Thanks for the reply Ryan, good stuff...which engine are you running.?
I don't have a dog in this fight but it's always fun to bench race. In the past Raylar did a ton of 496HO upgrades out here on the West Coast and lot of dyno work.
Here is a quote from Raylar that mentions the HP difference of the 496HO vs the 525. As mentioned, I've always heard the black motors are rated at the crank and blue motors are rated at the prop.
On the Mercury Racing HP500efi the engine really makes about 505-510 HP at the Crankshaft and about 470-480 at the prop with Bravo Drive losses.
The Mercury Racing 525efi makes about 550-560HP at the crankshaft and this results in about 525HP at the prop in a Bravo XR ( bigger drive losses in an XR)
Mercruiser 496HO's for example are measured at the prop they have shown to be about 390-400HP at the prop in a standard Bravo 1 or 1X drive.
Merc Racing HP ratings....?
Of course these numbers will vary on someone elses dyno, but they should be valid relative to each other. So if Raylar is correct, the 525 makes about 125-135 more at the prop than the 496HO.

Raylar is really close on those numbers. Dyno' s vary as well as HP numbers per engine. Some stronger than others. The 525efi is a MUCH stronger engine, powerwise/internally vs a 496HO. Not in the same league stock comparison.

This is kind of a big ask, but wondering if anyone with a VR1 or 290sc (and the standard AmeriTrail Tailer) could give me the overall length of the boat on the trailer.?
i.e. from the ball to the back of the drive in the trimmed up position
Thanks in advance if anyone takes the time.

My '05 290sc DOES have a Balsa core.. As stated before, depends a bit on the boating you do..
My wife does NOT swim so we needed a usable restroom also, the lake we're on is a bit rough for a "sit down" boat, so needed good stand up bolsters...
Between those items we chose a 290sc... We use the cabin several times a year and it's really comfortable for nocturnal activities...
Still a work in progress but runs 99 MPH thus far...

Pretty awesome numbers for a "sport cruiser"

Motuman you're in luck... my 290 is with me today. I just measured 32' 5" to be exact. That's from ball to longest leading edge of swim platform. I have my drive tucked in a bit so the prop is not past platform. Raining currently, batteries off and covered so no trim up measurements tonight,

I'm with you on that.
I take it one step further and tilt up and coat all bellows with 303 protectant, then store in down position. I've never lost a bellows yet and always replace preventively before they crack...bu they have lasted a LONG time with this method.

2004 velocity 260
Man that's haulin the mail! Shows how well these hulls take power.
Was 90 pmh a white knuckle experience? I keep reading that it takes a while to "get used" to driving a Velocity.( i.e keeping it up on the pad and letting it do its thing...with a few wheel flicks to straighten out any chine walk)
