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

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.

What do you expect from a piece of **** Bass boat?

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

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:

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.

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?

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.

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.
