38 Powerplay Extension Boxes ????????
 

A friend of mine is about to purchase the last 38 Powerplay to come out of the factory, he really like's the boat and all the options, but has a question about to install extension boxes or not???? He has Sonny Lenard 615 C.I. 800 H.P. nataural motors. He is about to have the boat rigged in the next week and wanted to know plus or minus to boat handling and speed's. Thanks for the help.

hey who is rigging the boat?

Re: 38 Powerplay Extension Boxes ????????
 

Is this the one thats going to get #6's?

Re: 38 Powerplay Extension Boxes ????????
 

He is going to have Imco extremes, Active Thunder is rigging the boat.

If you have a 35 - 38 foot twin, V Hull, with extension boxes, do you like them? Do you wish you did not have them? Can anyone compare the same boat with them as to one without them?

boat's too heavy and will have too much hp's to add extension boxes....

Re: 38 Powerplay Extension Boxes ????????
 

I am not a fan of ITS's on V Bottoms. They seem to work great on cats, Never seen a V work good at all. Most of the time it will not plane well, has too much slip, and top end does not seem to get better. Never can seem to get any prop to work with them either.

Just My 2 Cents.

Don't waste your time hanging bravos behind 615ci motors

He goes through a couple a year

hes better off with 525's, the drives will last longer and.... an extra bravo in the garage for a quick swap when a problem accurs is not a bad idea...

I have extension boxes on my 386 Sonic with XR's. Powered by 575 SCi's and it eats the XR's at least once a year. I was told that I would have better luck with the drives without the boxes. From what I understand, the upgraded drives still use Mercs gears.

The Powerplay may not be as heavy as my Sonic but with that hp it won't take him long to realize that he made two mistakes. One extension boxes, the other XR drives.

Re: 38 Powerplay Extension Boxes ????????
 

Can you compare the handling, Hole shot, Cruising Speed, & top end with a 38 without extension boxes?

Re: 38 Powerplay Extension Boxes ????????
 

Sounds like a perfect case for Konrad's new Bravo replacement drive - good for 740 lbs-ft and the tranny is in the extension box.

Re: 38 Powerplay Extension Boxes ????????
 

I agree with the Konrad drives. I think they will break the difference from a bravo to a 6.

I disagree with extension boxes on a V Bottom for pleasure boating.

Re: 38 Powerplay Extension Boxes ????????
 

You need to be more specific on V-hull. Ventilated or non.

Re: 38 Powerplay Extension Boxes ????????
 

All boats I've seen with them have been Ventilated.

You are bound to know more about this than anyone posting here. I'm just wanting my friend to get the best setup on a boat he is very excited about.

Re: 38 Powerplay Extension Boxes ????????
 

My opinion would be no on my 37 AVH and yes on my straight Vees. However we've got apples and oranges with the AT and PP.

I will consult with Sullivan from Performance Marine this weekend on this. He's done all of the above including Pulse drives on the 38 PP.

My feelings are that the boxes confuse the center of gravity on the steps which would translate into ill handing.

Re: 38 Powerplay Extension Boxes ????????
 

No, I couldn't find anyone that has the same setup that I have without the boxes. It was suggested that I removed them after spending a lot of time and money taking the boxes off and having them powder coated. They were then put back on with a lot of 5200. Maybe when I have to pull the motors again I will consider it but for now they are staying on.

When these XR's break and I know they will, I'll try one of the beefed up XR's with Imco shorties. My X dimension is too low and that's not helping the drives.

Sonic thought it was a good idea to put the boxes on the boat. Straight hull, 650 hp, 32p labbed Bravo 1 props. Original power was 550 hp.
