For a big motor I'd want a working power trim.

Absolutely right for all of the previously mentioned reasons. There
is no one "correct" setting for different loads and different sea
conditions.

You really should be able to adjust your trim while moving.
I found it very helpful even with a 5hp on a 12' boat.
That was easily done manually.

Been my limited experience with 5 horse motors that you get a choice
of about five notches. If it was infinitly variable, you would want to
adjust it underway, but that is not necessary to pick the best of five
by trial and error.

I don't think I've ever seen a small outboard like that with hydraulic trim.

Dillweed, it depends on the type of hull, weight distribution and how
you want the boat to ride.

Flat bottom? No not you, the boat.

You should learn some restraint. You are an idiot and you have nothing
to offer. It's best to ignore these on-topic posts and stick to your
political trolling.

I can tell you that one notch position makes quite a difference.
When I bought my open aluminum boat with 25 hp ourboard from a fellow poster
here, I just had to mess around with the adjustments.
The boat wouldn't plane right...the bow was sticking up too far and the
speed was disappointing.
I could make out (slight dirt stain) where the trim was originally set...and
after confirming this with the original owner, I set the trim in that spot.
What a difference...up on plane in a couple of seconds and the GPS rated me
at just over 27 mph.
Would a different setting be required with passengers...or in much rougher
waters..maybe.




Wow! So rowboat with small OB = "open aluminum boat"? It does sound
fancier, dummy. And 27 mph is amazing! At least it's faster than a Segway.

You will need to experiment with the setting. Correct porpoising by
lowering the trim. Correct bow steer or flat running by raising the trim.
Sometimes changing the trim even 1 notch fixes one problem but creates
another problem. If you cant get the trim right by setting the engine and
or distributing the weight in the boat then try a doel fin and or
changing the prop pitch. Make sure the engine stays in the proper WOT RPM
range.

Why not fix the power trim? Problem with the fixed notches is that a
position may work well with one person aboard but not very well with two
or more. Boat loading affects the ideal trim.
Also, I don't know where you boat, but in the ocean the power trim allows
for easy, underway adjustments for changing sea conditions. Lifting or
lowering the bow a bit in rough chop helps keep you dry and can smooth out
the ride a bit.

There's no power trim to be fixed. All that remain are the two rocker
switches. I'm looking for a used unit, but so far no luck. Then I would
have to find someone who knows how to install it. But yeah, that would be
the ideal.

I didn't see if you said how big it is, but there are several
aftermarket manufacturers of trim units like CMC and Panther.

And your value overflows the newsgroup. You spend 90% of your time
