sporadic speedometer

[ssaamm]

Hi, I have a 90hp 4stroke '02 Yamaha on a 17ft Crestliner Fish Hawk. The speedometer on the dash will work for a couple of months and then just show a "-". Not a big deal for me, but is there a sensor on the motor that could be clogged or is there a fairly simple solution or test I could run. Not a big issue, the Gps shows the speed just fine. Thanks for the help. Sam

The little water intake on the motor may be plugged with a little piece of wood. Did you hit any sticks in the past couple of trip?

Usually in the spring a few of my boats hit sticks floating or logs and the speedometer intake gets pluged.

Simple fix, we just use a straightened out jig to pull the wood fibers out of the hole.

Thanks for the reply. I did clean out the little hole on the lower unit. When I did this I noticed that my anode ( or fin right above the prop) was twisted off center a couple of inches. The boat does pull a little bit. Is this a big deal? I tried pushing it back with no luck. Thanks, Sam

You didn't mention which way it's pulling. But in most instances it will be a little to the right to counter for the prop. If it pulls to the left, move it slightly to the left. If it pulls right, move slightly to the right.

How do you move it? Can it break anything? Thanks for the reply. Sam

Look directly above it - there's probably a round plastic cap on there - pop it out, loosen the bolt and rotate as you wish.
