How much motor does a 12' fg need?

I don't know if licensing is related to horsepower here, but there's one
lake where there's a 10 hp limit. My dealer has repeatedly offered to
get me a different decal for my motor, since (according to him), the
only diff between the 10 and the 15 hp motors is the carb.


My 14' boat with 15 hp was automatically covered under my State Farm home
owners policy. My check on the HP limits for coverage.


You might want to double check that insurance. I also assumed that my
homeowners insurance with State Farm covered boats up to 14ft and under 25
hp. as it stated. However, my agent told me that was just for loss or
liability if it was operated on waters totally within my property. Or was
stolen or damaged by wind/fire/etc. He said that as soon as I pull away
from my dock on the river, the coverage ceases and that I would need
liability coverage to protect from any injury or damage that I might cause
to anyone else. Liability on a boat is pretty cheap. I pay about $70 a
year to cover my 24 ft pontoon boat..well, maybe not so cheap since I only
managed about two weeks in the water this year due to flood waters. I've
been back in this area 5 years, now and this is the second Summer that the
Sheriff has closed the river to boating due to high waters. 50 years ago,
when I was a kid in this same house, nobody ever thought of closing the
river...we just all had the common sense to stay off when water levels
were dangerous. But then, there weren't any million dollar houses with
expensive boats and docks to be damaged by boat waves, either.

My policy covered me liability wise with the 14' boat. Was in the small
print. My 21' boat costs me $240 a year for $20k boat and trailer.

What do you want to do with it?

If speed is a high priority, go for the larger motor.

Be aware that if this is an older boat, that 14HP designation was
likely made with a 2-stroke in mind. Four stroke engines are heavier,
so from a weight standpoint you may want to back off on the max HP if
you're gong to use a four stroke.

You can move the boat with a very small outboard, beyond that it's a
question of how important you think speed will be.


Thanks, that's useful info. Speed is not a big deal, but I do want to
get it planing efficiently. I hadn't thought about the weight issue,
it is 25 yr old or so Sears fiberglass 12' boat. Sounds like the 9.9
hp would be OK, and I know some lakes around here limit boats to under
10 hp.

I think top speed is about the same but I'm able to run faster than
before because of improved trim, less bounce and better control.

I don't really track fuel economy on the dinghy but consumption seems
to be inline with what I'd expect for a 20 hp motor. I probably
average about 1.5 gph unless I'm really running it hard.

Minimum planing speed has improved a great deal but even more
importantly, the transition between planing and not planing has
smoothed out, allowing much better control of speed in that range.

I've got a 14' aluminum yacht rated for 25 hp, but my motor's 15 hp. I
can hit 22 mph on flat water with two adults on board. The boat itself
weighs about 400 lbs. Check your boat's weight and that should give you
a useful guideline.

Also consider who will be in the boat much of the time. I often fish
alone, and my motor's a tiller model. So, I'm in the stern along with
the battery. That raises the bow (affecting visibility) under certain
conditions and no amount of motor angle adjustment helps. I usually put
a couple of 50 lb sandbags in the bow. Even so, this nixed the idea of
upgrading to 25 hp a few years back. That, and the fact that flat water
almost never happens around here.

A while back here, people would buy a 9.9 hp outboards to avoid the need
to license their boat.
I have a 25 hp on a 14' 6" aluminum boat now and found the licensing
procedure to be free and relatively painless.


I don't know if licensing is related to horsepower here, but there's one
lake where there's a 10 hp limit. My dealer has repeatedly offered to get
me a different decal for my motor, since (according to him), the only
diff between the 10 and the 15 hp motors is the carb.

Also, here in N. Il. the reason for the 9.9 was to be legal on the smaller
lakes that restricted horsepower to under 10hp. Even canoes and rowboats
have to be licensed. Our local state park/lake has no restrictions on hp,
now, but restricts all boats to "no wake".

Here, the limit on this particular lake is for reasons of cleanliness, at
least in theory. It's the water supply for the city of Rochester. In
reality, you can have a legal size motor that creates an oil slick as soon
as it hits the water, but a larger motor that's spotless is illegal.

Nobody knows how to deal with this irony, so the law stands.

My homeowners policy would cover a trailerable boat up to $2.5K
I pay for a rider to cover the actual value of my boat.

Thanks, I just may give it a go.
One other sort of off the wall question. Do you use muffs to flush
your engine? Something unique to this 20hp Honda, I've found that my
engine eats impellers for breakfast when I regularly flush it on a
garden hose with muffs. I've lately started running it only in a
barrell and so far -fingers crossed- so good. I've owned a lot of
outboards but this is the first one that's acted like this.
Anyhow, I was just wondering.

As for the original question, I agree with Wayne. I can't think of an
outboard at 14hp or 13, 12, or 11 for that matter. I think 9.9 hp is
the most you'll find without exceeding the hp recomendation. You'll
have lots of choices at 9.9 and, with the right prop, that should push
a 12 footer along smartly. On the other hand, it depends on what you
want to do with it. A 5 or 6hp will shove it along well too, but just
not as fast. Maybe you can borrow a motor from someone just to get an
idea what you want.


Thanks for the info. I wasn't sure how much power was needed to get a
12' boat planing. I'm pretty good at searching the internet, but
couldn't find any guidelines on outboard hp selection.

If 6 hp will get it moving, and 15 hp is beyond the boat's rating, 9.9
hp sounds like a good choice.

I would skip the single cylinder models and get the 8HP or 9.9HP. They
are much smoother motors.


Thanks, that's the kind of info I need. These tips will save me from
learning the hard way.

There is a port built into my BF-20 where you can flush it without
running the engine. Honda sells a small screw in adapter for a garden
house that costs about $15 if my memory is correct. It's a lot
cheaper and easier than replacing impellers.

It should go pretty well with a 9.9 if you don't load it down too
much. I'd recommend a Doel-fin if it is slow to get on plane. I've
become a believer since I got mine.
