Got on the water and it's the oddest thing - no matter what trim
position, the boat would porpise (pitch) at speed. Vary the speed and
you'd get a yawing action - trim made no difference. No roll to speak
of.

All the bolts are tight, properly torgued, the prop is symmetrical,
the skeg on the outboard is straight, keel is straight - no obvious
repairs.

Any ideas? I'll admit it - I'm stumped.
Try putting 100 pounds of weight at the bow and see if that helps.


I had a Robalo that handled like that. No matter how I trimmed it,
it porpised and chine walked in turns. I mentioned it to a guy at
work who took it and adjusted the mounting height of the engine on
the transom. All the porposing and other squirrely handling symptoms
disappeared.

That was my first thought. You could also try a small jack plate.
Here's an example:

http://www.bobsmachine.com/

Email them - they are very helpful. They told me I wouldn't gain much
on my bass boat (alum w/90HP) so they seem to be honest people and
they have been around a long time.

It could also be a result of weight distribution.

If you are replying to me, I didn't email them specifically about speed.
I was (an still am) considering a hydraulic plate for shallow water
fishing. I asked about performance improvement and they were very
honest in their opinion.

The engine is mounted in the wrong set of holes, maybe. It's also a lot
of engine weight for a 20' boat.

Have you ever *seen* any bass boats, WAFA? I've been on a 20' Ranger
with a 250 Verado. How's that for heavy?

Just a clone. Harry's almost as childish and nasty, though.

That asshole is miles ahead of WAFA. I've had him blocked for months
and I really thought he was gone.

Check to see if there is a hook in the bottom. May have set on a bad
trailer without enough support.

Given the available information, the only thing it *could* be is that
the motor is mounted too low.

Has it ever planed correctly? If so, what changed...

Don't know - it's a used boat, low hours Yamaha. We're going to take
it out again this morning. He owns a independant car repair place, so
we're all set with lifts and such.

I know on my Ranger, I had problems with the FICHT short shaft engine
on the 620 based hull - it was never quite right and just playing with
the fixed height positioning didn't solve the problems - some would go
away, others would show up.

It wasn't until I put the jack plate and 25" shaft engine that I could
really dial in the engine positioning to solve ALL the problems in
addition to gaining 6 inches in length which also helped.
