How much of a performance will these upgrades create? I know jack plates will allow me to get a litter skinner, but what other perks do these add ons have? Thanks for the help.

Trim tabs are a must for any boat fishing open water IMO

Jack Plates allow you to raise your props higher which creates less drag. They have hydraulic and manual Jack Plates along with different set-back options. Trim tabs can help out getting on plane, and help compensate for unbalanced loads. Both basically help out on performance of a boat depending on how they are setup.

Trim tabs are a must! Level the boat out, lower boat when running in chop, getting on plane faster, etc. jack plates are nice too but not a must like trim tabs.

A jack plate lets you raise/lower the engine to find your optimal performance and economy for the current water conditions. They will also help getting on plane in shallower water, with the right prop.

Trim tabs will help getting on plane with a load and help you balance out an uneven load once on plane. Be careful though and select the correct size for your boat. Trim tabs can get you in a lot of trouble if they are oversized or even installed incorrectly.

reds on reds on reds, is that your YF24 in your profile picture? That is one of the few boats out there that run better without trim tabs.

davidwademarine nailed it.

For instance, you find that perfect spot cruising. The boat starts to porpoise, tap the tabs down some (bring bow down) and the ride smooths out.

Same it things get a little choppy and your passenger up front has a bad back. pull the bow down for a smoother ride.

A combination of tabs, jack plate and 4 blade prop helps jumping up on plane in shallow water.

Newb question I know, but do you want your trim tabs and motor trimmed up or down when trying to get on plane?

I know the boat runs through chop much better when trim tabs are down, and that you get much better efficiency - more mph at same rpm - when trim tabs are up and motor is trimmed up a bit (if water conditions allow it), but what are the rules for getting on plane?

tigerfan4120, ideally you want your boat to be able to get on plane with engine(s) trimmed all the way in, jack plate all the way down (if applicable), and trim tabs all the way up. Trim tabs should only be used to assist getting on plane, they should not be required to get on plane.

For planing off in shallow water you will have to find the right combo of tab position, jack plate height, and engine trim at neutral or slightly negative.

reds on reds on reds, a man can dream though, right?

I guess you are talking about "the hole shot"?

For instance, the boat is in a small 2 foot deep area and you want to get on plane and make it over a 1 foot shallow flat. In my skiff (I'm sure every boat in a little different) I would start with the tabs down. Full throttle and a sharp turn port or starboard and she's pops on plane. Bring the tabs up and back off the throttle (raise jack plate if necessary) and I'm able to cruise over that shallow mud flat or grass bed.

It's a learning process. Ask me if I've ever run out of water. YES

Looks like most of you know already.....trim tabs a gamechanger. Thought they were a gimmick forever, didn't get em on first bay boat but have them on second, night and day difference. Learn to use them in varying conditions and they'll open up far more capability for a boat

Both are a must have in my opinion. I have a 22 ft skeeter bay boat and both help me get everything I can out of the boat with both speed and comfort

Trim tabs and hydraulic jackplate were a must on my Ranger Banshee. The hull was designed to get skinny, but the ride was terrible without adjustments. The boat would porpoise without trim tabs. The jackplate was used in the shallows a lot. Lift the engine, bury the tabs and go full throtle and I could get on top in less than a foot of water. As soon as I got on top, lower the jackplate to stop the cavitation and slowly ease off the trip tabs and I was at full speed in a duck pond. It was quite nice. For the typical boat, the jackplate wasn't necessary.
