velvet drive

guglielmo6160 · Post by **guglielmo6160** » Sat Jan 15, 2011 4:08 pm

the velvet drive that came with the semi projcect boat appears to be new or rebuilt, I installed it and it went in with not to many issues my main problem was to lift the back of the engine to make it clear to install the drive,
my question is , with the drive installed , I can move the rear flange with my hand, but,,, its rather stiff, not very easy to turn, but it does turn with no weird feeling, but just stiff, also when I crank the engine, just cranking by jumping the starter, it spins in the same direction counter clockwise no matter where I put the selector shaft, for neutral or reverse or foward,
I guess it needs actual engine speed to work? any info would help
thanks
Bill

Sounds normal . I Don't think cranking speed would build up enough pressure to engage the clutches , the slight spinning and drag when turning is due to normal clutch drag.

If for some reason it won't shift when running then the pump may have to be rotated

Not sure. Will it shift without the cable?

yes prowler, the cable is not yet attached as I am installing new cables and morse controls,
I thought the same about the clutches just like to hear it from somene else,
the main thing I was concerned about was how hard it was to spin the flange at the end, as I said I can do it with my hand and appears to be smooth but not like spinning a bearing at all,,lol
seems if I start the engine in neutral that prop is gonna move the boat this way,, hope not,,,lol
anway Ill use good lines, to hold her,,lol
thanks again, Im sure it will be ok

Don't forget to hook up the neutral saftey switch.
The engine should not crank at all if the selector is in forward or reverse.

Whats the history on the tranny?

You're saying

1)) it doesn't spin easily when a) not in gear and b) not connected to the engine?

OR

2) Or is it connected to the engine, and doesn't spin easily in Neutral?

He said" my question is , with the drive installed , I can move the rear flange with my hand, but....."

in gear or out would mave no difference as it takes the engine running to engage it in to gear (hydraulic pressure )

as I mentioned, it is installed , but not to the prop shaft, just to the back of the engine,
engine , not currently running, but cranking only via a starter motor,
I can spin the rear flange of the velvet drive, but not easily , but I can with my hand ,
when I crank the engine(crank only, ) the flange on the velvet drive spins only in one direction , irregardless of where I position the selector switch of the unit
hope that clears up my question, thanks
I believe all this to be normal

Normal

the only thing I was worried about was being able to move the flange easier by hand, seems it was easier to move before I installed it,,
just seemed strange, but the install went fine, so I figure its ok,
hope so,,lol

a lot more drag than you think. Does not feel like a wheel bearing/hub on car for example.

You could never get it to "spin" if that's what you were thinking. It'll only rotate with a strong hand.

You start to get a sense of how much horsepower it take to spin the shafts. Now add the friction from the stuffing box, the cutless bearing and most of all the prop going through the water.

yes thats exactly what it feels like, I can move it freely, but it takes effort to do so. Im sure it will be ok,
just never installed one,
my experience is limited to auto gearbox's which will spin free in neutral once attached to an engine,
this unit seems like its stiff, but from what Ive been hearing this is normal
