power trim on a 30' pontoon
 

This pontoon I just got has a v-4 evinrude with a power trim . Besides
using it to raise the lower end for transport, is a power trim really
of any effective use on a pontoon boat? especially of one of this size
and loaded down with people? I mean it's gong to be a cruise
platform, not a rocket sled.

Trimming the motor really does a lot of good when you are at cruising
speed. You'll notice a few more MPH at the same RPM's and the motor
won't be working nearly as hard because you're not plowing water when
trimmed well.

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.

I would think a power trim on the engine would be great for a pontoon boat,
where the ability to raise and lower the bow may be necessary to offset loading
imbalances.

It's an 85 horse. It will trim that pontoon boat out easily.

Tim,
Might sound funny but when I take my 21' out. I set the throttle and then
trim until the motor reaches its highest RPM (RPM will drop if boat is bow
up or down) without touching the throttle and this gives me the best trim
possible. My experience/opinion anyway.

Thanks for all he ideas. I know that trim works well on my v hulls,
but I've never used a tube boat. And seeing it's not a v or tri-hull
etc, I was wondering about the trim's effectiveness on a two-rail type
system. Yeah, I suppose I'll find out one way or another.

I have noticed that pontoons sit low in the back anyhow, and with
people on it, the things sit low everywhere.

True, this might take a bit of experimentation.

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.

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.

"Trimming" the people on the boat by balancing the load makes more
difference than anything you can do with the motor but a load on that
aircraft carrier you have is probably 10 or more. It is real hard to
get that many people to sit in one spot for long.

Agreed. It will probably be mroe like a portable or powered raft if
anything else
