Hello all,
I know more power is always better but is new twin Yamaha 150's sufficient for the mini bertha a 2006 gulfstream 232 for repower? I can't source the 200's and the cost is way more anyway! I have a chance to slap a set of new twin 150's on it now for repower!!

Plan to use her for playing in the pacific ocean with an average of 4 adults chasing halibut, salmon, bottom fish and occasional tuna!

Thanks

Chris

Brand new 232 in the showroom at my local dealer, outfitted with 150's. That should tell you something.

Yes, it tells you the dealer cant get 200s either:)

Did you notice if the motors were digital throttle and shift?

Per the Grady White website, a brand new GW 232 Gulfstream with twin Yamaha 150's on it will top out at 48.4 mph @ 6,000 rpm and burn around 32 gph while doing so. Optimum cruise is 29.2 mph @ 4,000 rpm and only burning 13.3 gph. How much faster do you really need to go then almost 50 mph on the water? Especially with fuel prices being considerably over $5 per gallon at multiple locations throughout the country? lol

Comparatively, a brand new GW 232 Gulfstream with twin Yamaha 200's on it will top out at less than 4 mph more, at 52 mph also @ 6,000 rpm and burn 40.5 gph while doing so. Optimum cruise is slightly better at 29.8 mph @ 3,800 and only burning 12.7 gph. I'm definitely of the opinion that the considerable amount of extra money needed is not worth going 52 mph vs just over 48 mph, especially with how much fuel you're burning at those speeds. My boat tops out at around 45 mph and I can say that's definitely fast enough for me on the water.

Perfect, heck not many days in the Pacific you can even reach 30mph!! So then this is a go!! I didn't even think to refer to Grady's website instead came straight to here!!

Thanks!

Yes, yes, and yes. We owned an ‘05 Gulfstream with Yamaha F150s for 10+ years and they are a perfect match for the boat. Feel free to reach out with any questions.
Good Luck.

200's are better than 150's for the 232. I had one for 10 years with F200 V6's and consistently got 2.0 to 2.1 MPG with bottom paint. I cruised at 30-34 MPH and had plenty of power when she was loaded with friends.

The new 200 I-4's will likely not have the low range torque for planing and sawing thru rough water than the older V6's, so 150's would be a sensible option between these two.

150's will do the job fine. Either power option is better than a single for a Gulfstream.

I rarely do much over 35 mph or so in the Puget Sound because I want to be able to slow down, stop or deviate course if there was a deadhead, log or something else just barely floating on the surface of the water. That and as mentioned above, I couldn't imagine blowing through over 40 gph at $5-$6+ per gallon of fuel. I'd rather go 30 mph or so and burn less than half the amount of fuel per hour than going top speed.

Just repowered my 2000 gulfstream with twin 200 Suzuki's . I had twin honda 130s. Boat was reliable for 20 years but underpowered when 4 guys onboard. Feels like a rocketship out of the hole now. The 150s are the standard but the 200s are really nice.

I have a pair of 150's on my 2007. Sure I would take the 200's if they were sitting there, but I'm not sure I would pay a huge premium to have them. The 150's have been a great match for the boat and I have never felt underpowered - even with 4 or 5 guys on board.

I also have a Honda 2005 engine, I need to do maintenance, I'm trying to calculate the cost to go fishing, I hope it won't cost much.

I had a single Honda 130 hp 4 stroke outboard on my 21' Arima before buying my Grady White and while that amount of power was suitable for that boat, they are definitely heavier than average motors. The dry weight of a Honda 130 is either 496 lbs or 505 lbs depending on the shaft length, which is almost identical to what the Suzuki 150 and even 200 outboards are at a max of 531 lbs. So, your new motors essentially being 25 lbs more per motor than the Honda's but also having 140 more horsepower with twin 200's, or even 40 more horsepower with the twin 150's... it's going to make a huge difference in performance.

I have twin f150 2019 on my 268. Works out perfectly. You will be in good shape. Choose the props wisely
