Cruisin along about 3200 and Boat comes off plane and port motor seems to spin free .... Coupler or maybe the Hub ?

If it is your coupler you will see shards of burnt rubber all over your rear engine compartment. Sounds like your drive to me.

If it is the hub you may experience intermitent slipping.

Feel free to call.

Well at least you got the overheating problem fixed , right?
Could also have taken out the splines in the coupler

what did I read about turning the props by hand ? If I can tell a noticable difference ? With drives up and in gear it will turn at Idle ....but if you lower the drive and put load on it doesnt spin ...

Yup runs cool as a cucumber now ....just dont spin ! ..we'll get it though ..If its the coupler ..thats gona hurt ....JUST had that motor out ...

Run the engine with drive down and in gear and take a look at the drive shaft.
If it rotates, it's not the coupler. If it not rotates ...

Bingo ...merc Flo Torque Drive Hub ....41.00 ..Damn I'm Glad That Motor doesnt have to come out .......

Smell the lube in your outdrive ,if it smells burnt your drives gone.

OK .. found out I have the press in type hub ....So question now is ...do I invest in another set of props as spares ...or get newer props with quick change hubs ...or ..I read where cpl of 311's are running Hydromotive's QIV ...(Russ) ...
