Thanks

PS. - 100 hour check ups @ $550 = $5.50 per hour to add to fuel burn rate.

I've not heard too many good things about the 4 cylinder 200 hp Yamaha. The problem I hear is it seems to be a bit wimpy. I don't have one on my boat to properly answer your question, however using my boat as an example with 140 gals of gas, full load of ice, beer, drinks, etc., plus people that engine ain't gonna cut it. The 4.2 V-6 225 -250 hp is a different story. Good luck.

one of my friends did put a new 4 cyl 200 hp yami on an older 23, and said it is a great combo.. top speed at 35 mph, I do not know the cruising specs.I think it works.I did a repower on a 96 26 regulator with a pair of these ,and they were perfect,great midrange power and top end...awesome motor !

That's much slower than I would have expected.

200 Yamaha
 

Well Terry I'm not a English teacher, I'm a fishing guide. Those numbers don't sound right. I have a 2015 Tidewater 24 Baymax with a 200 and at 4000 rpm I get 30 mph and 4 mpg. Not sure what your dealeres are telling you but I did not pay $500.00 for a 100 hour service.

For what it's worth. My buddy runs a merc verado 200 on his century 24.5 with ttop 50 gals fuel. Ant at wot hits 46 mph.. At 4500 runs36 and burns about 10 gph...this is with two old fat beer drinking fellas..I would say it is pretty doable...unless you want to run 50 mph.
..FYI we did run a 250 verado on this boat and it hit 56 mph.. Way to fast but it was nice to have to power when needed

BTW. Nice Bear Todd

Capttodd- take a look at the threat I started under photos, peanut island. I have a 77' 23 with a 200 Yamaha HPDI. Bushwacker made a great comment and there are a few pics.

Here was the info you asked for:

Per the post: When I bought the boat I thought with only a 200 it would be a dog. Far from it. A good crusing speed is 3600-3700 rpms. Boat is running about 22 kts while burning no fuel. Even with the top, yetis, fishing gear and 4 people, boat still gets up and goes. I would guess about 40mph wide open, 5500rpms medium load. Ran from the Boca Inlet to Palm Beach Inlet and back with 4 people and all the wife's BS, burned about 20-25 gallons all day. Boat holds 100 gallons.

Thanks for the info Snafu. I think I will go with the 200. I will post the info on it as soon as I get it.

Here's my 1987 175hp Merc Powerhead pushing my 23 WOT.

I bet you get closer to 45mph with the 200 yamaha

After having 2 different 200 hp on our Sceptre for a period of 8 years, I would predict around 37-38 mph at WOT. No way mid forties.

Bigshrimpin must be running nitrous O2....LOL!

A brilliant deduction! I'm gald we could help with your data mining and analysis. The gray motors are good ones - I'm sure you will be very happy with your decision. Glad we could help you get they'er.

That's funny Terry!!! I hated English class in high school, especially my senior year when the teacher's got more serious about my grades and less entertained with my goofing off, I really did not want to be their. :)

Nice Don, I caught that!

You did not help with squat...it's people like you that keep most people like me off of forums. If you have nothing good to contribute say nothing.

Yikes....thin skin!!! We're just having fun. You are welcome to move to THT any time.

This place is a little different than those other sites. It's more of small town where all the people know everyone and they're business. You'll get a kick out of gofastsandman and spidercrab. Don't give up on it just yet...

Sorry, I just don't think an inline 4 cylinder is going to perform in real world conditions at any satisfactory level. 200 hp is pretty marginal for ponies on an offshore hull rated for 500 hp. Maybe a bay boat it is fine but you have to think about the torque needed to hold plane in seas and the overall requirements for load on a day offshore. Would it work... sure but it isn't going to be impressive at the least.

I get about 37-38 mph with my f225. I was wondering about the 200. I had a 225 ox 66 and it was faster than what I have now, but I couldn't wait to get it off the boat. My f225 isn't fast, but it gets me there. It's almost 11 years old now.
I think some folks are comparing apples and oranges here, 3700 rpms would maybe get me on a plane.

Grammar challanged!
 

Put your dang trowel down, git outta' them mud boots and bring the "Little Red Rooster" to Homosassa, Bud! You'er waist'in yur life away trying to cover Charlotte County with concrete, son. Greed will git ya'!

Mr. Bushwacker, Mr. Bushwacker, oh.....Mr. Bushwacker,
72potter20 is making fun of me again.
Gee Willikers, don't he know I is a product of da' Pinellas County School System!
So their.....or they'er......or I mean there.

72potter20, have you ever been to one of those NOAA Marine Fisheries "Public Outreach" meetings where 576 people get up and say "your new program stinks and 4 say we love it"? Then they vote with the four, because that's what Roy Crabtree wanted them to do anyway, but they had their "Public Hearing" so there is an appearance "of process", although it was meaningless.
Well occasionally someone will ask something on this forum like "Is anyone running one of those 225 flat 6 opposed, turbocharged, intercooled two stroke diesel, jet drive C- Kings, I'm JUST THINKING about putting one on the back of my 18"? Then 39 members chime in with all the many reasons the C-King would make a better anchor than aquatic drive system. A week or two later, after stirring up a hornets nest emulsion of mechanical engineering, thermo dynamics, and propellor disc surface theory, it is pronounced that "I went with the C-King and it is awesome!". Well maybe he wanted a C-King all along, but wanted to have an "appearance of process" by which he could report that "I ckecked with the Guys on the Classic Seacraft Site and they were like thumbs up".
Everybody builds pretty good motors these days, pick a color, bolt it on and go fishing - you'll be fine. Of course I'd get a lifetime membership in Sea Tow, if I got the C-King!
Now I'll go back down on the bottom of this forum where I belong and sulk.

You're forgiven.

Could be worse......a product of the Hillsborough County School system....:(

I might show up.
This has been my best year since 05. It's not greed; it's going for 4 years with nothing but little sidewalks and a.c. pads that I practically had to give away...
I did cancel today's pour because of the rain that's still sitting out in the gulf.

I need to finish this cycle and go through at least one more of the "good times" before I can relax a little.

There is nothing worse then common core in school.. Ebonics would have made more sense,, just saying

1. Max HP on a 23' cc was 400 hp.
2. I fish hardcore in South Florida and run to the Bahamas. Never has my boat been a dog even fully loaded with 100 gallons on board.

LOL!!!!

3700 rpms I'm running mid twenties!! Can't get off plane, COME ON! Get a new mechanic.

Word!!!!!

Let me splane. I assume that the op was talking about getting a new 200 four stroke. You say you have a hpdi(2 stroke?). One of the first things I noticed when I went from the 225 2 stroke to 4 stroke was that they were geared different. The four stroke was turning more rpms for the same cruising speed.
The problem was, at wot the four stroke would only turn about 5300 rpms with a light load. As I understand it, the four should turn 5500-6000 with full load. I elected to go with a four blade 15" pitch that got me about 6100 with light load. It does seem a little under propped, but I would rather it turn a little free. Its got nothing to do with the mechanic.

Let me explain. First off the motor could have been losing carboration in one of the cylinders or a number of other mechanic issues. I will agree that the prop is the key to the equation. If someone were to ever tell their mechanic there boat was not planing at 3700 rpms, I hope that would be the first recommendation. But we're getting away from the topic.

No question you get more out of the hole with a two stroke vs a four stroke. I have a 2006 HPDI. Given my personal experience, you will get a boat that performs well (when proped correctly), no planning issues, is extremely fuel efficient and will get the job done.

Now if you want to enclose the transom and add a bracket, a 200 would be light.

And that is what is probably going to happen.enclosed transom and dual engine bracket.. Come to think about putting a single ,On a dual bracket , I believe you need a 30" shaft motor.. Yes, no??? My theory is it's.better to have more engine than not enough... But that just me... I like 2 strokes..

I want one of those motors that uses no fuel at 22kts. Guessing at 20-25 gallons fuel in a day is a wide spread. Actually, I can agree with your "guess" at 40 mph wot. My test was with little current or wind and checking my speed with two people, no gear and light load of fuel, I got 34 knots on the gps. Do the math, it works out to 39.126 mph. Real world estimating with more fuel, gear etc, I said 37-38 mph. Is that much different from your guess at 40.
I said that I may be a little under propped, but I was told long ago that having a motor spin more free will have it live longer. I would rather not have too much prop, which was the case with my 3blade 15-17.
If you notice, the wot is not much different than your motor. My four stroke lacks the torque at low end. I think that is why they changed the gear ratio to make up for it.
I'm still not sure what engine the op is buying. If he is buying a new inline 4 cylinder (2.8 liter), what does that have to do with your engine, hardcore.

I owned the same f225 on my 21 Paramount. I thought it would work out well but the first gen 225 were identical to the 200 except for the cowl sticker and price. At the time Yamaha utilized the industry fudge factor to pass a motor rated at 205 hp as either version of the f series. As far as the 200 hdpi goes.... It is over 100 lbs lighter than the F225 of that era and tested at the prop to 215 hp. I will also say the 200 hdpi was one if not the best hdpi of the series and absolutely apples and oranges compared to the f225.

Lol! Your hilarious, do you own a 23' with a 200? Don't be ignorant, my estimates are based on actual usage and OWNING the boat. A 5% delta?! Again, stop being an idiot.

A Paramount is a completely different hull design. I actually had a 21 Concept with a 200 Ocean Runner and the boat ran well but was not a speed demon. 200 HPDI is a great motor.

Here is a pretty fair comparison of the f150 vs the i4 f200. Not a whole lot of difference for adding 50 hp. Do you think the comparison would remain as relative when going from a 200 4 cyl to a 250 V6? I doubt it.

Agreed. My point is only to illustrate what is on the sticker is not what is always under the hood. Not all 200s are created equal by any stretch of the imagination.

From the test I posted above it appears the i4 f200 is another Yamaha ploy to sell with the sticker. That is why I feel the i4 f200 the OP is questioning is not enough motor for a 23 SC. The torque curve of a 4 stroke 4 cylinder is of no comparison to a direct injected V6 that is rated above it's cowl sticker... and torque is what a 23 foot offshore, deep V boat requires.... not a "200" hp 4 cyl motor that is at best marginally peppier than a 150 on the same boat and identical at cruise speed.

I agree. I don't think a light duty I-4, 4 stroke Yamaha 200hp is enough motor for the 23. Too weak and pretty heavy too (Compared to a 2 stroke)
