Default Choose a OB for 18' jon

Hand tiller outboards-Which would you choose?

Yamaha/Mercury 30 hp 747cc 3 cyl. $3500
Yamaha 25hp 498cc 2 cyl. hi-thrust model $3200

Suzuki/Johnson 25 hp or 30 hp 597cc 3 cyl. $3100 or $3500

Nissan 25hp or 30 hp 492cc $2800 or $3000

Honda 25 hp or 30 hp 552cc 2 cyl.$3500 or $3800

Going on a 18' Sea Ark MV1872 heavy duty (.125 aluminum) "super" jon
boat (80 hp max?)
fuel efficiency most important. Cruising at moderate speeds, around
15mph is the goal.
Is this underpowered @ 25-30 hp?
Thanks!

Not an expert on Jon boats, but my brother's which is an 18' or 19'
with an older 25hp Merc does around 28mph if memory serves me. I
don't know how 'heavy' your heavy duty Jon is, but would not think you
will have a problem doing 15mph with any of the motors you listed.
Why not try deciding which one you'd like and put it on the dealer to
guarantee the performance you're looking for. Seems to me you're
not asking for a lot and a dealer should be able to figure if this is
enough and at least guarantee that much performence. Just a thought.

Rule of thumb if a boat is rated for 80hp then take 80percent of that
number and that would be the average for your boat, and it looks like a 60
to 65hp would be the ticket

Is there anyway you can get a demo ride on a boat equipped with one of
hte engines you are considering? I think you're going to be disappointed
with the "efficient" cruise speed.

That's what the dealer who sold Mercury said... He suggested a 40 hp as
a minimum. He really thought I should get a console for the boat and put
on a much bigger 4 cylinder engine. That would blow my budget!
Here's the boat's specs...
MV1872 Specifications
Overall Length: 18 ft.
Beam: 95 in.
Bottom Width: 72 in.
Side Depth: 28 in.
Gauge: .125 in.
Rating: 80/130 hp
Weight Cap: 2075 lbs.
Persons Cap: 12/1650 lbs.
Approximate Weight: 750 lbs.
Transom Height: 20 in.

It was sold in a foreclosure auction with a very basic single axle
trailer (13" wheels) for $1500 2 weeks ago. It is used (2001) but in
excellent shape. No motor. New, I estimate the boat and trailer to be
about $5000, so I think I did OK so far.

Joseph,

I'm familiar with that rule of thumb, but, a) I personally can't
imagine using a tiller motor of that size, and b) now that I see
he's posted the specs on the boat, it's much bigger overall than
I was imagining.

I have seen 100 HP Mariner tiller steers on two different boats now. One was a
large jon "work" boat on the Mississippi River. The other was a Lund (or maybe
a Sylvan) walleye boat on the Illinois River. I have personally operated my
friend's 60 HP tiller and there was very little pull from the prop when
accelerating. It had decent instrumentation - internal speedo, tach, temp, and
voltage that were mounted on the side of the boat.

Maybe you can take this a step further and ask them to demo one or two on *your*
boat. The dealer will probably have to be on the water for them to accommodate
you.

Ya think? Naw, the little outboard bracket on my Parker is for an 8 or
10 hp jobbie.

How about your boat, Dan?Can he take it out for a trial?
