of oil is done. I do not like the idea of using a trash can as the loads in a can will vary considerably with those imparted by the boat in the water. It is best to subject the engine to the loads as it is intended to be used for the parts to start wearing down evenly in line with the normal loads it will experience in its useful life. I have always broken -in engines during my normal course of using the boat. I doubt very much I would ever do it in one day, but if it takes a week or even a month I would be OK. have had engines that lasted a long time and other somewhat less but have never attributed a break down to a bad break-in.
Yes it is. We bought a new Suzuki 2.5 for the dink last year, ran it for an hour in the bucket, and then followed the instructions in the manual, changing the oil and leg oil as requested. Not that difficult and not something that requires all kinds of input from the ol interweb. Read the manual, and follow it.

I think what the orignial question was how fast to go with others on board. First you own the boat, Second use your head and follow the break in for the engine. Third, disregard what others tell you as you own the boat, not them as you are the owner and skipper. take charge and be safe having a good time
Well, that certainly answers the question about who owns the boat, Dave. But to refresh everyone's memory, here is the original question: "How do you break in an outboard on a Mac26s if you do not want to go beyond hull speed given that they want me to run wide open for hours and hours (all day)? "
The general consensus has been that the poster has misunderstood the break in procedure stated in the owner's manual. Pretty much that simple.
