Hey guys,

i will be installing a new engine in my 26zx, 555ci 600hp engine....


what decent speeds should i expect ?

my current prop is a Bravo1 24p r/h 4blde......

thanks

Mid to high 70's. It takes around 700 hp to break nicely into the 80's

Some of it will depend on drive height, prop & bottom set up. They came in a few different flavors. Regardless tho 600hp in that should at least get you mid to high 70's if you are not running in a high elevation. Yes, you usually will need over 600+ to get in to the 80s.. Jamie / Lakeside

Yes, and you will need another prop

current speed with a 502 415hp is about 64mph on gps.....does an extra 185hp have the potential to gain 10-12mph ?? at least i hope so.....lol

You will get 10 easy.

She is a heavy hull and loosens up as you go faster. Mine does not even hook up well until you get 60. It has sort of a pad on the bottom. You may experience a little chine walk in the high 70's as it climbs up. Once you get her to 80 or so, it settles down. I have not driven the hull with 600 hp. I have with 700 and that pushes it over the hump nicely. You will be right on the edge.

The 26ZX is great between 80-85. Very happy at that speed. At 90+ in glass smooth water it feels like you have a bunch of marbles under you. Not crazy but loose. A little chop helps. At 90+ it will get out of shape if you hit a side wake. Above 100 you will be more worried about hitting side wakes than driving the boat and watching gauges. It kind of feels like sitting on a time bond while holding a hand grenade at that speed.

Enjoy. The 26ZX LOVES power. K planes are a big plus when running in that transitional high 70's area.

Hey Bill is that you ? i kinda recognized you when you mentioned that you took the boat over 90 and 100....and i dont think there are a lot of people out there who did this job....its "DonZi" from the Donzi registry !! recognize me ?

Yes, it is me.

I have heard of one or two that have done the big power thing in a 26ZX. I dunno anyone that keeps it.

I did recognize you after I posted. Keep up the good work and enjoy that ZX.

Oh Yeah !! The engine has finally hit the country......only 48hrs to go and i'll have the beast in hand really cant wait!!!

Finally the engine is sitting in my Garage!!! i've been waiting for about 5months for this machine to get here......

now the real deal begins.....installing the engine in the boat and testing it to see how it goes!!
