I don't see any benefit to going to the 350 on that hull. I also would NOT want the extra weight. I also wouldn't want the bill for the second prop when you need prop work done. If you ain't at all worried about needing the prop work done then you ain't pushing that hull like you should.....

 

If you’re going with that big heavy trp tank, might as well do the 350. They weigh the same because they are the same hardware, just a different tune. I would probably avoid both and go with a completely different outboard.

 

Negative. The 350 is over a 100 pounds heavier. Different deal.

 

I’d be curious if anybody has any performance/fuel burn numbers for the 250/300/350. It seems like on that type of hull I wouldn’t expect the same performance gains by increasing power that you might on other types of hulls.

 

A friend of mind has a 25 ft saber cat with the Suzuki 350 dual prop. I can ask what his njj in movers are

 

I went from 250 Suzuki to 300 Suzuki on my big battleship of a 26ft tunnel V and gained exactly zero mph. Similar but different from the Mowdy.

At the time there were no motors available and I couldn't wait. So I took whatever I could get....but I wish I had paid for a 250....

The props and prop work they have these days you can get all the hole shot you want without the dual prop setup.

 

It would seem that you’d get the most bang for your buck on that hull with a 250. It sounds like the bigger motors will likely get you minimal performance gains but cost you lots more cash and maybe weight.

 

both motors perform excellent, the cost difference between the 300 and 350 isn't really a big deal when you lump the entire boat together, Everyone that I know running the 350 absolutely loves them, efficient, quiet, they perform, and they look **** good, playing with props will be an expense, but it wouldn't be fun if it was cheap. ask Robbie what he thinks of running the over hub props on that hull.

 

That 350 TRP will weigh 727-775 pounds depending on the exact model and lower unit you get with it. It’s significantly heavier than the 300. But the zuke 300 is also significantly heavier than a SHO or Pro XS, roughly 640lbs vs 520lbs. I went with a 300 Pro XS bc of this.

 

There are 2 different Suzuki 300's . The dual prop 300 is identical to the 350 dual prop. If you are wanting the dual prop by all means get the 350. The single prop 300 is lighter & been around a little longer & most find it to be more reliable. If you do get the dual prop , skip the Suzuki props & go with aftermarket ones that allow the exhaust to exit on the outside if the hub like the original Yamaha TRP props did. They are made by Power Tech Props.

 

Some good points here. I have 3 Suzuki 350s I have a pair on a CH 31T and one on a boatright 25X. I did an extensive amount of research prior to pulling the trigger. The blocks between the 300 and 350 are the same. The 350 gets a bump in compression to 12:1 and I believe possibly a change in camshaft profile. Biggest deal here is running 87 89 octane vs 93. They are heavy and that’s something to factor for sure. In regards to that I would discuss with Mowdy and see how they think the hull will do with transom weight. There are lots of negative stuff on the web about the 350 unfortunately I think rolling out a new product during covid really was hard on them. Early they had some head gaskets and cracked heads and lower unit sealing issues. Supposedly been resolved in the more recent production motors. In my humble opinion I would probably go with the 300 dual prop.
I really like how the boat jumps up on plane very quickly. Also another thing that I love is maneuvering around the dock, getting on the trailer. Lots more reverse with 2 props… just saying. Everyone is gonna have an opinion something to be said for lightweight but in my situation my boatright is very heavy already. It probably weight almost 3-4 times what my 18ft shallow sport with 115 Yamaha weight and will get up a lot quicker.
Talk with Mowdy I’d trust their opinion.

 

What I rarely see talked about is range
I run a 250 that will push my not fast hull into the mid 50’s with very good hole shot. When underway it’s rare I run more than 35mph for any extended period of time, except a long run in Baffin. I care far more about range than stretching 55mph to 65mph… which wouldn’t happen on my hull with 600hp. Think about your normal cruising speed, look for some mpg numbers, and consider that as part of your purchase decision. As Grem pointed out, a 250 and maybe a 300 will most likely meet all your needs. Good luck with choice and enjoy the new sled. Exciting.

 

Might also consider RailBirds (Chuck McKinny) HPP double prop (HoleShot Performance Props)... it's not a TRP but 2 props keyed into each other by design. Can be run on Zuk using a Hub Kit (Merc to Zuke). I ran it. It does increase hole shot over a single prop and gets better fuel efficiency for increased range... Fuel savings of 6% ... not much but would increase range a good bit. Does drop top end 1-2% tho.

I'd go with the 300 and single prop or run chucks prop on it ... unless you have $ for if the lower goes out on the TRP

I’ve heard folks breaking prop shafts with this prop. Any truth to that rumor?

 

Thanks for all the info everyone. Definitely a lot to research on. From what I have found there isn't much difference between the two on weight and the few research trials done with the motors the 350 had the same fuel economy at 3500 rpms that the 300 did at 4200 rpms. I bought my first boat 20 years ago and was talked into buying the smaller motor for all kinds of reasons even though I wanted the biggest motor it would take . I regretted that decision for 20 years and just want to make the most informed decision. I can only find about a 100 pound difference between the single and dual prop. I am not one to gamble location when fishing and don't go where I don't know the water so lower unit issues could happen but I doubt it,

 

Just curious, if you aren’t going to be running shallow water, why go with the cat at all? 100 pounds may not seem like much weight difference but the location of it makes the effect much greater. If you put your fuel tank and batteries under the front deck, maybe it won’t have much effect but since that scenario isn’t possible, it’s going to squat that hull considerably. The flip side is that if it’ll float, it’ll jump.

 

If you are talking about Key Allegro, you may want to consider keeping your bay boat on a trailer and launch somewhere else like Conn Brown, Cover Harbor, or Goose Island depending upon where you want to fish. Its pretty tough to bust accross Aransas from KA exept on the rare light wind days to get to the fishable areas. Aransas is deep so the waves build high with the 15+ mph wind that prevails most of the time.

 

Bingo. Was much easier in the Corpus Condo and headed south. It's the only disadvantage of Key Allegro but it is what it is. Love the town.

 

Crossing Aransas Bay is why I have the two boats that I have lolol....had a house back on Canoe lake for 15 years....so coming out of Key Allegro.....crossing that big monster then into shallow stuff. Big 26ft Southshore Tunnel v and 21ft Lund Alaskan setup for shallow and duck hunting.

 

Aransas Bay is why I have the two boats that I have lolol....

LOL yeah my 22 Blue Wave sucks going across filled with water to many times. Expensive solution but happy to have a new boat.

 

Haynie Bigfoot is built for exactly that .... loved that boat on Aransas Bay. Ran it for years very happily. I just needed bigger when I was guiding more. If you aren't running shallow then look at the Magnum or HO. They run plenty shallow for most of that area.

Mowdy and Explorer would be distant second choice.

I wouldn't run a cat if you are crossing from Key Allegro. You will be limited on you days.

 

Yeah, i think i'd have a 25 Magnum if i had a place in Key Allegro. My Fat Cat handles water pretty good, but it don't want that bay some days, lol.

 

That fat cat is an animal in the chop. And likes a lil more speed in the chop.....hard to learn that... which will launch you! Lol

 

Yep, it's likes 55, not 25 in the waves, but man, that's one wild ride, lol.
