That is most like too high. It needs to be even with to about 1" above. Unless you have a some set-back which would allow you to raise it a bit higher.

What do you mean by a some set-back?

Re: getting out of the hole problems

I don't have a jack plate, but I do have 3 holes left where I could raise the motor on the transom. It would be tough to raise without a cherry picker, but I bet 2 people could lift while one person bolted. I do have hydraulic tilt and trim.

You need to lower it, not raise it. Can you take some pics of your set up for us? Take kneel down and take a shot of the motor from around the height of the bottom of your boat so we'll have the correct perspective.

Re: getting out of the hole problems

Based on everything you have said, you are not going to get a good qualified answer without posting a picture of the cavitation plate in relation to the bottom of the hull. If you don't have a digital camera, find one, borrow one, or buy one.

You will get solid, correct information if you post a pic of your setup.

Might need a wedge on the transom to add more "tuck". More "down" trim.

Re: getting out of the hole problems

Looks like it's properly aligned.........with the step up! It's definitely too high in regards to your true keel. That needs to come down like 2" I think.

Re: getting out of the hole problems

Where is your anti-cavitation plate in relation to the bottom of the hull?
They are right, if the prop is too low it will cause the bow to raise more than it should.

You think I should raise or lower the motor?

Having your prop to deep can cause excessive bow rise. For an example say an engine with too long a shaft or too deep. Yours is not like that. Not real familiar with a hull like that one but, I think dropping it is the way to go. The prop does need to be at a certain depth to work as designed. There is some props that can still work
only partially submerged but, that's a different story.

Excessive bow rise is exactly how I would describe what my boat is doing. I will have to see about getting a jack plate so I can lower my motor. Right now the motor can't go any lower.

Re: getting out of the hole problems

well ill chime in on this most bass boats have jack plates this adds setback, the more you go back the higher you can run the lower unit higher. in some cases water intakes are not below the bottom of the boat. my guess since we have no pictures is that you need more tuck, this can be obtained with wedges and a jack plate sometimes wedes alone can solve it. look at the rod on transom bracket if it had them, sometimes they were movable

Re: getting out of the hole problems

also make sure the live wells arent filling up cause there open that adds a crap load of weight per gallon

Are you saying the water intakes are not at the correct height and the motor needs to be lower?

See picture.

I checked the live wells and they were plugged and no water was in them.

Re: getting out of the hole problems

i would start motor at the highest hole first,the motor from the picture shows it does not tuck towards the actual pad.

Are you talking about raising the motor as high as it can go to the fourth hole on the transom?

Re: getting out of the hole problems

you have to start by putting a long straight edge on th bottom of the boat draw a imaginary line through the prop shaft this will tell you propshaft height and trim pos-nuetral-neg if the propshaft has neg or neutral trim it will never plane right.

Re: getting out of the hole problems

i will repeat what i said before.
i say probably all the above, plus you have 750 lbs in people 300 lbs in motor, bass style boat with seats set more to the stern. the boat is just plain tail heavy. you have to balance the load. that is what you did when you moved forward. a set of smart tabs, will help with the planing. i also suggest with that vintage boat to check for waterlogged foam. foam can hold as much as 5-700 lbs of water.

your motor height is fine, that short step will not effect it.

the tilt pin postion is critical, in getting out of the hole, the closer to the transom, it pushes the bow down, farther away the prop pushes the bow up. thus excessive bow rise. bass boat are not great at balancing the weight load, you have to get weight to the bow, to help bring the bow down.
