24' with twin small blocks
 

a friend of mine has a 87 24' sport with twin 350's in, I never seen one like this before. Has anyone else seen this combo before?

No, never even heard of one that small with twins. Any pics?

I don't but he must! I'll see what I can do to get some on.

I'd like to see some pics, also. Never heard of twins in a 24. Custom retro-fit, maybe?

That's a long time ago, but I think I remember one that was built in production at Baja. If I recall the handling was terrible! There were also twin O/B versions built.

I have seen twin 265's before. Never seen a 24.

The 1987 Sport 240 twin outboard that was rigged here in VA also handled terrible. :confused: Twin 250 HP Mariners that would chine walk you out of the boat. My single blown 572 BBC Sport 240 handled OK on smooth water at 91. But ate bravos for lunch on any given day.

I forget what centers were used on twin O/B's but I bet they are fighting to stay down in the water at top speed. The 240 has just too short of a running surface for twins. Twin IO's would be a CG issue with too much weight in the rear in that hull. It is best suited for one BB engine only IMO. The 265 was a great running twin SB Baja though.

Yup, I have one!:thankyouthankyou:

I AGREE!!:Score-101010:

this one was done at the factory! as far as handling I've only riden in it, never driven it. seem to ride ok though. just been curious as to how many there actually are. he thinks that 5 were built.

never seen 2small blocks in a 240 i race a guy that had a 300outboad did 57mph look like it handle ok.

That's about where this one is at

Does anyone have pics of the outboard version of the 24 sport?

What kind of speed are you guys seeing with your 265's with the twin 350 mag's? I have always liked the idea of a twin small block setup on a boat. Gies you a little more room to work between the engines, and parts are cheaper than for twin big blocks. A pair of good running 383's with Bravos to back them up would be golden, IMO.

When I was boat shopping 12 or so years ago, I am pretty sure that I saw someone in the northeast selling an '87 Force 235 with twin small blocks. I wonder if it would have the same handling issues as the 240?

I've never had mine set up for speed.

When the boat was new, it came with 23 degree props.

I got it with a set of 20 degrees. I've kept it this way because we do a lot of tubing.

Tha being said, I've turned these engines at 5400 rpm on occasion, hitting 70 on the wishometer. Running next to a buddy's boat, his speedo had us at 63.

Last year, with 4 adults, 4 kids, full tank, the wife's cell phone gps had us at 56.

The engines are stamped max wot rpm as 4200-4600. I would like to turn them at about 4800 if I ever set it up for speed, so it's a guess what the boat would do with the 23s.

Mid - upper 60's?

I might have to see if I could borrow a couple of right hand 23s and find out once and for all.

Wouldn't you want a LH and RH, or do you have one CR Alpha on it?

This is 1987 technology. Quite common to have both standard rotation drives in this vintage.

For the record, Ken, the prop pitch is measured in inches, not degrees. If it had theoretically zero slip, a 23" prop would propel the boat forward 23 inches with each rotation. Doesn't really have anything to do with the angle of the blades. To further confuse thing, some props have more "cup" in the blades, which actually contributes to bow lift and makes them act somewhat like a bigger prop.

You understood the message, right?

Yes I did. Sorry if it sounded like I was belaboring the point. :drink:

It's all good. Many times, the problem with the written word is that we can't see body language or hear voice influctions.

It sure would be neat to see some pictures of this boat.
