Interesting problem...
 

A friend on mine just bought a used Stratos 20' bass boat with a 250
Yamaha Vmax. He called this afternoon and asked me to take a ride
with him because he couldn't get his boat to plane right.

We met up at Webster Lake and took it for a ride after checking
everything over - everything seemed to be working, nothing out of
sorts with the hull.

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.

We did - he's lighter than I am, but we both sat on the front deck -
didn't help.

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.

Not an expert in such, but I was going to say . I think the guy needs
a jack plate.

Yeah - that was a thought. My own experience with jack plates would
seem to indicate that it would help more than hurt.

And as it happens, I have a mechanical jack plate sitting in the
garage.

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

In my case, a jack plate wasn't required. The bolts holding the engine on
the transom were removed with the engine strapped to a fork truck. It was
either lowered or raised (can't remember which) by one mounting hole and
reattached. It made a huge difference. The chine walking was scary on
that boat when making turns at high speeds and the porposing was obviously
annoying. The motor height adjustment completely eliminated both. It
didn't take much.

I'll have to take a look at where it's mounted on the engine bracket.
It's a short shaft, so I imagine there isn't a lot of room to play
with.

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.

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

have been around a long time.

A friend on mine just bought a used Stratos 20' bass boat with a
250
Yamaha Vmax. He called this afternoon and asked me to take a ride
with him because he couldn't get his boat to plane right.

We met up at Webster Lake and took it for a ride after checking
everything over - everything seemed to be working, nothing out of
sorts with the hull.

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:

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.

Dan, I lost the post, so I was replying in general to the original
problem that Tom was describing. Sorry for the confusion. My bass boat
has a jack plate just for the reason you stated, I like to get up and
personal with the fishys some times!

Hydraulic or manual? Can you post a pic of the business end over there
---?

Sure, I'll try to take a pic tonight....if I remember! Mine's hydraulic,
runs just like a trim motor.

Interesting problem...

I'll keep an eye out for it!

****, forgot all about it, sorry! I'll try to get it to you before I
leave for Chattanooga for a little R&R! I'll tell you, people who
haven't spent time in Chattanooga in the last few years don't know what
they are missing. One of my favorite smaller cities in the U.S.
