Stern raised...boat out of balance...ideas?

Wrong motor bracket.

From the picture I don't suspect there is a problem with the stern being to high. The boat has a slight suspended stern leading up to a reverse transom and it is common for these designs to show a bit of rudder with the boat at rest. What seems to be your real problem is that the motor mount does not go down beyond horizontal. The mount that you need should have the same travel down from center as the travel it has when you raise it up. I cannot tell from the picture how the mechanism work but if you cannot get it to go down any further I would suggest you replace it with a mount that will.

There's nothing wrong with your boat!!!

first of all, it's impossible to see if your boat's hull is out of trim without a full length shot of the vessel sitting in the water. As Benny says, the proplem is with the motor mount. You need one with a longer vertical lift. Here's one in westmarine that has 15.5 inch lift, note the mounting pad that has multiple holes for attachment.http://www.westmarine.com/webapp/wcs/stores/servlet/product/10001/-1/10001/82174/10001/784/625/6 Another thing, you need to adjust your motor's tilt so that the shaft is 90 degrees to the water. That's what all those holes are on the motor bracket. If you run out of holes then you need to put a wedge between the bracket and the mount.The removal of the saildrive probably had little effect on the boat's trim because inboard engines are mounted as close to low gravity center as possible, probably right behind the cabin ladder. The 100 or so pounds the outboard adds to the transom would certainly compensate for the engine weight missing near bottom.So....take a look at your boat from a distance, to see how she sits in the water, before you start adding lead here and there. Your OB motor mount is definitely the problem.Another comment: Even when you get the mount issue resolved, your boat's design will limit the motor's performance in choppy waves. The reverse transom will magnify any type of hobby horsing caused by heavy chop. So make sure you keep your hand on the throttle should the lake kick up.

I don't think its a trim problem!

the 28 and 30's had very similar transoms. when at the dock the bottom edge of the stern will normally be about 6to8" out of the water.when motoring it will squatt to where the stern will actually be about 2 to 3" into the water. one problem i see is it appears the motor isn't set in the correct pins. its always a bitch when someone changes an original design in a half assed manner. i wouldn't add any ballast any where. if its not sitting on its lines correctly, then it could be someones moved something very heavy internally. most O'Days are actually stern heavy. I've actually moved some of the heavier gear forward. by the time you get a few people in the cockpit it will really squatt stern down under sail. this will affect sailing performance drastically.Que Pasa?

just a thought...

could you add a shim to the top part of the motor mount to aim it more downwards?

Motor mount is at fault

Check other mounts at your marina and you'll see yours is not lowering to it's fullest.  Just my 2 cents worth. Keep it up, Ctskip
