Repowering 13' with Honda 40

Hello again Whaler gurus,
It's been along time since I've posted here, but need to tap into some of the experience that lurks here.
I'm real close to buying a used Honda 40 from a reputable source near by for my 73 13'er (20" transom) for the sum of $3600. The engine is immaculate and before I buy it I will have a mechanic check it out.
I did some searches on the site, and I understand there are issues with adding this much weight to the transom. I routinely tow the 13 long distances in the open ocean behind a sailboat, and the current motor (75 evinrude 40) does not cause me problems.
Does anyone on this site actually have a Honda 40 on a 13 and how real is the concern about shipping water over the transom?
I think I really want the 40 because I want to maintain the option of being able to ski behind the boat, but I don't want to swamp it while towing it 50 miles off shore either.
I would really like to hear from anyone who has a Honda 40 on their 13 and what their experience is.

How much did the Evinrude 40 weigh? The Honda 40 is 198 lbs.

The 40 is just too much engine and weight for a 13 that is to be towed or which is to be used as a tender. Get a smaller engine, and if you need a ski boat get another boat.

Interesting: Honda 40/50 (from website) weighs 198 lbs!
New Johnson 40/50 (2 stroke) weighs 195 lbs!
Merc 40 (2 stroke) weighs 204!
Merc 40 (4 stroke) weighs 216!
Choose your weapon....

I may be wrong, but I think the 75 Evinrude weighs 130 lbs., 86 lbs. less than the four stroke Mercury. 86 more pounds on the far aft end of a 13' hull may not be optimum for a towed tender.

I believe the current engine is spec'd at 155 pounds (I'll check tonight) I always leave port with a full 8 gallon fuel tank which weighs about 55 pounds and sits touching the transom.
I suspect if I kept the tank on board the big boat for travel, I would expect pretty similar towing performance with the honda 40 or 50 that I do with the current motor and a full tank of fuel.
I was really hoping somebody here actually has a honda 40 on a 13 footer. I'm surprised nobody does.

1971 Evinrude shows the 40hp(old spacecraft style) at 132 manual & 140 elec. Don't know if the 1975 was the same engine.

I went through that link before I started this thread. (I tried to do my homework!) It seemed focused on the earlier hull, short transom. I did follow the link in it to the pictures area of the 40 merc on a 13. I can definitely notice the difference in static trim between that boat and mine. It looks like 2-3" lower in the stern. On my boat the water just laps on the edge of the sides.
The '75 40 weighs in at 135 or 140. I looked at the service manual this morning, but I already forgot the exact number. I guess I would be adding 60 pounds in the stern if I go with the Honda 40.
Thanks to all for the input

I had a 200-pound 40 hp Johnson on my 1972 13' and the weight was no problem. Do not use a jackplate, though, and put a low-profile 12 -gallon Tempo tank under the forward thwart.
