18' Bayrunnner on 15 hp Outboard
 

I picked up a used 18' Bayrunner (aluminum boat) from a kind lady that
her husband owned. He passed away. He placed a 15 hp outboard and
from the size of the boat it seems a bit small.

His son told me that with him and his dad they can cruise at 15-20 mph
and cut through wind with no problem so his dad never thought about
placing a larger motor.

If I'm in choppy water (1'-2') would this motor be large enough for me
and a friend to ride in? It can get windy where I'm at. I'm not
looking for a speed boat but I don't want to be underpowered for safety
reasons.

Any experience would be appreciated.

I believe the motor would be powerful enough in 1 to 2' chop in an aluminum
boat of 18' LOA.. The question of sufficient power for two large adults can
best be answered by an on-water test. Get a friend and give er a try.

I thought about that too. Just concerned about being sucked in to the
middle of the bay from wind and chops!

It's actually rated for 75 hp but thought why go up if the motor has
enough power. Lower fuel cost and easier to work on it but I do take
underpowered issue seriously as it happend to me before (another
story).

Good question.

Personally, I would have a little trouble believing that 15 horse on a
18' aluminum boat with two people will do 20 mph. I have a 14 foot
Princecraft that, loaded with gear, me and one other, will do 20 and
it has a 25 horse Johnson.

If that is a GPS speed, then you have to take him at his word, but I
would be suspicious of it. When you are low to the water and moving
you have a different perspective - even at 10 mph, it might look twice
that fast give wind and wave action. For example, if I'm running my
Ranger center console flat out at 50 mph, it hardly feels like I'm
moving that fast - same on my Contender. But people sitting down in
the stern or console seats, it's quite different - they can "feel" the
speed.

Another issue is "choppy" water. 1 to 2' isn't choppy in a boat like
that - it's a fairly decent size sea for a small open boat.

In my opinion, and if the manufacturer allows for upping the
horsepower (like going to a 25), then I would. And you can get your
money out of the 15 - used small motors are a rather valuable
commodity.

I dunno, a 15 just sounds too small for an 18' unless you're running
bare (with minimal to no gear, etc.). Only way to know for sure with
your boat is to give it a trial run.

Given a 75 max rating, I'd think a 25 would be the _absolute_ minimum
with gear and maybe a 40 or 50 as a compromise between my minimum and
the max.


Though I have no idea how the weight compares, my grandpa had a 12'
Sorenson with a 15, and it was an absolute dog, just barely able to get
two people up on a plane running bare. In comparison, my great uncle had
a 13.5' Livingston with a Merc 50, and that was just about right. (Well,
maybe a *trifle* overkill...) :)

If fuel costs are a concern remember that, even with a larger motor, you
don't /have to/ run at full throttle all the time.

Listen bud don't let the speed deamons scare you. I have an 18ft lund
explorer and it's probably heavier than your bayrunner. it has a 25 and a
9.9 on it. The 25 runs that rig at about 30-35 mph depending on conditions
and the 9.9 will push it to around 20 it's because of the prop on the newer
engines that you get these results. Your 15 on that boat should do just
fine. It all depends on how fast you need to get where you are going that is
the real story here. The guy you bought from like me was probably a true
fisherman, and not someone who had to get to the other side of the lake
first. Relax and enjoy the 15.

That's what I heard from his wife and kid. I heard he's always
catching fishing and loved the waters. Hopefully, the current setup
will push me plus one atleast 15 mph. I'll know this weekend.

Planet earth Tom. I just came back from Greenwood lake and used the speedo I
ran 32mph across the lake. It's possible the Lund cuts water better once
it's up on plane than what you are used to. Sorry you don't agree.

You have a 18ft Lund Explorer that has a 25 hp engine and it will do
30/35 mph along with a 9.9 that will push it to 20 mph.

My friend had, up until this year, a 35 johnson from 1980, the same model
that is now a 25. It would do 24 mph wide open, by GPS. Perhaps yours
is a lot faster, or perhaps you need a new speedometer.

Guys, Guys. we are all in this together. First off my Lund is a 97 model and
is not as wide or as heavy as the newer ones. and it is only rated for a 40
tiller not the 150 you said.. I may possibly need a new speedo but not
because of this issue. I guess you guys that are questioning me are probably
made about my crack about being a real fisherman and not being interested in
speed just catch. Sorry if that bothered you it's just my opinion. And lets

I am not running a older OMC Johnson it's a newer Suzuki 25. it may sit in
the water just right with this motor, the pitch of the prop may be just
right, and possibly the lake was too calm when I ran the test, all I know is
it just ran great and better than I expected.I'm sorry you guys don't

I don't know about the rest, but I'm not mad. It is just that my
experience and my friend's experience contradicts your claims. Who am I
going to believe, you or my lying eyes? And my buddies 16 foot lund is a
1979 or 80 model. Another buddy has a Alumacraft "backtroller" with a
merc 50 and it goes in the low 30's.

So why should I believe you and not my lying eyes?

Like I said, I'll take you at your word.

But...

I have a 14 foot Princecraft Yukon with a 2005 Johnson carbed two
stroke with a non-standard prop. With me, 150 pounds of gear, a
transom mount transducer and stern mounted trolling motor, I can just
barely turn 25 mph. That's with a strong tail wind.

So there you go.






There's also the fact that speedometers tend to be inaccurate.
Check your speed with a GPS unit and you will probably find that
it's not quite 32 mph. If so, that's not lying, that's an
inaccurate speedometer.

I know when I took my eighteen year old grandson out for the
first time he said, "We've got to be going 40, at least." The
GPS said 20.

this is getting funny now. I don't know who you should believe either. but
the next time I get a chance I will try to get radar clocked if I can. Also
somewhere there is a major power to weight ratio drop. if his 50 does low
30's and it is probably 50 lbs heavier than mine and possibly his motor
shaft is not as deep down as the Suzuki this thing looks at least 3" longer
than my 9.9 long shaft. that gives you better plane and the prop pitch is
different anything is possible. Happy fishing guy whatever the reason is it
really makes no difference when you come right down to it. I just hope the
guy that started this is happy with his new boat. I'm getting tired of
typing.

Let me add this to this discussion that's gone off track.

The shape of the hull will make all the difference. A flat bottom dory
will get a much higher speed than a deep v hull. Just look at C-Dorys
and their HP requirements and compare the same to a deep v power boat.

I haven't had the chance to take the boat out for a spin yet. Go
figure. It's been over a week now since I purchased it. The Bayrunner
looks to flatten out quite a bit in the stern and since aluminum is
much lighter than fiberglass or wood I would expect mine to go atleast
15 MPH.

Now consider a 3,500 lbs sailboat with a full lead keel being pushed
around the water with a 9.9 hp at 6 knots. I don't find it that
difficult to believe that the other fellow is getting close to 20 mph
on his aluminum boat that weight probably a 1/3 of the weight.

I'm really itching to take her out for a spin and I do hope this great
weather that we're having in the SF Bay will hold up throught the
weekend.

Borrow a GPS from somebody - that will give you a pretty accurate
reading.

Also

That's true enough, but the 9.9 claim seems a little, well, odd for
the same reason - power/weight ratio.

Try the GPS thing - that the easiest way to determine speed and
compare it to your speedo.

I wish I had a GPS!

Finally took her own. It was 92 degrees in the SF bay...unusually hot
for this part of the country.

Just like the owner's son told me it does about 20. I would say more
like 17-18. I noticed that the tilt pin was on the lowest position so
I moved it two notches up. I also noticed that the outboard was
running rich (thick smoke) so I adjusted the mixture. With these two
changes there was a noticable pick up in overall speed.

I guess if one uses it in a small lake the outboard is ok but out in
the bay there's lot of water to cover. My boston whaler with a 40
really flew and it's a bit of an adjustment to this. And the noise.
Wow, that little beast sure screams. I'm definitly going to change it
to a 30+ hp. On the plus side I motored and trolled for 7 hours and it
only burned 4 gallons. It's a great clean smooth outboard.

And I got skunked. No bite.
