The trim can make a little difference but not that much. I have a 60
and had a 75 on a 20' Harris. I could play with the trim and get about
a 1 MPH swing. Trim can help a lot in shallow water operation tho.

An 85 is not going to give you tremendous performance on that boat
anyway. That motor is old enough that the 85 was probably BHP and not
at the prop so it may be more like 70. If you really figure out you
like the pontoon boat experience I would be saving my box tops for a 4
stroke 115-150 class repower.


Thanks Greg. I DO have a 115 v4 saved up for the perfect opertunity,
And it may be used.

I figures since a pontoon sits low in the back then trimming it would
probably jsut push the back end lower, because I don't think the front
is going to raise. Especially "to the moon, Alice" before planing,t
hat is, if a pontoon actually 'planes'. It probably does but not as I
know it. I'm a v-hull boater, not a barge operator.


Before I bought my first small boat in Jax, I rented a nice pontoon boat
for the day from an outfit on the St. Johns River, near where it empties
into the Atlantic. It was a "somewhere in the 20's" in terms of length,
and it had a 115 hp Merc on it. Nice boat.


Well, the trip out to the mouth of the river was uneventful. It was too
rough for comfort for the pontoon boat between the jetties, what with
the wind, the current and boat wakes, so we messed around near one of
the beaches on the south side. Going back, the wind kicked up and the
trip back to the dock on that pontoon was not very enjoyable. Made me
think a lot more seriously about buying a small v-hull boat, rather than
a pontoon boat, for the river, ICW and occasional near shore Atlantic
fishing.

It'll only do about 40mph... big, heavy, and lots of drag. But it's
comfortable and will snatch a slalom skier up from a deepwater start.
Did you ever see the video?

The speed isn't that important to me unless a storm brews up while
we're out. Then it's nice to be able to get back to the slip quicker.

Here on dial-up it's hard to watch vids, ut I've seen the ones witht
he pontoons going aout 85-80 mph. Screaming engine too!


Several years ago, a guy put a Mercury 200 hp "Black Max" on a 24'
Harris and it would get after it. The pontoons made a wierd 'singing'

It was really fun to ski behind. almost no wake.


Now concerning engine power, sometime ago I bought a derilict boat for
the outdrive, and I do have a 120 hp 4 cyl mercruiser I could park in
it. Which I doub't would have the torque of the v-4 Johnsons, but
would be more economical. Maybe not as much as a modern 4 cycle
outboard, but Hey, you run what you brung, y'know. Also, If I decide
to keep the thing, I may do some work with some hybrid gas/electric
ideas .....

Once in a blue moon you'll see one in our harbour, but that's about it.
I've never seen one at any of the local boat/yacht clubs situated on the
ocean.

My old Bennington was a 25' tritoon with lifting strakes and a 150hp
Johnson. *The trim on it did make some difference... in a straight
line you could affect the speed and bow lift a bit. *However, when set
at the most efficient for running in a straight line, it would
ventilate the prop in anything over a gentle turn. *When skiing or
pulling a tube, I'd have to work the trim a lot.


The new Premier is also a 25' tritoon, but it has a different center
pontoon design. *With the Yamaha 250 on it, the trim has virtually no
effect on the bow lift or speed... it seems that it's planed out and
doing all it will do. *Nice thing is that it's hooked up solid with no
ventilation in the turns, and it'll turn nearly as sharp as a V hull.


With your boat's length and having two 'toons, I'd be surprised if you
see much of an effect with the trim, but I may be wrong. *Let us know
what it does.


Cavitating the prop in a turn is common with pontoons, particularly if
the motor is mounted high. You are *going through the wash of the
outside pontoon on a turn. Perhaps your 250 is heavy enough to hold
the stern down more. Is it a longer shaft or mounted lower?
My boat is horrible about blowing out on a hard turn at speed but I
gave that up for shallow running ability. My motor is 4" above the
stock location.- Hide quoted text -


I always thought it was because of the center pontoon being right in
front of the motor. With the old boat the dealer said it was normal,
and I had to expect to work the trim a bit.

With the new one and the 250, I wondered about the mounting height
myself, but taking a look at the foot as I'm underway it looks like
it's running about as deep as I understand it should. I think the
design of the center "PTX" toon and the way the boat turns, with the
rear squatting, banking, and lifting the outside toon out of the
water, it just has cleaner water and is "forced" to stay hooked up.
Watch the video I linked in a previous post and you'll see what I mean.

We have pontoons 10 miles offshore in the Gulf all the time but the
water is usually pretty calm here.



There are always fools doing things in boats they shouldn't. Going 10
miles offshore in a pontoon boat on a relatively shallow body of water
where storms can come up suddenly sounds like a competition for the
Darwin award. Well, Loogy would do it.

Using that trim, you might be able to achieve the all-important 88 mph
speed, which will push you and the DeLorean barge backwards to the
future.

Answer...try the trim and see what happens, but with that small a
motor and that large a boat, I doubt it will have much impact.


Great response: try it

If you have no idea, you don't have to respond, Harry. I know how power
trim works with a V-hull. I had no compulsion to respond in reference
to a pontoon, why did you?
