Default Repower Mako 232/221b

Have a 1993 Mako 221b (later called the 232). Boat has a bracket from the factory. Has a carbed 200 on it. Transom is in good shape, no cracks anywhere.

Thinking about repowering with a new Suzuki 250.

Let's hear some opinions.. I know the 250 ox66 is fine on this boat and that comes in around 540lb..

New Suzuki dry weight looks like 580lb.

Let's talk boys!

A few folks over at classicmako.com have gone through this with that hull.

A few years back, I bought a 242 from a gentleman who bought it in 1993 off the floor of the Miami International Boat Show. That was the first year that mako put a bracket on the boat. The bracket was just added on to the the existing design that was already in place therefore, it rode stern heavy. There was always water in the cockpit from the live well on the floor. When I would accelerate to plane off, I would lose sight of the horizon at the bow for some time. This was with the original 200 horsepower Yamaha two strokes it had. Don't know if you have the same problem but I would be very weary of adding extra weight to the transom.

The suzuki 250 should be fine. I wouldn't go any heavier than that for sure.

Yes and I had to give it a lot to plane out.

Thanks for the replies guys. Ringleader, anything to substantiate that call?

Triplejs, thanks for your comments.

Your Mercury 200 is about 400 lbs. A Mercury 250 at that time that boat was made was about 450 lbs. A Yamaha 250 Ox66 is about 500 lbs. A Suzuki DF250 will be putting nearly 600 lbs on that bracket.

Do yourself a favor, if your Mercury is still running, put 200 lbs of sand bags or diving weights or something on that bracket near where the motor bolts on to approximate the extra weight and see how it sits and runs. I bet that the designers of that boat NEVER contemplated having a 600 lbs outboard sitting on that bracket.

It's not running good enough for us to take to the Bahamas. That's the goal here, to have a Bahamas capable boat. The closest point to us is only 50 miles but I'd like to update my power, the carbed 200 yamaha is tired.

I agree that the four strokes are much heavier... I was just seeing if someone had personal experience.

I guess I could look at etecs, they are much lighter. Guys seem to either hate them or love them. Btw I thought the ox66 250 was closer to 540lbs?

As much as I love my Zuke on my 23 Regulator, in your case you may indeed need to be looking at a E Tec. Unlike your boat, my year/model was built at the time of introduction of 4 strokes. Do yourself a favor, get the lightest outboard you can so she will not only sit right, but run right as well.

Buddy has the 232 it's a nice ride. I'm often at the wheel and know the feel for that boat. Great ride for a 23. He had the saltwater yami then after that went he repower end with a 250etech. I think he was hesitant to go with any of the 4 strokes because of the weight. Like the above comment the boat def needs some tabs to get on plain the most economical way. The 4stroke may be just a little to heavy for that boat and bracket.

I think his cruise numbers were comfortable around 30mph at I think low 4000s ....wot was between 41 and 44 depends on weight if I remember correctly

Great input.

Opt and etec are looking at costing 22k... new zuke 250 18.5K

I'm doing some more research as to whether the hull can handle the four stroke.. I know resale is never the end game in boats... but, I like not burning oil (hear the opt oil is expensive), and a few years from now.. I can imagine people REALLY not wanting two strokes.

My feelings of the weight are based on a few 224's that were restored and bracketed with twin outboards. Both had 115's or something like that and it was entirely too much weight. Scale back to a single 250 or in the case of my old Mako 21 that I closed the transom in on, the new owner put a bracket and Yamaha 300 on the boat and it performs beautifully. I drove the boat myself a few years ago in Destin and all of its characteristics were very good. So as I said before I'd try to keep the weight as close to or under 550 lbs.

Excessive bow rise on planing could be a motor height and/or propping issue as well. My 261 had more bow rise with the OEM carbed yamaha 200s and yamaha props than it does now with 225 Optimaxs and Merc tempest and bravo props I swap back and forth.. The motor height I have set to since the restoration might have something to do with that.

Etec or Optimax would be good choices as far as I'm concerned. The Suzuki 250 and Yamaha 250/300 also doable. Personally my dilemma is that I'd love to put 4 strokes on my 261 Mako, but I sure don't want to go down in HP and I certainly don't want to go up in weight. So until somebody makes a 225 HP 4 stroker that weights less than 520lbs, I'm sticking with Optimaxs and oil tanks.

My friend went from a 225 Yami saltwater series 2 stroke to a 300 zuke 4s on a 23 mako. Way too heavy. I built him a floatation bracket 88 inches wide, 36 inches out and 20 inches deep solved the problem.

We were at this crossroad with our 97 21 Contender (had a 200 Yamaha), as much as I would have liked to put a 250 yamaha or suzi, like you I was afraid the weight would have been an issue. We ended up going with the etec and couldn't be happier.

Have you considered maybe the Yamaha I4 200 4stroke?

That would be a 35 mph boat with a 200.

OP, I just put a 300 on my SeaCraft. Power is great. 52+ top end but cruise is unreal.
Like 38 mph still getting over 2.5 mpg. 3.6 mpg at 28.

Anyhow, I had 2002 115 Suzukis for over 13 years. First on transom, then on bracket.
Did I get wet feet sometimes? Yes. Was it stern heavy, a little. Performance was fine even
with 850 lbs on the back.

My new 300 sits the boat about 1" better in the waterline.
I'd say go for a 250 or 300. 50-60 lbs isn't going to make any difference and if it does,
rearrange some weight around to offset

One member at classicseacraft had a stern heavy 20 ft with a bracket.
He ended up making a small foam filled fiberglass rectangular "box"
He mounted under his bracket for added flotation.
Painted it up. It looked great and gave him the little extra flotation he needed.
