Do or did anyone ever make a drive spacer for the TRS drive?
Thanks, Steve

Not that i know of !!!
there to long anyways ?!

Yea I sort of figured that. My boat is really heavy and slow so I'm wondering if the drive needs to be as high as a lightweight faster boat. The reason why I ask is because I'm chasing a porpoising problem.

Porpoising is most if not all the time ,when the drives are to low in the water.

How heavy is the boat and what is it , and what kind of power ?

It's a 1978 23ft SeaCraft SeaVette which is the same hull as any other 23ft SeaCraft fishing boat, just the lay out is different. It's powered by a FWC ZZ502 and weighs about 5400 lbs wet. It's very stern heavy.

Yep ,,,if its stern heavy it needs a higher X on the dpethfrom the drive !!
To push the stern up more .

The center of the prop shaft is 7" below the keel, which puts the cavitation plate 2" above the keel. Is there a shorter lower that will bolt to my TRS upper and work for me?

if its only a 23 foot boat i would convert to a bravo !!

U could bolt a Speedmaster II lower on there butstill not high enuff.
Everybody thinks its about the cavitationplate ????,,,,, its about the prop ,,thats whas pushing the boat !!!
You are actually pulling the stern down even more with a lower drive hight then u would with a higher one ,,,since the drive always tries to go under the boat in motion ??!!
Does that make sence to u ?? Or is my half a$$ explination not ok ?? LOL

So if I go with the Bravo drive then what should I shoot for as far as the depth of the prop shaft? And yes, it does makes sence. Thanks

I would try and move weight around in the boat. Is there anything you can move to the bow of the boat or fill up a water tank?
