Ok, was running down Torch Lake this afternoon 3000RPM on plane and all of a sudden it felt like it went into neutral...?? you would have thought that the prop came off. Can not find any issues looking at the engine or drive. had to get towed back to the launch. Engine revs but ro reverse or forward ..
Boat is a 1986 23 powerplay SBC with a Alpha Drive.
Any Ideas??

Is outdrive shot..??

Shift cable??

Thanks,

Steve

Does your prop uses the Flo torq HUB? Have you had a look at it? It may be the problem

check your coupler.. I had two go on me when i was running bravo drives.
Good Luck!! Hope all works out for you.

what do I look for in a flow HUB?? But on the trailer you can spin the prop and feel it make a click click when you spin it by hand??

what do I look for in the coupler....a gap??

Do a search here on OSO, a lot of good ideas on how to determin if it`s the coupler.

When you pull the drive it'll either bind on you or you will see metal shavings. After the drive is pulled you can easily inspect the coupler.

I forgot to mention that it is a Sternmaster outdrive ...??? a Merc Knock off but it only has like maybee 80 hours on it ??

The Hub is simply a removable black plastic insert inside your prop (Early 90's Props and up). If you have this system, simply remove and inspect.

The waterpump is working?? the motor never got hot?? If that helps at all.
