I took my boat to the lake yesterday for the first time this year and it
cranked right up, when I gave it full throttle, I got high RPM's but no
speed, we were only doing about 5 mph. It worked fine last year before I
put it up.

It is a 2002 Mercury 90 HP.

Any help would be appreciated.

Check your propeller hub to see if it has spun.

Spun prop hub.

So, your engine is turning at around 5K and you are only doing 5MPH.

If you had a clutch, which I you don't, it could be slipping

That pretty much leaves the Prop more or less free wheeling or something
really strange going on in the lower unit.

As the others said, it could be a spun prop. This means the rubber
layer between the inner hub and the prop has let loose. It's designed
to let loose if you hit an object with the prop to protect the inner
workings of the engine - like a shock absorber. Sometimes they just
wear out,I guess, although I've never personally experienced that, it
seems to happen. It can be fixed by a prop shop. If you don't have a
spare prop, this might be a time to buy one - to use while the old prop
is in the shop and to have as a spare for the future. If your current
prop is stainless, buy an aluminum one for the spare.

Sell it, and get a 175.

And no, its not true, that people with long driveways are
"compinsating" for a small penis.
