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.

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.

I wish mine had a 525!! 496HO here. Do have an 80mm Raylar intake, Raylar 1.7 stainless rockers, Whipple Stage 2 tune. Boat runs great for what it is.

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... :)

Nice Velocity!

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,

Awesome, thank you! Looking at an online photo, it looks like the drive doesn't protrude very far beyond the platform in the full up position. (less than a foot)

Ryan00TJ - Thanks for the offer also.

Just FYI....storing with drive up is bad for the bellows.

Good advice Padraig! Especially in colder climates.

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.

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)

i just purchased a 2004 260 with a 496 mag I hear driving this boat is a little bit different and you have to learn to driv it what do you mean up on the pad and what’s recommendations for driving it?
