282 Sailfish repower

[Resolute]

Hi
I have a 2001 282 Sailfish powered with a pair of 200 Yamaha HPDI's. What are your thought with regards to repowering with a pair of 2008 f250's. I like the idea of the extra power but am concerned with the weight.
Thanks for your thoughts

The weight difference is 242 pounds. Get the engines and leave a fat guy at home when you go out.

No issue with weight, if you want to see how she'll sit it the water go sit on the motors when she's in the water, not saying you weigh 242 but my point is that i doubt the boat notices much. I have 2002 F225's on my 2002 Sailfish, I don't believe the weight is much different from those to the 08 F250's.

I have a 2001 with 05 f250s. She doesn't necessarily sit low but the port and starboard deckdrain scuppers are just at the water line. What kind of performance difference are you expecting with the f250s vs the hpdi?

 

[Resolute]

Thanks for the replies.
I guess if there was a fat guy sitting on the transom, I'd leave him behind...
With the HPDI's I get 19 gal/hour at 4200 RPM which pushes me at 32 MPH (28 knots). I don't really find those numbers terrible but I'm hoping to run at a lower RPM and get a cruise near 35mph. I really like the idea of not buying 2 stroke oil. Expense aside, it is just another thing to run out of... My 2001 Brochure shows a rating of 500hp but my Owners manual shows 450hp. No idea why the discrepancy. There are lots of boats similar to mine with 250s so I believe the transom can take the torque. The other variable is weight, seems like that should be okay too - but barely. I read somewhere that Grady raised the scupper height on later models to allow for the weight. I assume the floor height stayed the same though.

 

[mleads310]

Those numbers really aren't bad. If memory serves me correct my best numbers are around 3800-4100 35ish mph at 1.6 mpg. You're gain in cruise and rpm will be small. But there is a difference in plane time and power and obviously no oil filling to worry about. 2001 is rated for 450, but I checked with my insurance while shopping around for a policy and it wasn't a problem. You are correct in newer models of the 282 they raised the scupper height an inch or so (deck being same height) and I believe that's when they went to an all stainless steel thru Hull.

 

[ItalianAngler]

Mleads is on point, those numbers aren't too shabby. Takes a lot of running/gas/oil to recoup the cost of a repower. I can get to 30 statute mph at right around 37-3800 RPM depending on load, burn is usually 15-16 gph in a relatively modest sea state. It is bottom painted but very clean, lift kept. That is with my F225's with 2K hours. I find my 'F208's' are plenty powerful enough, it'll pop right up out of a sloppy sea no problem, never bogs, never wanting for power. At WOT trimmed out i've done 45 in the river, and honestly much more would be really spooky.

This is an email from Grady White confirming that the rating is in fact 500 hp and that the scuppers were raised. Great customer support even after 20 plus years.

Hello Warren,

Here’s the 2001 282 Sailfish brochure spec sheet that shows the max HP rating at 500. On most of our boats starting with our 2002’s we had to raise the hull scupper up 1 ¼” higher to help get these drain up and out of the waterline due to the heavier 4 stroke engines.

Older Grady White boats were designed for the lighter two stroke engines, we recommend simulating the additional weight of the four stroke engine(s), while the boat is at rest in the water, to see how the weight affects the waterline of the boat and the scupper locations. We also suggest having a qualified marine technician administer the installation of any engine repower. Your local Grady White dealer can also assist with engine repowering suggestions. I looked at our data base and I have an old performance test for the 282 Sailfish with Twin F-250’s for you to look at. Hope this is helpful.

Kind Regards,



Carolyn Ray

You might experience better fuel economy given the later tech and more horsepower . If the supply chain garbage wasn't happening I would say search for a pair of used 4.2 liter 250s. That motor shaves an additional 67 pounds off of the 3.3iter motors . So you would be over 130 pounds lighter with the 4.2s and then you can bring the fat guy too!

 

[mleads310]

Any chance you can email me the the f250 performance sheet. I thought I had it saved but can't find mine. All good points made above. And if you do go with 250s like smoky said the 4.2s will save you weight.

[mleads310]

Thank you

 

[Resolute]

You're welcome.
I can get a pair of 225 3.3 litre with 1000 hours or a pair of 4.2 litre 250's with 300 hours. The supply chain is giving me few options... Which way would you guys go?

 

[seasick]

What year are the 250s?

 

[Resolute]

2008

 

[mleads310]

What year are 225s? I only ask because 300 hrs in 14 years would worry me.

 

[Resolute]

The 225's are 2015

 

[mleads310]

I would go 225s only because high hour newer motors usually mean than were taken care of or they wouldn't hit the 1000hr mark. It's being used constantly which is better than 25 hrs per year for the 2008s. Again I don't think you need the repower, but if you're set on it, I'd rather have high hr newer motors.

 

[UCPA111]

Ahhh....just go for twin 300s. Verados would look good!

 

[Fishtales]

I had a 2002 Sailfish which was essentially the same boat with the Yam F225s on it. They were fine on the boat.
F225 and later when F250 came out are essentially the same motor. Weight was identical. I'd go without hesitation with F250s.
I have twin F250s on my Marlin and would replace them with the same motor in a heartbeat. These are well proven engines. I'll also look at the F300 and like you will jump for more HP unless there is a big cost advantage.
