jack plate on yamaha 150 and 20' center console fisherman

[pancake]

interested in raising my Yamaha 150 2 stroke outdrive on a jackplate so that my motor ,trim pump etc. is completely out if the salt water when its sitting at the dock. the boat is a 1984 20' wellcraft fisherman center console. i've read the posts available and will do it over the winter. Does any one have any general suggestions?

Everything is dependent on how/where the motor was mounted (so not to need to drill more holes).
The base (boat side) of the plate usually works out good if using the highest mounting holes position and adjusting the motor height at the motors bolt holes.
The (normal) 5 inches of travel, coupled with the amount of setback should allow you about 6 1/2 inches of gained height.
Mine is a little lower than normal, due to the fact I insisted on using most of the existing transom bolt holes when we changed from a 20" to a 25" transom.

This is the lowest position possible with mine, a little too deep for most circumstances, given the motor setback.
This may be for good maintaining a toehold in rough seas.

Hey TSUBAKI, that engine needs to go up another hole easily. You'd freak out if you seen how much higher the engine is on my HYDRA, and it still isn't high enough.

I agree FERM!
And I do have one bolt hole left to go up but I'm able to achieve everything I want where it is.
When lifted up and tilted forward completely, I can even change the spark plugs standing flatfooted in the back of the boat without having to lean out and over the motor.
In those photo's above, I had it tilted up just high enough to clear the water.

Notch improvement or jackplate???

tsubaki did you fill the notch on your boat? I've been looking to install a cmc jackplate but i've noticed that my steering system may get in the way and bind if i move the motor back and up with the jackplate. If i fill in the notch i think it would be better and also raise the motor out of the saltwater while sitting in the slip. my reason for raising was to reduce corrosion on my 150 yamaha. How did you fill in the notch?
