The Checkmate Bounce

wait this comes from a guy that doesnt know how to drive a boat:sssh: [/QUOTE]

If you ever want to learn my fee is $50 per hour with a 2 hour minimum.
 
With my 219 I pretty much never hit the trim button unless I was going over 45 but I found that I could nail it, get it up to 60 or so, trim it out and then back it back down to about 40 and it would ride there with the trim still up. Thats always how I did it in smooth water, plus its an excuse to nail it right when you get it wet!!

My 259, I don't think I have had enough seat time in it. If I am trying to run below 45 it hops pretty bad, I have played with the tabs and sometimes it seems to make it worse. With the tabs all the way down, it wants to lean over real bad in the turns. This is the first "big" boat I have ever driven though, I don't know if it makes a difference but the tabs are The big livorsi tabs, I have heard that they don't help this problem as much. To get around it, I have just been cruising at 50-55 which seems to work really well in rough water, but what sucks is that my dad's rinker and my uncle's starcraft only like to go about 30...or they just only like to go 30. Thats ok though I still love going to the lake with family.
 
Just keep the drive tucked in until you get over 4000 rpms. It will ride nicely at lower rpm's as long as you dont add any positive trim.

Screw the tabs, keep them up and keep the drive in. I cruise at around 2800 rpm mowt of the time anymore and it rides nicely.
 
I keep my drive tucked till on plain..Which is seconds.. Then trim it to get the boat out of the water. Sometime it does a little bounce but I just touch the trim down and all is well... I see some boats bouncing as I go by. And I say to myself, Sea Ya !!:sssh:
 
I noticed the same thing on my '08 270BR. My other experience is with a 93 Mariah with the 454. The mariah is heavy and doesn't bounce. The answer I have right now is just to not run at that low a speed. I really don't get up on plane until 35 anyway. One shop in my area claimed that I needed more cup on my prop and that would fix it. Anyone heard of that solution?
 
O/B's can fix some of the porpoising by going up ever so slightly in engine height.

Anyway, even if that doesn't completely kill the porpoising, just hold off on the trim.

Trim tabs are the serious answer.

True,i had trim tabs on my persuader
and no issues.
 
Last year I didn't seem to have this problem, but this year with added set back she has a bad bounce. slight trim and around 30 MPH and she'll give you an ab workout - trim the engine down and it goes away.
 
I love my K-planes however they are like puttin on the brakes. I drive through it and raise them after about 50 or so. I can get 77-78 with or 83 without. I noticed less porp when I pulled my Spinnelli 4 and went back to my cheap ol Mirage 3.
