28sr twin 250xs motor's extended cockpit
 

so what's your thought on this package ?
reason for 250's instead of 300 is fuel 87 vs 91 octane, and on the water here i can only get 89 octane or 90 max no ethanol.
i wouldn't think much more then a 5 mph loss @ top end with the 250's vs the 300's and 99.9 % of my running is cruising between 40 and 60 mph anyway .
im thinking the twin 250xs motor's should put the top end somewhere in the mid 70mph mark " any thought's :

thank's

Call pep or jo they prob be able to give u exact # s

i was at the shop the other day and spoke with them ,
only one 28sr has been built and ran with a 525 efi and they got 78 mph without even tweaking the prop.
so i was guessing a little bit slower with twin 250's because of the extra drag .low to mid 70's would be fine for me .

Should be about right.

I like your thinking and your math.

Should make for a great package.

Don't forget about the few TS CC's that went to South America. Those were all OB's. Should give you a better baseline to work with.

Mike, Dustin’s boat ran 64 on Gps with a pair of old Evinrudes (I believe 200's or 225's Pepe or Joe can confirm) in the back and older style props. You should see that low 70's in a new boat with newer style props (technology has changed on props big time) and stepped bottom no dought. I believe that it's a great boat. Dustin's boat also had the extended cockpit and very comfortable.

that extended cockpit will be great for wife and daughter . and when there not around i can still have some fun with the boat in the ocean :)

other then the extended cockpit pro's and con's of both
single 525 efi
twin 250xs

You need to also consider an extended cockpit twin 6.2 Bravo 1.65 ratio setup with FWC. If I was building new I would go 14" extended cockpit with the single 600 and ITS 2" shorty sportmaster.
