How to get rid of porpus in '92 Top Gun?
I'm getting quite a bit of porpusing at most speeds.It rides good between 38-44mph trim no more than 2-3 on the indicators and 60-70mph with trim as high as about 9 where i start loosing speed.Anywhere between i can run 1 or less on trim and when full fuel i'm running the tabs.Boats a '92 Top Gun HP500, TRS, 26pitch 4 blade turning out.I also boat on the Illinois river which is usually flat as glass which im sure doesnt help.Looking for advice since i havent had the boat long and quite a bit different from my previous 29 PowerQuest.

Drives spinning out IS stern lifting, the gun has a notched transom and thats one reason why they do that from what I am told, my buddy went from a mistress to a gun and said they are totally different like that...
I also hear 42's do it too...
running tab is probably only way to help it, or keep drives in a tad during cruising, I rarely use my tabs.. but the mistress rides more level even though it too will porpoise way more then my 32 Baja did..
