Drive Dyno...
 

Any one know of a shop with a drive dyno that can dyno one OFF the boat ?? I am working on a drive project and if I could test it on a dyno, it would be much better than trying it out on the water. It is a Bravo based drive.

Thx

I do not know of any marine shops that has a drive dyno specific only to use with it pulled completely. I do know Mercruiser has one that you use. Seen it and seen in use.

The dyno's that many marine shops use are from Land & Sea or International. These forms of dynos are to put a load on the engine mainly for after repairs has been made. They do hook up at the propshaft to simulate running conditions. I would maybe call Land & Sea to give you info of anyone that has one in your area as to what you are looking for.

Just some info

BUP Thanks but that won't work for what I am trying to figure out. I know the chances are slim to none, but you don't know til you ask right ??

My second option is to just hang a drive on a boat and go run it hard, not stupidly and see what goes first :)

I totally knew what you were talking about - I was just showing you what the marine dealers would have as what they use. Like I said Merc has one what you need but they are not going to share plus you would have to go to the state of WI for that.

You want to dyno a drive while it is off the boat? Cuz you are not dynoing the drive you are dynoing the engine...through the drive.

I think he wants to put the wood to it and see what breaks at what what level of power. Interesting. I'm curious now...

At a couple of the race shops I worked at , we had Dynos for Transmission and Rear Gears. They Had 50HP AC motors on the Input and Output Shafts. The cost about 250K a pop.
Used the motors working against each other for the load. Just basically used for run in of new R&P and bearings, and gear sets . Couldn't really Durability Test anything.
We used an actual race car and engine , on the Chassis Dyno to try and Break ****.

Don't know of them but found this under 'drivetrain dyno' search:

Also, Superflow makes trans dyno's. I would call them and see if they'll give you a list of places that have them and maybe able to test for you?
