'74 Aquasport 246 CCC outboard questions?(new pics 3/16)

[GoneFission]

That is a 24-6CCC - Center Console Cabin.  It's basically a FF with a console installed and controls moved to the console.  Aquasport did not make a lot of these - they are pretty rare.  

A 200 will push it along pretty well with top speed in the low 40s with the right prop.  The boat is rated for 280HP, so a 250 would not be a problem and a 275 or 300 would work well.  If I had a choice, I would go with twin 125s or 130s.  Twin 125 Optis would be a great setup on that boat and cost about the same as a single 250.

I know this thread is 2months old, but I'll chime in anyway...
I am very interested in your progress with this boat. I have the 246ccp model, just like yours minus the cabin. I have a 2002 yamaha ox 250.  I'll tell ya, the 250 on a bracket pushes the boat nice. Very quick hole shot. WOT with 1/4 tank fuel 2 people and Ttop was 47mph @5300 rpm.  I cruise at 4000 rpm between 30-33mph, pending on load and sea conditions. I have a stock S/S prop three blade.  Thinking of trying a 4 blade to get the bow down a little. The cabin probably rides great with that little extra weight in the front.  Keep the pics coming!

I haven't done too much with it yet besides move it to my new house. I hit something in my wellcraft nova and busted the outdrive so I've been getting that back in order. I hope to be able to get started stripping it and sanding it down next month to get it ready for re gel coating. I will post pics of my progress and I am thinking I'm most likely going with a single 250 on a bracket. I'd like to find a good deal on a mercury verado but we'll see how that goes.

Hi all
Fairly new to the page - I also just got my hands on a CCC and considering repower.

It has older twin 150 mariners currently. I’d love to stick with the twin power and reliability / range with twin Yamaha 150’s - but worry about the added weight. Based on some searches - these older mariners run about 400 pounds each where the 2018 yami 150 is 475 each.

Any thoughts / concerns or recommendations??

Thanks!!

The worry is the scuppers and even the transom dipping down.  An easy test is to load up 150 lbs of sandbags (SB) and put them in the bow of the boat.  Launch the boat and then while floating place 75 lbs of SB on top of each engine.  Stand at the helm and see how it handles it, then walk to the aft and see what happens.  Then it's your call.

Your old 150 Mariners are right at 425 lbs.  They published 405, but that was a short leg model.  And the Yamaha 4 cylinder 150/175 are 480 lbs. each.  The price of the Yammies is an OUCH!      

You might want to consider a pair of Mercury Pro XS 150-175.  These are fast, V-6., 2 stroke injected engines.  Weight is pretty close (430 lbs) and you can use the same controls and gauges (or switch to Smartgauge and keep the same controls).  You can get 2 of these for a little more than 1 Yamaha.  The Mercury 4 stroke 150 is another choice and you still use your old controls - it's 455 lbs each.   

Another option would be the Suzuki DF150-175 four cylinder 4 stroke motors.  These are about 470 lbs each - move the batteries up under the console and you should offset the stern weight.  Price is about right - more than the Mercs, but less than the Yammie. 

So set your priorities - wanna go fast with little maintenance?  Go with the Merc 2-strokes.  Want better fuel economy and not have to pay an arm and a couple legs?  Zukis might be the answer.  But check the prices for new controls/gauges too!  Only downside to Zuki is their limited service and parts system. 

Wanna spend some bucks?  Get the Yammies!  You will need new controls and gauges that are also pricey.  Also - you may want to look into the recent problems with Yamaha corrosion...
