Default Flexplate Vs. Flywheel......and a stupid question?

Maybe I have assumed wrong all along..........but the thin plate that mounts on the back of your flywheel.

Has an inserted splined carrier with a half dozen springs around it.

Your Tranny shaft then slides into that plate and carrier.

Is that plate called a flex plate ??? If not what is it called cause I can't find them anywhere.

When I do search for flex plates these sheetmetal looking flywheels come up.

Thanks
Jon

A flex plate and a fly wheel do essentially the same thing. In an automotive application, a flywheel is for a manual transmission and the clutch bolts to it. A flex plate is for an automatic transmission and the torque converter bolts to it. Never having taken the back end of a marine engine apart, I don't know if they use a fly wheel or a flex plate.

What you are looking for is called a Drive plate. When I redid my engines and transmissions I replaced mine. I got them from Innovation engineering in Georgia. Their number is (770) 972-2972 I was very pleased with them. They make them for a lot of companies.

Good luck

Depends on which outdrive you are running. If it's a Bravo, you have a "coupler" bolted to the crankshaft of the engine. The coupler is a flywheel type apparatus that has a splined female connection in the center that's impregnated in rubber. When the drive is installed, the splined input shaft from the Bravo slides through the gimbal housing into the female splines on the coupler.

If the boat has TRS or Speedmasters, it has a transmission that bolts between the engine and the outdrive. I would assume they use a type of flex-plate/flywheel to connect the transmission to the engine. I've never owned a boat with trannys so I can't give you a solid answer.

What would it cost to take the TRS plug in taile off of my Huber 1050 and replace it with a #6 plug in tail stock. I am understanding the basic tranny case is the same.
