240 Sport Info.
Hello everyone,
I just purchased a 1988 240 Sport. The boat has a new crate 502 (I’m still trying to get more info on the motor) and is relatively stock. The boat is in great shape for a 1988 but I do plan on some upgrades and modifications. If anyone has up graded or knows of problem areas to look out for please share. Thanks in advance for any info on the 240. Speed |
Re: 240 Sport Info.
change your cam and springs,lifters and go to hdy roller set up crane 731 cam which is about 600lift cam l,center about 112 or 114, s/m headers or c/m 830 marine nickerson carb, msd so lets see headers about $2000. top end cam set up carb intake merlin about $2050 you should get 550to 580 hp and tq 560 and go from 64mph to 78 mph. ps I have a isky cam, but I hear a lot of peaple use the 731 I believe I DID THE BOTTOM END TO MADE IT A 510 647HP 627TQ

Re: 240 Sport Info.
I have a 1989 240 Sport with a stock 365 Mag it came from factory with K planes Zero Effort throttles a real nice rig . I just did a major rework on the floor rear seat and engine comp. I cut the seat so you can remove the rear portion in order to work on engine easier, But it still appears stock Pm me if you would like to talk , I have much insight and don,t mind talking ,a great boat Just had to do some refinements

Great gob on the dash and motor! :drink: I hope to start on the interior this winter. Did you use the stock dash panels or did you make new ones? Codered I will catch up with you after the boating season and I have the boat here so I can tinker with it. What you have done with the back seat sounds cool. :drink: I hope to do some engine mods but that will be in the future. need to replenish some funds after purchasing the boat. Thanks for all the info. and pics. I’m starting on the dash first this winter. Thinking Zero effort controls. New gauges, cup holders, seats need a little attention, floor and carpet are new. May install some kind of trim tabs, need a little more seat time Has anyone put a foot rest in or on the floor? Thanks again. Speed |
Re: 240 Sport Info.
One problem area to look for is the plywood to rot in the sunpad/engine hatch. I had to replace mine a couple years back and put in marine ply. Other than that mines been really good and still turns the heads. Pushing 500 hours on the factory motor.

Re: 240 Sport Info.
On mine I said once before MROUTBOARDV8, JEB, AND I TOOK A SHEET OF DECOLITE CUT IN A PRO STOCK SCOOP AND GOT RID OF THE LINER AND CRAP ITS LIKE 15LBS AND YOU CAN JUMP ON IT. JUST LOOK AT MY PICS. AND WE MADE IT IN 1996 :p I AM MAKING A PERMENET REAR AND FRONT BULKHEAD ONE GOING INTO THE CABIN AND ONE WERE THE BACK SEAT WAS .THE SCREWS AND BOLTS FOR THE BACK SEAT HAVE MADE A MESS OUT OF MY BOAT. WITH 650HP GOING TO 700hp OR SO THIS WINTER I might give up ON THE baja and get a blank hull from sutphen,superboat,or joker depends on how the cash flow looks, If that happens I will strip it all the perforance stuff has low hours on it ,the last race I was in was 2002 :( so we will see. On mine it was never left in the water and there was delam in the floors bulkheads :mad: TRASOM LOOKS GOOD ,BUT IT MIGHT BE TIME TO PUT HER OUT TO DRY.

Re: 240 Sport Info.
Anyone suggest a prop? 3 blade or 4 blade, manufacture, etc.
Boat has a 502 (I believe it is close to stock) Thanks Speed :D |
Re: 240 Sport Info.
when I had the stock 502 I ran a 25p m 3blade at 48rpm nice also still have a turbo 24 ran 5000rpm nice shape $200 a little quicker than the 25
|
Re: 240 Sport Info.
that was 4800rpm :rolleyes:

Re: 240 Sport Info.
Just got home from the lake. Boat ran well but liked to porpoise. Could not trim the motor up much without blowing the prop out.
the only prop I have tried is a prop from the local marina that Im looking at purchasing. The prop is an Apollo 14” x 22p not really impressed with the Apollo Trying a 3 blade next weekend. Air Time, Is the turbo a 4 blade? Thanks Speed |
Re: 240 Sport Info.
It's a hydromotive and its a 3 blade with a stock drive height the 3 blades seem to run better, but I heard the merc rev 4 in a 23p which is a 4 blade runs good on these boats or a 25P that is labbed BBLADES CAN HOOK YOU UP ON A NEW ONE, hope this helps. never heard of APOLLO :eek:
|
Re: 240 Sport Info.
Hi Air Time,
you like the 3 blades better than the 4??? I though 4 blades would make the boat run better all around but the 3 blades are a little faster on top end. have you tried both 3 and 4 blades on this boat? another question, wind screen - my boat has the windshield and it does nothing to cut the wind. can the boat be changed to a windscreen what would help cutdown on the wind in your face. or have you seen anything that would help. don't get me wrong, wind in your face is cool for the first hour or so but by the end of the weekend it can get old. Speed |
Re: 240 Sport Info.
Now that I have the shortie drive I need a 4 or 5 blade. The wind think, my faring is shorter than my windshield was I think trick might have some flaps that flip up when you go fast which will help. ME I like my checks flapping in the wind :D :p

Re: 240 Sport Info.
hi speedboatr
i have a 89 240 sport that i got from my uncle and he made air deflecters out of plexyglass and on top of the windsheld. i can put them on and off in seconds it looks ok but they work great and like i said they are real easy to put on and off. if you would like i can can talk to him and ask all what he did and i could get pics for you to show you what it looks like |

Pics and any info on the wind deflector would be great! :drink:
What motor and prop are you running? Just curious? Here is a Pic of my 240 Thanks, Speed |

Re: 240 Sport Info.
Is that just suction cups holding them on? Any problems with them coming off? that is an easy way to help the wind problem :D
Speed |
Re: 240 Sport Info.
nope,
3" suction cups from true value and some of those adhesive bumpers you stick to drawers and what not to absorb bumps |
