I did some searching and found a comment that 1/2" toe out on the gladiator helped top end.

When making this adjustment, What kind of handling characteristics should I be watching for? Any potential to have a situation get out of hand or is it just going to be a matter of faster or slower...period?

Oh yeah, is the 1/2" measured from nose to nose up front versus the trailing edge of the skeg out back? ie 1/2" wider in front than in back?

MobileAmerican, I suspect you know this as do others.

1/2 inch is too much. if your spining out they should be toe'd in 1/8 inch. this gladiator with 700+ zuls, its, and sportmasters, spining a set of 30 4bld bravos ran fastest set up this way. 111 on its best day. 105 106 every time out.

heres a couple pics.

I am turning in. The factory had them nuts on zero toe in. I think it was dhlaw said they liked the toe out on their race boat.

Mine is in the same power/weight speed category as your reference boat though.

Today I tried a more modest 1/4" toe out and 4 blade 32Ps and achieved the same top end with a full tank of fuel and a passenger (turning props in).

Thanks for the perspective Monstaaa.

Now, did you have to fuel your diveshaft engine a extra to keep up with the non shaft motor? I would like to see if that could get equalized in the props.

"fuel your diveshaft engine"???
Pls expalin, the boat he is talking about is a side-by-side boat, not a staggered boat like yours.

The toe adjustment is done to adj for the movement under load. The propellers try to come together when swinging in. If you toe in say 1/16 to an 1/8 they end up parallel. All boats are different and it may be hard to recognize fine adjustments.

Thanks jim

40ICBM; My mistake, I thought his was staggered too.

My forward engine uses about 5% more fuel than the other.

I am searching for ways to overcome this. 1st on the list is a lightweight driveshaft. The stock Merc unit is very heavy.
