280 vs. 380
 

Has anyone switched from the 280 kplanes to a set of 380's on a twin 28? How did the boat react to it?

I switched them on my 382 Formula. They made a big difference, I really like them. Back in the day they ran bigger tabs than that on the old 27-30 ft race boats so I think you would like them. I have extension boxes so I didn't have to trim much off them. Just a little of the corner. With out the boxes I would have had to trim a lot more off and wouldn't have ended up with much more tab than the 280. Make sure you buy the right ones, there is a difference in the bolt size of the Kiekhaefer's and the Merc Racing tabs that connects them to the transom plate.

I swapped them out on my 28 apache. I found it helped quite a bit as the 28 is prone to porpoise at 45- 55 mph, not nearly as aggressive tab was required in order to steady the porpoise which resulted in a faster speed...

Thanks for the reply. I have buddy buddy with a set sitting in his garage. I figured it couldnt hurt to give them a try. My pantera will porpoise around that same speed if i dont use alot of tab. Just want to get some feed back from someone that has tried them.

My twin P 28 has the big tabs and you will have to take a small amount off the inside corners or your props will do it for you Ask me how I know !!

Thanks for the heads up. Was this on a twin?

What drives and motors do you have and what is your top speed?

Trs drives, 502ci, runs 82mph.

Do you know how much hp you have?

Has anyone put the 380's on a 24?
