Gulfstream

[Flanny1244]

Maybe buying a Gulfstream soon. Looking to reposer it w a Suzuki 250 or 300. Any thoughts on HP and what size shaft would I be looking for?

250 may be underpowered if single motor. It's a 'big' small boat

Would a 300 be better? That may be Max I can do financially

My 2004 came with a Yamaha 225 four stroke and runs great, not a speed demon but is enough HP with a full crew with gear.

Go as big as you can afford.

As a frame of reference, I am running a 300 Verado on a 22' Seafarer. I second the idea of "go as big as you can afford."

Jeez, 300 minimum. HEAVY boat, weights more than a Grady 248. My 2 friends with with Gulfstreams have a Suzuki 350 with Dual prop, other has twin F200s.

On the Suzuki’s I believe the 300 is the exact same as the 250 except for the ecu so you’re only gaining a little at WOT. The Gulfstream is inherently not as “fast” as other Gradys due to the aspect ratio of the hull so don’t expect it to be a speed demon regardless of how much power you put on. Spend some time getting the motor height and prop dialed in and you’ll be good for the majority of your use.

That said, no one ever complains about too much power when sh*t hits the fan...

If it is a single, go with the 300 HP. Mine has twin 175's and they handle the boat with a big load very well. Jumps on plane and gets up to 2.1 mpg at 30 mph. I would think a single 300 HP would be very close to my setup.

Hull is rated at 400hp. Most came with either twin 150/200s or single 300. I'm with Bird on this one.

I've got twin 150's on mine and would not want anything less. I'm just reinforcing what everyone has already said.

I have the Gulfstream 232 2017 with a 300HP Yamaha. I would not put anything smaller on it. The 300 HP will be enough power to get you on plane quickly and move the boat well. The boat would be best with twins 150s or 200s but it will cost more for maintenance. Twins are easier for docking but the 300 HP is a great option. Good Luck.

A couple random things, in no particular order, I have learned over the years...

-- The most important thing is whether or not the engine provides the performance YOU want, not someone else's opinion.
-- No one will EVER say they would be happy with a smaller engine than what they currently have.
-- No one in the history of boating has ever said "I should have gotten the smaller engine".
-- It's never a bad thing to have a bigger engine.
-- What is "needed" for one person does not dictate what is needed for someone else.
-- See my first "tip".

That said, my opinion... a 250HP is not "underpowered", but it may not be "enough" power... again, depending on how YOU will use it.

Agree with Dennis as well. Really comes down to affordability and use case. I'd do twin 200s but if I was going single, I'd do the 300 for my case and resale.

Right now, Gulfstreams are scarce as are lots of boats. That said, I see that 232's with single 300 are listed for sale longer that those with twin 150s. Twin 200s sell really fast.
Personally having both a boat with a single motor and one with twins and taking into account the slips I have had both boats docked at ( 4 different slips, in different dock configurations and direction with respect to typical currents and winds), I wouldn't opt for a single motor on a hull like the 232. So fo me, a single would affect value a lot

That boat is wide. I would go with a set of twin 150s. That is a balanced choice between cost, operability, and resale. Plus you won’t regret it. I have seen so many people under power boats and as they get more confident with the use and take bigger trips they begin to see the limitations. ****Here is an important question, which bracket is on the boat? A bracket for a single or twin? If it a single, go with a 300 or better 350 and run her light. That would be an pretty good option. That boat dry is 4500 lbs. that’s a big boat for any single.

I had a 300 Suzuki on my '95 Gulfstream. Perfect motor for the boat. That boat got destroyed in a tornedo last year. Found a nice '05 Gulfstream with a 225 4-stoke Yamaha. Miss my 300 Suzuki, but like the newer boat.

 

[Cape232]

I repowered a 2001 Gulfstream in Summer 2019 with a 300hp Suzuki. I replaced a 250 Yamaha OX66. I have been very happy. Would twins be better on a Gulfstream, yeah probably but my bracket was set up for a single. I think the price to change over would been pretty crazy.
