What did I do wrong?

[tomandwendy]

As a few of you may remember, a couple weeks ago I asked about taking off the engine hydrofoil, well I did so and started out in the morning 6 am and I admit it took a little to get used to because the boat would bounce up and down. I think its called porpoising (Did I spell that right?). But I did get it to plane on the proper place and even gained 4 mph.

However later that day when the waves got a little choppy, I could not get the boat to plane out at all, it bounced and bounced the entire time until I just ended up fast idling all the way back to the dock. I even tried not even trimming the boat at all and it still bounced badly (trim all the way down) Was it just how I was doing the takeoff to plane or am I missing something as far as controlability?

If I could take a guess, if I trimmed the boat just a tad, you could hear the boat losing its bite...does this mean the engine is too high?

Thanks for any help

Tom

you need Trim tabs .

Re: What did I do wrong?

your motor is either too high, or you need to trim in, porposing is a trim problem

I kinda had a feeling with that, but my engine was trimmed all the way down, I was not even able to trim at all once boat started to plane.....for now I guess I need to put the hydrofoil back on until I can get some smart tabs?? (suggestions?)

Yes, I know what you mean, I've had to do the same thing with my boat, put the hydrofoil back on because it beats having nothing, until I get trim tabs.

I did the same thing once and put the hydrofoil back on. Didn't need the trim tabs with the HF on, but would have if I decided to leave it off. I figured that it was a lot easier to put the HF back on vs installing trim tabls. Cheaper also.

Re: What did I do wrong?

I don't rememmber your original post, what type of boat and power? Are you sure that the trim pin is in the farthest back position?

 

[oops!]

Re: What did I do wrong?

check that pin....or have someone that knows check it......

unless youve got a wacky power set up....you should plane no problem......trim in or out.....the trim is a fine tuning adjustment once on plane.


if you cant get outta the water with out a whale tail....your really underpowered
