How to stop a 30 w/ OB's from porposing ?
 

Just picked up my new boat she's a 98 30 with 03 300x's. Starts to porpose at approx 60mph and continues to do so until the 80mph mark. Nothing outta control just annoying ? I know a tunnel tab but any other way to cure ?

My 30 with Bravos did the same thing.
Just don't spend much tine running between 60-80. :D
It what I did. :drink:

Throttle up........Adjust trim........These boats have 2 speeds fast and idle..

You will not stop it. Like Speed2lead said, boat was made to run fast.

took her out today for a few hours. seems like in a 1 ft or better chop, once ya hit 60, a little trim and 80% of it goes away. annoying in flat water but then again i havent been using the trim at all til today. was a test and tune day and plenty more ahead. Thanks to all for the input. Robert was good to see ya and thanks for the compliments.

On a flat day you need to be doing 80 and up to get rid of it!

they don't like flat water, you need a little chop to run fast anyway, otherwise it just wants to stick to the water.... i rarely notice the porpoise because it usually matches the chop at LOTO and i just accelerate threw that speed range.... and mine really only will do it around 65-75, but the sterndrives might not be as sensitive as the O/B's would be....

I have the big tab on my 05 30' and use it to 80-85. I don't run the boat on flat water much, mostly ocean running. I ran Havasu last weekend and used the tab till 85 on the flat water. Just a little tab goes a long way at 70-80, then I lift it flat past 80-85. I only used it getting to 85 but I ran the boat at 90-100 all day long never dropping below 90, only when the IMCO ******* tried to take my bow off at 90, guess he didn't like the idea of a 30' with wackers getting ready to pass his ass.
