How big Setback
Hi guys
im running a Fletcher 199 with a 225 optimax with a hydraulic jackplate.
I’m about 80mph top speed with a 27p Tempest plus (blueprinted/labbed), but I’m running to flat and can’t seem to get it up flying on the back pad.
any suggestions to ad a bigger setback or what to do?

Put your motor down and measure where your propshaft is in relation the pad

I just confused cause I’ve got a jackplate and therefore the level from shaft to bottom boat varies

The correct setback and height is the secret to a good life.

Tape a level to the bottom of the pad. Raise or lower the boat on the trailer till it is level. Now, lower the outboard till it is level. Tape a small level to the captivating plate. The one above the propeller where the zink is. Once that's level use a long enough stick to tape to the boats pad and reaches out to the nose of the lower unit. Measure the distance up or down from center of lower unit to bottom of pad. That's how to know where you are with setup

if you setback the motor. the motor needs to be raise up. the water leaving the end of the boat raises up in relation to the pad.

There’s no significant pad on that boat. Most of your lift is coming from the lifting strakes. You will never get the boat to only run on the keel/pad, it’s too narrow. I don’t think you are going to find much more speed. You might try a prop with more bow lift. As for setback, you could probably move the motor back a bit, I’d try a 4” extension between the boat and current plate, it’s cheap. The only problem I see is the motor is already mounted quite high on the existing plate, it’s putting a lot of torque on the transom. It’s also going the make the transom sit lower in the water and on the first shot it’s already precariously low.

How much more speed is the stock lower gonna handle? I'd say without a cone or a sportmaster, your pissing in the wind.
