Motor height...Skool??

[draglink]

Skool had given me some advice about this earlier, but anybody feel free to chime in.

Just pulled the V out for the week and have studied the way the motor is hung. Iam trying to get more bow out of the water at speed.

If I trim the motor all the way down- straight edge along the bottom....the edge hits exactly level with the cavitation plate and then ends about an inch lower at the outer end

Looks like the motor needs to come down a hair to me....thoughts?

That is the starting point.
Go up one bolt hole and see if there is any cavitation (ventilation) during various turns, starts, etc.
One characteristic of being too high is a grinding or rumbling sensation not noticed earlier running wide open.
No real noticeable vibrations from going up one hole, try the next one up and see if it performs better or not from the last.
The V's seem to like the bow a little lower than every other boat, don't judge them by others. They perform better almost flat instead of trimmed up.
This is a picture of a 20" transom and a 20" motor close to the best location. The cavitation plate is a little over an inch above the bottom of the boat. So don't be surprised of your adjustments.

Rereading it and considering the horse motor you got, you are very close to perfect with the engine height.

cavitation plate should be even or a hair above that stick, unless you have a bracket then you need to be up 1 inch for each foot back you go.
motor trimmed all the way down will be bow in water try trimming a bit better

My cavitation plate is just a little more than an inch above the bottom of the boat....so that sounds about perfect.

I never run with motor trimmed down.....always with positive trim...trying to get the bow up. In fact I probably run to much trim bc I cavitate in turns and have to trim down to grab a little.
