2002 252 Islander speed question
 

Does anyone know what kind of speeds I can expect for this boat with 502 built to 500 HP?

This winter I'm going to have a 502 built.

Thanks

Russ

I would say 71-72

Baja
 

Faster on the Ocean.
We just got one and its a kick arse ride.
If you meet up with the mercury guys they can change the chip in your computer...

with 2 people on board... 70-73 with several people 60-65


thanks

Re: Baja
 

Just curious....What year and which engine do you have? I have a 2002 252 Islander with the 496 (non-HO) but it seems to run a little rich. I'm wondering if a chip would help.

Factory issue.
The chip can be adjusted... The Mercury guys at the races offered to program it for us for a small fee. Usually a few hundred bucks.
If they tweak it you will get a little more speed out of your boat.

I use the front right cabin as a rest room for us girls. Its nice size and easily fits a porta pottie. WHen we are out working on the races, we spend 8 hours a day sitting on the ocean making sure noone wrecks.


I also read something about putting synthec in your boat... makes it go faster. Look through the forums... I was thinking of passing that on to mike myself.


If you get the bright white leather... just a word of advice. It does get dirty quick. We carry cleaner with us where ever we go... armor all makes it slick, so be careful. You come in off the boat wet and SLIPPPP!

It handles well... Ive notice that It can turn practically on a dime compared to our other boats. When we go out in groups, we always get a "man where can I get one of those."
On the ocean, we barely touch the water, mike loves going full throttle in tough chop. At one point, this year the nose was completly straight up and the prop was out of the water. I thought we were going to flip, but it handled it well. If I ever win the lottery, I htink Jillie wiill buy him a supercat and let him race. Thats his calling in life.

THe bottom is nicely crafted. Ive noticed that it has a smoother ride than many other boats, the over all design is a stream lined beauty. Its made for someone that wants to go fast and impress the ladies... Its a gorgeous boat that is reasonably priced.


We have the clarion stereo in ours. Theres so many speakers I lost count. I love the feature thatyou can be in the water and contol the stereo from the water.


ITs pretty good on gas... one whole day at full throttle is around 70.00.

and thats not even a full tank.


I will let mike know you want more details, and he will give you more specific information....

Enjoy!

Any other 252 owners. Wondering what speeds your getting with what HP. And what props are you using?

Thanks

Russ

I have a 252 with 330hp and a labbed 23p mirage plus prop. I gps at 64.8. I have a 502 short block I would like to put in it. What size cam and what compression ratio does a 500 efi have in it?

What RPM range are you running at?
I have a 6.2 in it now running 58 at 5000 RPM. The prop is a 19P, (to small) but I lived with it because I new I was swapping motors anyway.
My motor should be done in about 6 weeks hopefully.

I hope the 500 Horse Power will wake up the boat!

I run at 4600 rpm right now. Was at 4800 rpm before I had the prop labbed. I gained 6 mph with the lab job.What cam are you using and what is your compression ratio, also any head work done?

I have a friend with one. He is running a 25 pitch mirage plus labbed at about 65mph with 496 mag 375 HP.

boss252. Who labbed your prop to get you 6 mph?

Daron at Houston Propeller did it. He did an awsome job. I was running 58 on the stock prop before. I would recommend Daron to anyone. He will go out of his way to make sure it's done the way you want it.

I don't know exactly what Cam he is going to use. He is going to use the exact one that was used in the Hot Boat issue where Tyler Crocket modified the 502. I beleave the issue gives all the parts that where used for the project. In that issues they didn't do any head work.
Mine is having head work done. When Tyler dynoed the stock motor it made alittle over 390 hp. And after was around 490 hp.

So with the head work should give me atleast 500.

You can give Full Throttle Marine a call in Austin Tx.
1-830-693-5591 ask for Bob. His user name on this board is Bobl.

Ps. Does anyone have a soft copy of that artical anywhere???? Haven't read it for awhile.

Do you know what issue it was in. I may have it laying aorund somewhere.

I can't find mine. If I get time I might call Tyler and ask them what issue or call Hot Boat. Was a good artical. It used to be online at Arizona Marine but it's not there anymore. Unless I'm looking in the wrong place.
I thought the artical was about 2yrs old?

I'd like to have a copy of it if you happen to find it. I'll do some looking through my stacks to see if I have it.

I thinks this is it
