How fast was the 28 with twin hp 500's in them? The carbed 500's 470 hp and real gps speeds. Anyone know?

I would say Tim would know best. he had that one for some time.

I would say low to mid 70s.

bigboat28 09-19-2014 05:04 PM

86 sounds sweet, but really?

bigboat28 09-19-2014 05:05 PM

I am thinking about trying to but a set of hp500s.

Craney 09-19-2014 05:40 PM

That's 86 on a trailer.

Really? I thought cherry bomb ran high 80s.
Funny, cause I run those speeds.

Wow 86 is good with 470 hp a side is great. Can't wait to get mine in the water I have 600+hp a side.
