Does anyone have any performance data on 2003 or so Gulfstream 232 with a 225 4 stroke yamaha? I have seen some posts that suggest a single engine for a 232 is a bit underpowered for that boat. I did look on Grady's website but couldn't find anything.

The 225F on a Gulfstream is not the ideal setup. It is okay with a light load and calm seas. If you running with 5 - 6 adults it can be tough in rough water to plane it out. It has a decent top end speed of about 36. Like everything there are trade offs and given the price of gas and where it is going a single engine may not be a bad choice. The 2008 models can be equiped with the 350. Mine is a 2004 and GW does not recommend a repower to the 350. Guess they must have reinforced the transom.
I have a 2005 Gulfstream with a F250. I cruise at 29 mph @ 4500 rpm 12 gph and wot 39 mph @ 5800 rpm 20 gph. The boat is a little under powered with a heavy load, but I'am happy with it for what I use it for. I mostly fish and cruise the Chesapeake bay.
I wouldn't do the 225 on a 232. People say the 250 is marginal and the 225 is a weak 225 more like a 210. You don't want to have to hammer the engine all the time.
nevsatII,
I've just purchased a 2005 232S, my first grady, which will go in the water in a couple of weeks. Can you share any tips for an absolute novice on this boat? Anything that will really help me get off to a good start?
We're avid fishermen but enjoy cruising the many rivers and inlets Midcoast Maine has to offer.
Thanks,
Larry

Larry: One tip on a 232: trim the engine up some when in reverse. Otherwise your propwash bounces off the transom and you don't move much.
232 w/ 250 hp
Purchsed a 2007 232 w/250 4 stoke last spring. Put 120+ hours before winter storage in December. She was a great boat and yes - slightly underpowered with full fuel, 5 people, etc. Suggest you practice docking, practice docking and practice docking. With a full enclosure you will find the wind can really affect close quaters manuvering. Then load her up and work the trim tabs and motor in various sea conditions and she will be just fine. I usually ran with on 1/2 fuel. And after a few hours you will think you are running a 30' Marlin - Which I traded up to and taking delivery on April 11!!

Ive got a 232 with the F225. It does what it needs to do; we dont run at WOT or want to run at 50 all day, so its no problem. I can feel it when we put 5+ people in the boat, but when theres 2 to 4 of us, its fine.
Weve never had an issue with getting up on plane (also haven't stuck 6 people in it when it gets rough enough to cause issues....that will cause other issues with any engine).
We cruise between 25 and 27kts, turning between 4400 and 4600. The dealer changed the prop around to help with the "under powering".... I have no clue what we ended up with.
Remember, they're the same block, and the majority of the same components. ones just been tricked out a little more to squeeze another 25 horses out of it.
The torque curves at the mid-range RPMs is most important; the 250 adds the VCT, which they say boosts the toque a good bit.
I would probably go with the 250 if I was to do it again, mainly for the mid-range get-up-and-go torque versus the "max power"... how many days do you get to run WOT anyways?

My 232 has twin 200 four-strokes, so I have no experience running a single powered rig.
I can say with certainty that a single 225 or 250 would have to work pretty hard under even normal operating conditions.
Thinking in terms of engine life and long-term durability, I wouldn't equip a 232 with a single. I believe it would be a recipe for premature wear-and-tear.

I contacted gw and received the attached performance data. I run with curtains and bottom paint which takes a couple mph off the top end but i have a large discrepancy in the cruising rpm's. At 4000 rpms i run 17 mph and 47 rpms i run at 25 mph, roughly. This summer i plan on trying other props to boost the performance numbers. Any prop suggestions would be welcome.

I also run quite a bit with full curtains, and bottom paint... We cruse between 25-27kts turning 4500-4600... Boats high and dry until at least 1 April, Ill try to dig up what prop we have on it.
I dont think I can quite stay on plane at 4000 rpm... usually have to keep it at a minimum of 4200.
Do you have the same prop as what the test boat had?

i do have the same prop as the test boat and definetely cannot get on plane at 4000. It sounds like we run the same numbers. This spring i am going to try a couple props to get more top end speed. We fish out of cape cod which is usually calm so top end is important for running around.
I've spoken with many many 232 owners that had the 2-stroke 250 and ALL have told me they wish they'd gone with the twin 150's. they all said once loaded with 4 guys and ice gear and everyfor a dys fishing the 250 didn't get up on plane as fast as they'd like. I don't see a 225 even comming close to doing the job even if it had a 4-blade prop.
Even though I have the older carb engines own my boat, I still can cruise about 24 and have a fuel consumption rate of about 14.5 - 15.4. I always troll on 1 engine rather then 2 when doing the Chesapeake unless sea conditions get rough then go to the 2nd engine for better response and handling. When trolling on 1 engine a 3knts, I'm only using 1.5 - 2 GPH. I looked at the 08 yesterday with that MASSIVE 350 on it and it probably SCREAMS when running a t WOT. I just don't know about trolling all day on a 350 when something smaller would use much less fuel. A kicker would run about another $3500 plus the added weight.
If I were to buy new, I would definately stick with the twin 150's.

As many have mentioned above, they cannot stay on plane below 4000K, ideally a boat should be able to get on plane before its ideal operating rpm, most outboards are between 3400-4000, being at the high end will not necessarily harm the engine, but yes sometimes these heavy boats do go through outboards quicker, but not always. What it does mean is when the seas get nasty you need to maintain a high rpm to stay on plane and cut seas, otherwise you will take a pounding, having some rpm to slow down and stay on plane is good. If you are climbing nasty seas, you want to be able to pull off the throttle and then punch it to stay on top of waves, if you are already running at a higher rpm, you have less power to punch it and stay on top. I'd say a 250 minimum, and ideally you want twins for that boat. Another alternative is a repower with a 300 Suzuki, many on here have done so and are pleased with it.
