Engine Mount Position

OK heres the pic.

This is the side of the front engine mount. As you can see it has a 3 hole adjustment to height. This will adjust the trim. This is an OMC mount that holds a 307 CID chevy and a stringer drive. My boat does have trim tabs, but I would like to know where to place this as to not need the tabs to get her to plane right. I'm hoping that some of you with similar boats SRV 240 Weekender can tell me where you have yours placed. This is the original type settup for my boat, but not the original parts. I got my boat minus a running engine, Most was missing. The moiunts that came with her used the center hole, but the engine that was there was an old car engine. clearly he had no clue.
Thanks for the help.

If thats the front mount, raising the front of the engine will trim the outdrive in towards the boat, this will bring the bow down. If you could find one of the motorized mechanical jackscrew front mounts used on the later 800 series stringers, you could adjust on the fly. I've seen some on ebay recently cheap, like $100. My last boat had that jackscrew setup with the motor and a trim switch on the throttle. I used it more than the trim tabs.

I get what the idea is on how it works. My Dad's boat had that jack screw settup for his original JITTS with the 4 cyl OMC. Just wondering If I can get a good starting point on this settup.

How hard is it to adjust if in the boat? If its not too hard, I'd start in the middle and see how it performs, then move up or down from there once I knew where I needed to the bow to go.

Doesen't appear to be tough. Thats the idea have had if I got no other answer. might just do trial and error.
