porpoising???

[jlaak5]

Hello all,

  Please forgive me if i sound like I don't know what I am talking about, I am a new boat owner   I have a 192 bowrider that seems to "porpoise" rather easily after acceleration.  It seems to be OK once I adjust the trim, however; it seem to be a problem that I am constantly "chasing"

  Is there something that I am perhaps doing wrong, if so what are my options?

Thanks all,

Jim

It is a "normal" occurrence if the boat is over trimmed.  Start off with the drives trimmed all the way down...once on plane trim up to achieve optimal speed/rpms......there is a fine line at which the boat will start to porpoise.  Ideally you are chasing higher speed at the same throttle point by adjusting the running angle of the boat.  If you overtrim it will porpoise and you will need to trim down to stop it.

Thanks Greg,
 
  So long story short, it is a trim issue and getting used to the correct setting.  That is good to know.  I guess I will just have to continue to work with it and get used to the "feel"

A lot of science crammed into a boat just so you can figure out the "art".....

Yes,
 
  But it will be fun learning the art!

Adding a pair of trim tabs will help/solve the problem too!

Our 192 also porpoised very very easily,  would hardly take any trim untill it was bouncing.   I did some research and was going to put a set of Smart tabs on it. (but we traded it in on a cruiser) Give it about 1/2 hour researching this site and google and you will find others with the same boat and concerns along with pictures of the tabs installed.

I had the same problem with my 192.

My problem seemed to stem from the fact that the majority of the weight was in the back of the boat:  engine, fuel, people, coolers, storage, etc.

Putting people/weight up front helped tremendously.  I went so far as to dismantle some of the front upholstery to add ballast up in some of the unused "dead" space and started carrying anchor etc. up in the bow storage.

As mentioned by others, proper trim is essential as well.  Problem is that trim down can be rough riding.  Trim up is smoother but porpoising starts, so move some weight up front.  Or move up to a 232 which isn't prone to the problem.

Good luck.
